Product Description

Spherical surface ball Bearings
Insert spherical bearings are preferred for occasions requiring simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery. It is mainly used to bear combined radial and axial loads, mainly radial loads. Generally, it is not suitable to bear axial loads alone. This kind of bearings can be installed with inner rings (with a full set of rollers and cages) and outer rings respectively. This kind of bearing does not allow the shaft to tilt relative to the housing, and will generate additional axial force under the radial load. The size of the axial clearance of this kind of bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easy to be damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be used to increase the rigidity of the bearing.

Pillow block bearings play a crucial role in ensuring the efficient operation of conveyor systems. Their contributions can be outlined as follows:

  • Support and Load Handling:
  • Pillow block bearings provide support for the rotating shafts in conveyor systems. They are responsible for handling and transmitting the loads applied to the conveyor, including the weight of the conveyed material and any external forces. By effectively supporting the shaft, pillow block bearings help maintain the structural integrity of the conveyor and ensure smooth and efficient movement of the material.

  • Reduced Friction and Wear:
  • Pillow block bearings are designed to minimize friction between the rotating shaft and the bearing housing. They incorporate rolling elements, such as balls or rollers, which facilitate smooth motion with reduced friction. By reducing friction and wear, pillow block bearings help optimize the energy efficiency of the conveyor system, minimizing power consumption and extending the lifespan of the bearings and other related components.

  • Alignment and Stability:
  • Proper alignment of the conveyor components is essential for efficient operation. Pillow block bearings aid in aligning and supporting the shaft, ensuring that it remains centered and in the correct position. This alignment helps prevent excessive vibrations, reduces the risk of misalignment-related issues, and promotes stable and consistent performance of the conveyor system.

  • Protection and Contamination Prevention:
  • Pillow block bearings are designed to provide protection against contaminants, moisture, and debris in the operating environment. They often incorporate sealing mechanisms, such as rubber seals or labyrinth seals, to prevent the entry of foreign particles into the bearing. This protection helps maintain the cleanliness of the bearing’s internal components, reducing the risk of premature wear, corrosion, or damage. By preventing contamination, pillow block bearings contribute to the efficient and reliable operation of the conveyor system.

  • Maintenance and Accessibility:
  • Conveyor systems require periodic maintenance, including bearing inspection, lubrication, and potential replacement. Pillow block bearings are designed with ease of maintenance in mind. They often feature a split housing design that allows for convenient access to the bearing without disassembling the entire conveyor system. This accessibility simplifies maintenance tasks, reduces downtime, and promotes efficient upkeep of the bearings, ensuring the long-term reliability and performance of the conveyor system.

In summary, pillow block bearings contribute to the efficient operation of conveyor systems by providing support, handling loads, reducing friction and wear, ensuring alignment and stability, protecting against contaminants, and offering ease of maintenance. With their essential role in supporting and facilitating the movement of conveyor shafts, pillow block bearings help optimize the performance, energy efficiency, and longevity of conveyor systems.

Can you explain the design principles of pillow block bearings and their functions?

Pillow block bearings, also known as plummer block bearings, are designed based on certain principles to ensure their functionality and performance. Understanding the design principles can provide insights into how these bearings operate and fulfill their intended functions. Here’s a detailed explanation of the design principles of pillow block bearings and their functions:

  • Housing Design:
  • The housing of a pillow block bearing is typically made of cast iron or pressed steel and has a split design. The split housing allows for easy installation and maintenance by providing access to the bearing insert without the need to disassemble the entire system. The housing also includes mounting holes or slots for attaching the bearing to a support structure, such as a machine frame or conveyor system.

  • Bearing Insert:
  • The bearing insert is a key component of a pillow block bearing. It is pre-mounted inside the housing and provides the rotating element to support shafts or other moving parts. The design of the bearing insert depends on the specific application requirements. Common types of bearing inserts used in pillow block bearings include deep groove ball bearings, spherical roller bearings, and cylindrical roller bearings. The selection of the appropriate bearing insert depends on factors such as load capacity, speed, and environmental conditions.

  • Self-Aligning Capability:
  • Pillow block bearings are designed with a certain degree of self-aligning capability. This means that they can accommodate slight misalignments or shaft deflections without causing undue stress on the bearing or affecting its performance. The self-aligning capability is achieved through the design of the bearing insert and the housing. It helps to ensure smooth operation, reduce wear, and prolong the bearing’s service life.

  • Load Support:
  • Pillow block bearings are primarily designed to support rotating shafts and transmit loads between the shaft and the housing. They are capable of handling both radial and axial loads, depending on the type of bearing insert used. The design of the bearing insert and the housing is optimized to provide optimal load-carrying capacity and distribute the loads evenly, minimizing stress concentrations and maximizing the bearing’s performance.

  • Lubrication:
  • Lubrication is crucial for the proper functioning and longevity of pillow block bearings. The housing design often includes provisions for grease or oil lubrication. Lubrication helps to reduce friction, dissipate heat, prevent wear, and protect against corrosion. Proper lubrication ensures smooth operation, minimizes power losses, and extends the service life of the bearing.

  • Environmental Protection:
  • Pillow block bearings are designed to provide a degree of environmental protection to the bearing insert. The housing acts as a shield, preventing contaminants such as dust, dirt, and moisture from entering the bearing and causing premature failure. The housing design may include features such as seals or shields to further enhance the protection against contaminants. This design principle helps to maintain the integrity of the lubrication and ensure reliable operation in various working environments.

In summary, pillow block bearings are designed based on certain principles to ensure their functionality and performance. The housing design allows for easy installation and maintenance, while the bearing insert provides the rotating element to support shafts and transmit loads. The self-aligning capability accommodates misalignments, and the optimized design of the bearing insert and housing ensures proper load support. Lubrication and environmental protection features contribute to smooth operation and extended service life. Understanding these design principles helps in selecting and utilizing pillow block bearings effectively in various industrial applications.

Slewing ring bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction .They can perform both slewing (oscillating) movements as well as rotational movements. A slewing ring bearing consist of an inner ring, an outer ring and rolling elements (balls or cylindrical rollers) that are separated by polyamide spacers .The rings, 1 of which usually incorporates a gear ,are provided with holes to accommodate attachment bolts. The holes may be threaded. Generally , only the raceways in the rings are hardened and precision-ground.Integral seals made of acrylonitrile-butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing. Slewing ring bearings are re-lubricated through grease fittings to reduce maintenance and operating costs.

Compared to traditional pivot arrangements, slewing ring bearing arrangements provide many design and performance advantages. The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components .The low sectional height of these bearings means that the pinion lever can be kept short. In most cases only flat mounting surfaces on the associated components are needed.

Slewing ring bearings were originally designed to be mounted only on horizontal support structure, but can now be used successfully in vertical bearing arrangements .

Slewing ring bearings perform extremely well in a variety of applications such as:
¤ Access platforms
¤ Bucket wheel excavators
¤ Conveyor booms
¤ Cranes of all type
¤ Small ,medium and large excavators
¤ InHangZhou tables
¤ Ladle turrets
¤ Offshore applications
¤ Robots
¤ Railway bogies
¤ Rotary platforms
¤ Stackers
¤ Solar mirrors
¤ Tunnel boring machines
¤ Wind turbines

The housing is typically a split design that allows for easy installation and maintenance. It usually has a flat base with mounting holes for attachment to a support structure, such as a machine frame or conveyor system. The bearing insert is pre-mounted inside the housing and provides the rotating element to support shafts or other moving parts.

  • Supporting Shaft Loads:
  • Pillow block bearings are primarily used to support rotating shafts and transmit loads between the shaft and the housing. They are capable of handling both radial and axial loads, depending on the type of bearing insert used. The design of the pillow block bearing allows for self-aligning capability, which helps accommodate slight misalignments or shaft deflections, ensuring smooth operation and reducing stress on the bearing.

  • Easy Installation and Maintenance:
  • One of the key advantages of pillow block bearings is their ease of installation and maintenance. The split housing design allows for quick assembly and disassembly without the need to remove other components or disassemble the entire system. This feature simplifies bearing replacement, lubrication, and inspection, reducing downtime and maintenance costs in industrial applications.

  • Versatility and Adaptability:
  • Pillow block bearings are highly versatile and adaptable to various industrial applications. They can be found in a wide range of industries, including manufacturing, mining, agriculture, construction, and material handling. These bearings are used in conveyor systems, power transmission equipment, pumps, fans, compressors, and many other rotating machinery applications.

  • Environmental Protection:
  • Pillow block bearings are designed to provide a degree of environmental protection to the bearing insert. The housing acts as a shield, preventing contaminants such as dust, dirt, and moisture from entering the bearing and causing premature failure. Additionally, the housing design often includes provisions for grease or oil lubrication, further protecting the bearing and ensuring proper lubrication for optimal performance.

  • Specialized Variations:
  • While the basic design of pillow block bearings remains the same, there are specialized variations available to meet specific application requirements. These include corrosion-resistant bearings for harsh environments, high-temperature bearings for elevated temperature applications, and sealed bearings for applications where additional protection against contamination is needed.

In summary, pillow block bearings are bearing units housed in a block or housing, widely used in various industrial applications. They provide support for rotating shafts, transmit loads, accommodate misalignments, and offer easy installation and maintenance. Their versatility, adaptability, and environmental protection make them suitable for diverse industrial sectors. With specialized variations available, pillow block bearings can be customized to meet specific application needs, ensuring reliable and efficient operation in a wide range of industrial machinery and equipment.

How does proper lubrication impact the performance and longevity of pillow block bearings?

Proper lubrication plays a crucial role in the performance and longevity of pillow block bearings. It ensures smooth operation, reduces friction and wear, dissipates heat, and protects against corrosion. Here’s a detailed explanation of how proper lubrication impacts the performance and longevity of pillow block bearings:

  • Reduced Friction and Wear:
  • Lubrication forms a thin film between the rolling elements and the raceways of the pillow block bearing. This film of lubricant reduces friction and minimizes wear by providing a lubricating barrier between the moving surfaces. Reduced friction results in lower energy consumption, less heat generation, and decreased wear on the bearing components, leading to improved performance and prolonged service life.

  • Heat Dissipation:
  • During operation, pillow block bearings can generate heat due to the friction between the rolling elements and the raceways. Proper lubrication helps to dissipate this heat by carrying it away from the bearing surfaces. Effective heat dissipation prevents excessive temperature rise, which can cause lubricant degradation, thermal expansion, and accelerated wear. By maintaining proper lubrication, the pillow block bearing can operate within the desired temperature range, ensuring optimal performance and preventing premature failure.

  • Protection Against Corrosion:
  • Lubrication provides a protective barrier that helps to prevent corrosion and rust formation on the bearing surfaces. Corrosion can occur when moisture or contaminants penetrate the bearing and react with the metal surfaces. The lubricant acts as a barrier, preventing direct contact between the metal surfaces and the external environment, thus inhibiting corrosion and preserving the integrity of the bearing components. Proper lubrication with corrosion-resistant lubricants is particularly important in environments with high humidity, exposure to water, or corrosive substances.

  • Prevention of Contamination:
  • Pillow block bearings are susceptible to contamination from dust, dirt, and other particles present in the operating environment. Proper lubrication with appropriate sealing or shielding options helps to prevent the ingress of contaminants into the bearing. The lubricant forms a protective barrier, sealing off the bearing and reducing the risk of particle intrusion. By minimizing contamination, proper lubrication helps to maintain the smooth operation and integrity of the bearing, preventing premature wear and failure.

  • Extended Service Life:
  • By ensuring proper lubrication, the performance and longevity of pillow block bearings can be significantly improved. Proper lubrication reduces friction, wear, and heat, while providing protection against corrosion and contamination. These factors collectively contribute to the extended service life of the bearing. Regular lubrication maintenance, including monitoring the lubricant condition, replenishing or replacing the lubricant as necessary, and following the manufacturer’s recommendations, helps to maximize the service life of the pillow block bearing and optimize its performance.

In summary, proper lubrication is essential for the performance and longevity of pillow block bearings. It reduces friction and wear, dissipates heat, protects against corrosion, and prevents contamination. By maintaining proper lubrication, the pillow block bearing operates smoothly, experiences less wear, and remains protected from external factors, leading to improved performance, extended service life, and enhanced reliability.

Understanding the Different Types of Bearings

When you are looking for a bearing, you have many options to choose from. This article will explain the various types, functions, and working principles of different types of bearings. Once you understand the basic components, you can make an informed decision about which one to buy. Here’s an overview of some of the most common types. Learn more about each type below! Read on to learn about the differences between these different types of bearings! Posted in Articles

Functions

Bearings serve as an integral part of a mechanical device. These devices help transfer torque from one part of a structure to another. These mechanisms increase the efficiency of a shaft by increasing its life. However, the functions of bearings depend on the application of the structure. Among other functions, bearings provide support to shafts. Anti-friction bearings come in two types: ball and roller bearings. These components have line and point contact, which is the most common type. Archimedes’s principle states that the force is equal to the weight of the fluid that is being displaced. Bearings can transfer lateral loads to a substructure.
A bearing has two primary functions. The first is to prevent direct metal-to-metal contact. A bearing prevents friction, heat generation, and wear and tear of components. A bearing also reduces energy consumption. Its other purpose is to guide and support a rotating body. In addition to these functions, bearings can also reduce wear and tear on a machine. As a result, they are among the most widely used machines in the world.
Seals are a major component of a bearing. They prevent foreign materials from entering and lubricating the moving parts. The design of seal lips determines their effectiveness. Fuel economy regulations and CO2 emissions regulations are pushing the demand for low-friction bearings. However, high-performance seals do not always provide high-performance. As a result, current estimations of the friction in bearings depend on trial and error methods.
Another important function of bearings is that they transfer the load of a rotating component to its housing. This load can be axial or radial. Bearings also limit movement to predefined directions. Some types of rolling element bearings have balls or cylinders inside. These bearings are less frictional than sliding ones, thus they allow parts to move freely during rotation. These parts can then be used for various applications. So, bearings are an integral part of machines.

Types

The most common type of bearing is a plain bearing. It uses surfaces in rubbing contact to transmit movement from one part to another. These bearings may be discrete or may consist of a hole in a metal sleeve or a planar surface bearing another part. Some plain bearings are flanged, while others are made of a sleeve with a flange at one end. These bearings often give acceptable accuracy and life, but they are expensive and cannot be used in large scale applications.
Radial bearings are used when there is a need for high-speed or corrosive parts. This type of bearing also serves as a support in an intermediate situation. Its two components are called the base and the cover. The base and cover are connected and are arranged parallel to the main axis. This type of bearing is used in steady-state and axial motion applications. The radial bearings are also used when the shafts are long.
Angular contact bearings are another type of bearing. These are easy to install and require minimal maintenance. Their races are displaced along the axis. They are also better at handling axial loads and transferring them to the housing. These types of bearings are commonly used in pumps, automobiles, and high-speed applications. If you are looking for an affordable, reliable bearing, look no further than the angular contact bearing.
Another type of bearing is a self-lubricating bushing. These are lightweight and wear-resistant. Unlike the other types of bearing, they do not require any lubrication or maintenance. In fact, some are completely maintenance-free. But if you’re worried about maintenance, this type of bearing may be a good choice. There are many benefits of using self-lubricating bushings. It is also a good option for applications where your machine is exposed to extreme temperatures.

Working principle

bearing
A bearing has two primary functions: support and load transfer. In engineering applications, the bearing tends to push the load in the direction of the shaft. A radial load pushes the bearing downward and a thrust load pushes it sideways. Both types of load transfer are important in a variety of applications. The working principle of each type is described below. Listed below are the main uses for each type of bearing.
A plain bearing uses a PTFE liner on the interface of two moving parts. The PTFE liner acts as a lubricant and may be filtered to alter its friction. The journal bearing uses the motion of the journal to force fluid into the gap between two moving parts. This results in a small amount of play in the bearing. This play is acceptable for most applications. A ball bearing may have a maximum play of 2 mm for a ten-millimeter shaft.
The primary function of a bearing is to assist in rotation and to reduce mechanical friction between the two objects. A bearing may be installed as a separate device or as an integral part of a machine. For more complex applications, bearings are very precise components requiring the highest standards of technology. For this reason, it is important to understand the working principle of bearings. The next time you need to lift or slide a heavy object, consider a bearing.
Ball bearings are a common type of ball bearing and can be found in industrial machinery and automobiles. Their unique structure helps them support less weight. This is because they are comprised of two rings – an inner race and an outer race. The balls themselves have a small area of contact and transfer axial loads in one direction. A cage surrounds the balls and prevents them from colliding. This makes ball bearings a popular choice for many applications.

Sealing system

A bearing’s seals are vital for the operation of rolling and rotating components. These systems enable rotation and linear movement while limiting friction and dispersing stress. Without the proper seals, these components could face catastrophic failure. In addition to protecting the bearing from external forces, seals help retain lubricant inside the system and prevent harmful particles from entering the gap. A seal’s lubrication helps prevent the onset of mechanical damage and prolongs the life of the bearing.
A bearing seal is made up of two parts: the inner sealing element and the outer sealing element. A passageway runs through the bearing assembly to the outer seal element. A hydraulic press or pneumatic jack is recommended for installing the seal. These tools are effective in reducing deformation and improving seal installation quality. When fitting the seal, ensure that the tool does not hit the seal directly. A proper adopter will distribute the load uniformly across the seal.
The seal’s efficiency depends on its gap. A four-inch shaft seal can flow 0.5 standard cubic feet per minute. A seal’s efficiency is highly dependent on the gap size. The gap size is a cube of the flow through the system. A smaller gap size allows high flow and pressure but less leakage. If both surfaces of the seal have similar pressures and flow rates, the seal is efficient. However, a small gap reduces the pressures and reduces wear.
Mechanical seals have numerous advantages, including their ability to protect against contaminants and splashing liquids. Labyrinth seals are the first line of defense against leaks. They operate without friction. Their high level of sealing efficiency helps ensure that the bearing remains operational for long. This type of seal is made from metal plates and is designed for a wide temperature range and misalignment. Its advantages include being easy to install and offering 100% sealing efficiency.

Maintenance

bearing
Bearing maintenance is critical to ensuring that your bearings keep operating at their peak performance. Proper maintenance will improve bearing life, reduce downtime and increase productivity while reducing costs. Here is an 8-point checklist to optimize your bearings and make them last longer. To optimize their performance, you should follow these steps regularly. In case a bearing does not last long, you should replace it as soon as possible. Listed below are some tips to ensure proper maintenance.
The first step is to determine how often your bearings require lubrication. Some manufacturers recommend that you lubricate them weekly, but this can do more harm than good. Instead, use ultrasound to measure the level of friction and trend its levels. This way, you will know exactly when to grease your bearings. It’s also important to check how often they should be inspected and calibrated. A professional can provide guidance on proper maintenance.
Next, inspect your bearings for cracks and scratches. You should never install a bearing that has been dropped or scratched. Even a small crack will affect the performance of the bearing and could lead to its premature failure. A proper alignment is essential for the bearing to function properly. Make sure you have the correct tools to perform this task. These tools can help you reduce manual work and promote safe bearing maintenance. You should also ensure that the shaft and housing are clean and undamaged.
Proper maintenance can prolong bearing service life. Proper lubrication, mounting, inspection, basic condition monitoring, and dismounting can extend their life. Proper maintenance extends their lifespan and improves plant productivity. While bearings are essential for machinery, you should make sure you follow the proper safety procedures every time you work with them. These tips will also help prevent accidents and maintain your machine’s efficiency. Once you’ve followed these guidelines, you can safely inspect your bearings and ensure that they’re operating at their optimum capacity.

ZYS Tapered roller bearings

Main structural forms

1.Single row tapered roller bearing

Single row tapered roller bearing can limit the axial displacement of the shaft or shell in 1 direction and bear the axial load in 1 direction. Additional axial force is generated under the action of radial load. Therefore, in the 2 supports of the shaft, the end faces of bearing outer ring and bearing inner ring are oppositely mounted. If used alone, the applied axial force must be greater than the additional axial force. The 313 series tapered roller bearings have large contact angles (27°~ 30°) and can withstand large axial loads. The contact angle of tapered roller bearings in other series is between 10°and 18°.

2. Double row tapered roller bearing

Double row tapered roller bearing has a pair of raceway outer ring and 2 inner rings, and a middle spacer between the 2 inner rings. The thickness of the spacer can be adjusted to adjust the bearing clearance. Double row tapered roller bearing can bear the bidirectional axial load while bearing the radial load. It can limit the bidirectional axial displacement of the shaft or shell within the axial clearance range of the bearing.

3. Four row tapered roller bearings

Four row tapered roller bearings adopt 2 double raceway inner rings, 1 double raceway outer ring and 2 single raceway outer rings, and there are spacers between inner ring and outer ring for adjusting clearance. It has similar performance with double row bearing: large radial load and low limit speed. Four row tapered roller bearings are mainly used for heavy machinery, such as rolling mill.

How does proper lubrication impact the performance and longevity of pillow block bearings?

Proper lubrication plays a crucial role in the performance and longevity of pillow block bearings. It ensures smooth operation, reduces friction and wear, dissipates heat, and protects against corrosion. Here’s a detailed explanation of how proper lubrication impacts the performance and longevity of pillow block bearings:

  • Reduced Friction and Wear:
  • Lubrication forms a thin film between the rolling elements and the raceways of the pillow block bearing. This film of lubricant reduces friction and minimizes wear by providing a lubricating barrier between the moving surfaces. Reduced friction results in lower energy consumption, less heat generation, and decreased wear on the bearing components, leading to improved performance and prolonged service life.

  • Heat Dissipation:
  • During operation, pillow block bearings can generate heat due to the friction between the rolling elements and the raceways. Proper lubrication helps to dissipate this heat by carrying it away from the bearing surfaces. Effective heat dissipation prevents excessive temperature rise, which can cause lubricant degradation, thermal expansion, and accelerated wear. By maintaining proper lubrication, the pillow block bearing can operate within the desired temperature range, ensuring optimal performance and preventing premature failure.

  • Protection Against Corrosion:
  • Lubrication provides a protective barrier that helps to prevent corrosion and rust formation on the bearing surfaces. Corrosion can occur when moisture or contaminants penetrate the bearing and react with the metal surfaces. The lubricant acts as a barrier, preventing direct contact between the metal surfaces and the external environment, thus inhibiting corrosion and preserving the integrity of the bearing components. Proper lubrication with corrosion-resistant lubricants is particularly important in environments with high humidity, exposure to water, or corrosive substances.

  • Prevention of Contamination:
  • Pillow block bearings are susceptible to contamination from dust, dirt, and other particles present in the operating environment. Proper lubrication with appropriate sealing or shielding options helps to prevent the ingress of contaminants into the bearing. The lubricant forms a protective barrier, sealing off the bearing and reducing the risk of particle intrusion. By minimizing contamination, proper lubrication helps to maintain the smooth operation and integrity of the bearing, preventing premature wear and failure.

  • Extended Service Life:
  • By ensuring proper lubrication, the performance and longevity of pillow block bearings can be significantly improved. Proper lubrication reduces friction, wear, and heat, while providing protection against corrosion and contamination. These factors collectively contribute to the extended service life of the bearing. Regular lubrication maintenance, including monitoring the lubricant condition, replenishing or replacing the lubricant as necessary, and following the manufacturer’s recommendations, helps to maximize the service life of the pillow block bearing and optimize its performance.

In summary, proper lubrication is essential for the performance and longevity of pillow block bearings. It reduces friction and wear, dissipates heat, protects against corrosion, and prevents contamination. By maintaining proper lubrication, the pillow block bearing operates smoothly, experiences less wear, and remains protected from external factors, leading to improved performance, extended service life, and enhanced reliability.
