Spherical roller bearings are designed with two row rollers running between an inner ring of two raceways and an outer ring with a spherical raceway. This allows these bearings to support both an axial and radial load, and the high radial load capacity ensures the spherical roller bearings are ideal for heavy load or impact load conditions.
Shown in the figures, types C, CK…K, CA and CA…K, which are designed for high load capacity, are available. Types C and CK…K have pressed steel cages, and Types CA and CA…K has machined brass cages.”

An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.
When bearings with a hole for a locking pin to prevent outer ring rotation are required, please inform Peple parts.
Permissible Misalignment
The permissible misalignment of spherical roller bearings varies depending on the size and load, but it is approximately 0.018 to 0.045 radian (1°to 2.5°) with normal loads.
Limiting Speeds
The limiting speeds listed in the bearing tables should be adjusted depending on the bearing load conditions. Also, higher speeds are attainable by making changes in the lubrication method, cage design, etc.
Main application
Spherical roller bearings feature a wide array of applications, including paper machinery, speed reducers, printing machinery, woodworking machinery, crushers and more. We offer two bearing types, comprised of cylindrical and tapered holes. Among which, users can not only install the tapered hole bearings directly, also can mount it on the cylindrical axis using an adapter sleeve and a bushing. We offer customized spherical roller bearing size.
Cylindrical roller bearings are equipped with a cage between the rollers, which prevents the roller from tilting or rubbing against other rollers, and efficiently balancing the increase in the rotation torque. This series includes single row cylindrical roller bearings, and double row cylindrical roller bearings.
Single row cylindrical roller bearings are separable, and are capable of bearing only a radial load. This makes them ideal for large electrical machinery, such as a tractor gear box.
Double row cylindrical roller bearings are compact, rigid, and feature a large load bearing capacity, making them ideal for spindle bearings in machine tool spindles.
PRECAUTIONS FOR USE OF CYLINDRICAL ROLLER BEARINGS
If the load on cylindrical roller bearings becomes too small during operation, slippage between the rollers and raceways occurs, which may result in smearing. Especially with large bearings since the weight of the roller and cage is high.
In case of strong shock loads or vibration, pressed-steel cages are sometimes inadequate.
If very small bearing load or strong shock loads or vibration are expected, please consult with Peple Parts for selection of the bearings.
Bearings with molded polyamide cages can be used continuously at temperatures between —40 and 120°C. If the bearings are used in gear oil, nonflammable hydraulic oil, or ester oil at a high temperature over 100°C, please contact Peple Parts beforehand.
PERMISSIBLE MISALIGNMENT
The permissible misalignment of cylindrical roller bearings varies depending on the type and internal specifications. For double-row cylindrical roller bearings, nearly no misalignment is allowed.
Single-row cylindrical roller bearings are designed with a separable structure that is comprised of both inner and outer rings, and feature a high load capacity that is suitable for large electrical machinery, machine tool spindles and gearboxes and more.
Based on the different structures, we offer a variety of types, including the N-type, NU-type, NUP-type and NF-type. Users can choose the right bearing for their needs. Types NU and N are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction.
Types NUP can be used as fixed-end bearings. Our recommendations are below, based on the different single row cylindrical roller bearing structures.
Double row cylindrical roller bearings are movable bearings that are designed with a removable structure that make them easy to install and remove. The two row rollers are arranged side by side, making the bearings capable of supporting a high radial load in high rotational speed working conditions.
Tapered roller bearing load capacities depend on the raceway angle of the positive outer ring. The greater the angle, the greater the carrying capacity. This is different from different angular contact ball bearings made from a variety of materials. Our recommendations are listed below.
Single Row Tapered Roller Bearings
The cone angle of the outer ring raceway ranges from 10° to 19°, and can support a combination load from both axial and radial directions, making them ideal for lathe spindles and compressors.
Double row tapered roller bearings are capable of bearing both an axial and radial load. They also feature a high rigidity, making them ideal for gear boxes, lifting equipment, rolling mills, and mining machinery.
Four row tapered roller bearings can accommodate a higher radial load, while the limiting speed is slightly lower. These bearings are ideal for use in heavy duty machinery.
Single-row tapered roller bearings are comprised of the outer ring, inner ring, tapered roller and retainers. The outer ring is detachable from the inner ring assembly, and users can exchange the outer or inner ring assemblies of any standard tapered roller type with the same model according to ISO standards for tapered roller bearing dimensions.
Main application: The cone angle between the outer ring and raceway of single tapered roller bearings generally ranges from 10°to 19°, ensuring it is capable of supporting a combination load from both axial and radial directions. This bearing series is often used in vehicle front wheels, transfer rollers, lathe spindles and pinion devices. In addition, the rib surface is smooth and clear, thus assisting in the formation of a lubrication film to reduce fabrication and lower wear costs, as well as extend the service life.
The inner ring and outer ring of the double row tapered roller bearings are an integrated whole. Both the small end face of the inner and outer rings are close to each other, and the space ring in the middle will adjust the clearance. The double row tapered roller bearing can support both a radial and axial load, as well as features a high rigidity, making it applicable for gear boxes, lifting equipment, rolling mills, mining machinery, and more.
Features
Double-row tapered roller bearings are comprised of two row rollers, and features a high load capacity.
The high dimensional accuracy reduces noise and vibration levels.
The roller surface and raceway contact surface is clear and smooth, making it available for the formation of lubricant film, which helps reduce friction, thus extending the service life.
Four-row tapered roller bearings are designed with two double-raceway inner rings, one double-raceway outer ring and two single-raceway outer rings, allowing them to support an extremely high radial load, axial load and impact load, and making them suitable for high speed working conditions. We can produce the four row tapered roller bearings in a variety of dimensions to meet different customer requirements.
Features
Our bearings are made of bearing steels that have a hardness of up to HRC61-65, thus ensuring a better wear resistance.
Between the inner ring and outer ring of the bearings, there is a space ring to adjust the clearance between the bearings, and prevent them from becoming damaged during operation. The temperature will increase if the axial clearance is too small or too large, which causes the bearings to become worn faster, and reduces the service life, which is why a space ring is added for the prevention of the temperature rise.
These roller bearings feature an outstanding leak resistance, which prevents outer contamination, and maintains friction and heat generation at minimum levels, thus reducing maintenance costs.
Deep groove ball bearings are a multi-function bearing, and are comprised of a firm inner ring, outer ring, and ball retainer. They are capable of simultaneously supporting both a radial and axial load, with the contact angle at 0 when they are supporting only a pure radial load. This ensures a high rotation speed, making the ball bearing applicable for high speed working conditions.
Application
Deep groove bearings feature a low maintenance cost and small fabrication, which makes them ideal for a wide range of applications, including precision instruments, household electrical appliances, transmission, agricultural machinery, construction machinery, engineering machinery and more.
Features
- Deep groove bearings are metric bearings produced in accordance with ISO standards. The bearing elements are interchangeable with other brands, such as the inner and outer rings.
- Deep groove bearings are equipped with superior grease lubricants, which help reduce friction and lower noise levels during operation.
- We also offer a variety of brass retainers, which feature an excellent durability that makes them suitable for use in harsh work conditions.
Angular contact ball bearings can support both radial and axial loads. The axial load capacity is determined by the contact angle: the larger the contact angle, the higher the axial load capacity. Angular contact bearings are generally divided into several types according to the contact angle including 7000C-type (α＝15°), 7000AC-type (α＝25°) and 7000B-type (α＝40°).
Single row angular contact ball bearings are capable of supporting only a unidirectional axial load, which makes them ideal for use in machine tool spindles, high-frequency motors, gas turbines, centrifuges, minicar front wheels, difference velocity machine pinion shafts, booster pumps, drilling platforms and food machinery.
Double row angular contact ball bearings are capable of supporting both a radial and axial load, making them ideal for working conditions with high rigidity requirements, such as oil pumps, root blowers, and air compressors.
Four point contact ball bearings are designed specifically for oil free lubrication screw compressors. The 35°contact angular design will extend the bearing service life, thus minimizing maintenance costs.
The roller, inner ring and outer ring of single-row angular contact ball bearings is contacted via point contact, which can support radial load and unidirectional axial load. While this type of bearings will produce component force when it only supports radial load, then the installation in paired is required. Of particular note is that you need to make the pair of bearings face each other in the process of installation, which can avoid the additional axial load and limit the shaft or housing within the axial clearance. In addition, for single-row angular contact ball bearings, with the increase of contact angular, the axial load capacity will become higher, which is generally suitable for high-speed machines.
Main applications
Single-row angular contact ball bearings have a broad range of applications in various industries including main shaft of machine tool, high-frequency motor, combustion turbine, centrifugal machine, front wheel of minicar, differential pinion shaft, booster pump, drilling platform, food machinery, welding machine, low-noise cooling tower, electromechanical equipment, painting equipment, slot board of machine tool, arc welding machine, etc.
Features
Single-row angular contact ball bearings is made of bearing steel, featuring good rust-proof ability, which can prevent the bearings elements and product from rusting during the process of manufacturing, storing and using.
Single-row angular contact ball bearings offers two types of lubricant solutions including grease lubricant and oil lubricant. The appropriate amount ensures the stable rotation speed of bearings, avoiding more resistance caused by excessive use of lubricants and keeping a longer service life.
Double-row angular contact ball bearings keep consistent design with single-row angular contact ball bearings, however it takes up less axial space, featuring better rigidity, which is able of accommodate overturning moment. The contact angular is 30°，offering higher load capacity, which can support both radial and axial load. In addition, double-row angular contact ball bearings provide a good sealing, avoiding external environment contamination and lowering wear of raceway and roller, which helps reducing maintenance cost and extending service life. This type is used as fixed-end bearings. Their cages are pressed steel.
Main application
According to your requirements, we can produce various dimensions double-row angular contact ball bearings, mainly applied in equipment of oil pump, air blower, air compressor, various kinds of transmission, fuel injection pump, printing machinery and car front wheel hub, etc.
Four-point contact ball bearings is one type of separable bearings, the cross-section of inner and outer ring raceway is peach shape. The contact between steel balls and rings is four-point contact in both no-load or unidirectional radial load conditions. While there is two-point contact for unidirectional radial load, and can support biaxial load. While the four-point contact can support torque load. In addition, the double inner ring(outer ring) of four-point contact ball bearings is equipped with corresponding bearings, which can’t be replaced even for bearings with the same dimension. Four-point contact ball bearings are generally suitable for many industries including industrial pumps, compressors, petrochemical machineries, etc.
Features
The Four-point contact ball bearings are designed with separable structure. One single bearing can replace the angular contact ball bearing which is combined from the front or back.
Compared with other types of bearings, when the radial clearance of four-point contact ball bearings keep same, however, it offers lower axial clearance and high limiting rotation speed.
Instead of providing initial lubricants, four-point contact ball bearings offer grease lubricant or oil lubricant to lower wear and reducing maintenance cost.
Thrust ball bearings are made up of three parts: a cover ring, a shaft washer and a steel ball support. They can support axial loads, but not radial loads. This makes thrust ball bearings ideal for use in low-speed equipment that can only support a single axial load, such as crane hooks, speed reducers, vertical pumps, and hydraulic jacks. In addition, they have low noise, low temperature, and low friction, even in high-speed working conditions, making them suitable for harsh environments.
Features
- The cover ring, shaft washer, and roller are individual parts, making installation, removal, and maintenance simple.
- These bearings are made from high quality steel, which extends life up to 80% longer than other bearing materials.
- These thrust ball bearings are produced with grease location technology, reducing wear and maintenance costs.
