Q: HOW TO CHOOSE A BEARING?
To properly choose a ball bearing, the important thing is to take into account several parameters:
1. Its application
Bearings are everywhere and therefore their applications are varied:
- – Agriculture (agricultural machinery, tools, …)
- – Domestic (turntable, fishing rod, rollers, …)
- – Industry (assembly lines, industrial machinery, …)
- – Machines (tools, robots, …)
- – Vehicles (cars, motorcycles, bicycles, trailers, …)
- – Office (fans, ….)
- Â
- The application for which the bearing will be used will therefore be decisive in the choice of the part.
Â
2. The speed of rotation
The ball bearing supports high speeds and reduced loads, while the tapered roller bearing supports higher loads but lower speeds.
Â
The speed limits of a bearing are determined by the operating temperature.
The speed limit can be defined as the highest rotational speed a ride can achieve depending on use, without compromising performance and duration.
The speed limit of bearings depends on several factors, such as: bearing type, load size, tolerance class, cage configuration, work set, lubricant, lubrication and cooling conditions, etc.
Â
3. The supported load
2 types of loads are supported by bearings:
– Basic Dynamic Load
This is the maximum permissible load of the bearing capable of providing a nominal service life equal to 1 million revolutions.
It is necessary to calculate the service time necessary to show signs of fatigue on the materials, and on this basis to determine the theoretical duration.
– Static charge
This is the load that applies to the stationary bearing. It corresponds to a contact stress calculated between the rolling body in the most loaded contact and the raceway.
The loads are of simple type and radial, for the radial bearings, of simple type and axial, for
the abutments.
Â
4. Life of bearings
Bearing life is defined as the number of revolutions or hours of operation, which the bearing is CZPT to withstand before signs of fatigue appear on 1 of the rings, on the raceway or on the rolling elements.
Â
5. Nominal fatigue life
The rated fatigue life of an identical bearing or batch of bearings operating under the same service conditions shall be equivalent to at least a 90 degree of reliability.
The average life of a bearing lot is much greater than its nominal duration.
The nominal fatigue life is expressed as L10 (Million revolutions) or L10h (service hour).
Â
6. Bearing tolerance
Bearing tolerances have been standardized both nationally and internationally in accordance with ISO standards.
Bearings are generally manufactured in the P0 tolerance class.
Other parameters can be studied to choose the bearing best adapted to your needs:
- – The conditions of use and the constraints
- – The requirements of duration of the machine
- – The mimics of congestion of the bearing
- – Negative factors (vibration, shock, heat, dirt, acceptable sound level, etc.)
The choice of bearing is therefore mainly dictated by the dimension and load characteristics to which the bearing is subjected.
In order to supply even more stable quality to our vast customers, we established a factory in HangZhou city, ZHangZhoug province, China, near HangZhou and ZheJiang port, which has recognized by special ISO. The various bearings we produce there have been inspected and confirmed by SGS to be RoHS compliant.Â

How do cylindrical roller bearings differ from other types of roller bearings?
Cylindrical roller bearings possess distinct characteristics that set them apart from other types of roller bearings. Let’s examine the key differences between cylindrical roller bearings and other common roller bearing types:
- Design and Structure:
Cylindrical roller bearings feature cylindrical rollers that have a high length-to-diameter ratio. This design allows them to accommodate high radial loads and moderate thrust loads. In contrast, other types of roller bearings, such as spherical roller bearings or tapered roller bearings, have different roller shapes and configurations tailored for specific load and application requirements.
- Load Capacity:
Cylindrical roller bearings excel in handling radial loads. Their cylindrical roller arrangement and large contact area with the raceways enable them to distribute loads evenly along the rollers’ length. This characteristic makes cylindrical roller bearings suitable for applications where the primary load is radial. In comparison, other roller bearing types may be better suited for applications with different load orientations or combinations of radial and axial loads.
- Thrust Load Capability:
While cylindrical roller bearings can accommodate moderate axial loads, they are primarily designed for radial load-carrying capacity. On the other hand, thrust roller bearings, such as spherical roller thrust bearings or tapered roller thrust bearings, are specifically designed to handle predominantly axial loads. These thrust bearings have different roller arrangements and structures optimized for axial load resistance.
- Internal Clearance:
Cylindrical roller bearings offer a range of internal clearances, which is the space between the rolling elements and raceways when no external load is applied. The internal clearance affects factors such as running accuracy, thermal expansion, and the ability to accommodate misalignment or axial displacement. In contrast, other roller bearing types may have different clearance options or incorporate specific features, such as preloading, to optimize performance in their respective applications.
- Application Diversity:
Cylindrical roller bearings find extensive use in various machinery applications, including electric motors, gearboxes, pumps, and compressors. However, other roller bearing types have their own advantages and are commonly employed in specific industries or applications. For instance, needle roller bearings are suitable for applications with limited radial space, while crossed roller bearings are commonly used in precision machinery that requires high positioning accuracy.
- Operating Speed:
Cylindrical roller bearings can operate at high speeds, depending on their design and internal clearance. Manufacturers provide speed ratings and guidelines to ensure proper selection and operation within the bearing’s speed limits. Other roller bearing types may have different speed capabilities based on their specific design features, such as the shape of the rollers, cage design, or lubrication requirements.
Understanding the differences between cylindrical roller bearings and other types of roller bearings is crucial for selecting the appropriate bearing for a given application. Factors such as load requirements, load orientation, speed, space limitations, and environmental conditions should be carefully considered to ensure optimal bearing performance and longevity.
