Characteristics and Requirements of High Precision Bearings

May 09, 2023

Rolling bearings are commonly used accessories in the machinery industry and are indispensable. The price of the bearing is not only related to the material of the bearing, but also related to the precision grade of the bearing. The higher the precision grade, the more expensive the bearing. So for precision bearings, in addition to high precision, there are also requirements for other aspects. These high requirements jointly determine the precision of the bearing.

1. High speed. Under normal circumstances, high-precision bearings are mostly used in high-speed machinery and equipment. The speed is high, but the load is generally not too large. High rotation speed requires the bearing to take this factor into consideration in the design stage. If the load brought by the high speed may cause bearing deformation, etc. Only high speed can not solve the bad results brought by high speed, then this bearing is not a precision bearing.

2. High stiffness. High rotation speed must consider the stability of the bearing under torque load. Therefore, more attention should be paid to the selection of bearing materials and bearing structures.

3. High wear resistance. Precision bearings generally say that the load is not large, but the speed is high, which requires the bearing to have good wear resistance to avoid damage or wear during use.

4. Low noise, precision bearings are generally used in more sophisticated equipment, and the working environment of these equipment is not harsh compared to other bearings, so the bearings must remain relatively quiet under high-speed operating conditions, that is, low noise. This requires consideration of factors such as friction and lubrication during design.

High-precision bearings are not only manifested in the high speed of the bearing, the speed can meet the requirements, but the low rigidity of the bearing is easy to deform, and the noise is large, which determines that the bearing is not a qualified precision bearing. Therefore, Luoyang FV Bearing will fully consider all factors of the bearing during the design and manufacturing stages, and produce the most perfect bearing to provide customers with the perfect solution.
