The difference between high and low speed bearings is mainly reflected in the following aspects:
1. Structure: The main difference between high and low speed bearings is the difference in their internal structures, which are mainly divided according to linear speed rather than rotational speed. Low-speed bearings usually use rolling bearings, while high-speed bearings use sliding bearings.
2. Rotating part: The rotating part of low-speed bearings is usually circular, while the rotating part of high-speed bearings is mainly bearing bushes.
3. Material: High-speed bearings generally use high-hardness steel, which can withstand the pressure caused by higher speeds. Low-speed bearings use relatively common materials because they do not need to bear too much pressure.
4. Purpose: High-speed bearings are often used in situations that require high speeds, such as inside engine transmissions, while low-speed bearings are used in situations that bear larger alternating loads, such as the half-shaft hub bearings of the chassis.
5. Surface smoothness and precision: From the appearance, the surface of high-speed bearings is smoother, the distance between the inner ring and the outer ring is very small, and its accuracy and precision are higher than that of low-speed bearings. In addition, the precision of the steel balls, rollers and raceways of high-speed bearings is also significantly higher than that of low-speed bearings.
There are obvious differences between high and low speed bearings in terms of structure, rotating parts, materials, uses, surface smoothness and accuracy. In actual use, the appropriate bearing type should be selected according to specific needs and conditions.
