Rolling bearings compared with sliding bearings, it has the following advantages

Rolling bearings compared with sliding bearings, it has the following advantages:
1. Rolling bearings friction coefficient than the slide bearings, high transmission efficiency. General Bearing friction coefficient is 0.08-0.12, and only Rolling friction coefficient 0.001-0.005;2. Rolling has achieved standardization, serialization, universal, suitable for mass production and supply, use and maintenance is very convenient;
3. Rolling bearing steel manufacturing and after heat treatment, therefore, bearing not only has high mechanical properties and long life, and can save manufacturing sliding bearings used in more expensive colored Metal;
4. Internal bearing clearance is small, high precision of the parts, and therefore, higher running accuracy. At the same time, it can increase the rigidity of the bearing by preloaded approach. This high precision bearings is very important;
5. Some rolling bearings can support radial load and axial load, it is possible to simplify the bearing support structure;
6. Due to the high Rolling transmission efficiency, less heat, and therefore, can reduce oil consumption, lubrication maintenance relatively easy;
7. Rolling can be easily applied to any position of the shaft space.
