Rolling bearing in the use of the process, must be lubricated, the role of lubrication as follows:
1. Reduce the sliding original rub. Rolling bearing although the main friction, but due to manufacturing variations and with the elastic deformation of the parts, often with rolling body and raceway between the rolling body and the cage; cage and the inner and outer rings Between, there is sliding friction. The sliding friction with the speed and load increases, in order to reduce friction and wear, to prevent burns and corrosion, the rolling bearing should have good lubrication.
2. Export the heat generated by the work of the bearing.
3. To prevent the rolling body and the surface of the polished surface and other less corrosive products.
4. As the working temperature increases so that the shaft elongation, easy to make the box or shaft floating bearing axial movement.
5. Fill the gap between the bearing parts, the bearings and moving parts filled with grease, you can prevent dust, moisture and other debris immersed in the bearings, to improve the role of the sealing device.
