Grease plays a vital role in bearings. As a lubrication part, it can significantly improve the smooth operation of bearings and effectively extend the service life of bearings. Different brands and working conditions require different greases with different properties. Choosing the right grease is crucial for the long-term use of the bearing.

Bearing lubricating oil is crucial to the performance of wheel hub bearings. It directly affects the wear resistance and service life of the bearings as well as the safety and reliability of the entire vehicle.

When selecting bearing seal materials, factors such as application environment, temperature, pressure, medium properties, etc. need to be considered to ensure that the seal can meet the requirements of actual working conditions. At the same time, it is also necessary to pay attention to the matching between the seal and the bearing to ensure a good sealing effect.

Bearing seal devices can be mainly divided into three types: self-contained seal, external seal and hybrid seal. Each type has its specific design and application.
