A bearing is a mechanical component used to support shaft rotation, reduce friction, and ensure precise movement of the shaft under load. According to different classification standards, bearings can be divided into the following main types:
Classified by exercise mode:
Rolling bearings: Rolling elements (balls or rollers) roll between the inner and outer rings, such as deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, needle roller bearings, etc.
Sliding bearings: also known as sliding bearings or bushings, where the shaft slides relative to the bearing surface, including radial sliding bearings, thrust sliding bearings, and composite material bearings.
