The outer spherical bearing is a bearing unit that combines a rolling bearing and a bearing seat. Most of the outer spherical bearings are made of a spherical outer diameter, and are installed together with a bearing seat with a spherical inner hole. The structure is diverse, and the versatility and interchangeability are good.
The bearing seat is generally formed by casting. Commonly used seats include vertical seat (P), square seat (F), boss square seat (FS), convex seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. (T).
Outer spherical bearings are preferentially suitable for occasions that require simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.
