Insert Bearing

Features, Advantages and Applications

Insert bearings, also known as outer spherical bearings, are commonly used rolling bearings. They feature an outer spherical surface on the inner ring, which fits with the housing to provide excellent self-aligning capability and adaptability.

Features：

• Inner ring with spherical outer surface allows automatic adjustment to installation errors;

• Capable of carrying substantial radial loads and certain axial loads;

• Often used with housings to form mounted bearing units with a compact structure.

Advantages:

• Easy to install, typically fixed with set screws or an eccentric locking collar, with simple maintenance;

• Strong self-aligning performance reduces precision requirements during installation;

• Available with multiple sealing options to effectively prevent dust and moisture intrusion, extending service life.

Applications:
Widely used in agricultural machinery, construction machinery, textile equipment, food processing machinery, conveying systems, and various light industrial machines. They are especially suitable for applications with moderate loads that require quick replacement and easy maintenance.
