SB bearing is locked with set screw on inner ring. SA bearing is locked by set screw on eccentric collar.
Insert bearings (SB bearing) are form changed deep groove ball bearing featured spherical outer diameter surface. It can be inserted into spherical concave of bearing housing for self-aligning effect. Though the basic performance similar to deep groove ball bearing, it is usually used in machinery with low requirements of mounting accuracy. For example, the axles of bearing and housing bores are misaligned or long through shaft with large deflection.
SB Bearing can be used with many Pillow Blocks, 2-Bolt Flanges, 3-Bolt Flanges, 4-Bolt Flanges, Take up units , etc. Saving money for replacing the insert bearing instead of replacing the whole unit.
SB bearing are usually used with pressed steel housing and suitable for shafts with shoulder or where with limited installation space. These bearing are popular in countries like USA, UK, France, Germany, etc.
