Self-Aligning Ball Bearing 2216C3 80×140×33mm Double Row for Electric Motors

Self-Aligning Ball Bearing 2216C3 80*140*33mm Double Row for Electric Motors

The 2216C3 Double-Row Self-Aligning Ball Bearing is engineered with a cylindrical bore and a common sphered raceway in the outer ring. This unique structural configuration allows the inner ring and ball assembly to swivel freely, automatically compensating for shaft deflection or housing misalignment. It is widely deployed in high-speed, light-to-medium load applications where installation alignment errors are common.
