Self-aligning Ball Bearing

45*85*19mm Self-aligning ball bearing

Description：

The self-aligning ball bearing is a type of rolling-element bearing designed to accommodate misalignment between the shaft and the housing. This misalignment can occur due to shaft deflection, mounting errors, or thermal expansion. Self-aligning ball bearings consist of two rows of balls, a common spherical raceway in the outer ring, and two deep raceways in the inner ring. This construction allows the bearing to align itself automatically with the shaft and housing, compensating for angular misalignment.
