Self-Aligning Bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring.  This type of ball bearing is recommended when alignment of the shaft and housing is difficult, and the shaft may flex.  Unlike a single row or double row ball bearing, the self-aligning bearing’s performance will not be affected by misalignment.  Therefore, they are particularly suitable for application where misalignment can arise from errors in mounting or shaft deflection inherent in the application. These bearings are made with seal or without seal.
