Product Introduction

Self aligning ball bearings have two rows of spherical rolling elements, with a shared spherical raceway on the outer ring and two deep groove continuous uninterrupted raceways on the inner ring. They can be open or sealed. This type of bearing allows for significant angular displacement of the shaft relative to the bearing seat, such as angular displacement caused by shaft deflection.
