SELF ALIGNING BALL BEARINGS INTRODUCTION
self-aligning ball bearings have spherical raceways on the outer ring and double raceways on the inner ring. This type of bearing has self-aligning performance. Therefore, when the bearing is subjected to a load and is bent or the axis of the inner ring is inclined relative to the axis of the outer ring due to processing errors or installation errors, the normal operation of the machine can still be ensured. Self-aligning ball bearings are mainly used to bear radial loads, but they can also bear certain axial loads while bearing radial loads, but they cannot bear pure axial loads.
