Self-Aligning Ball
-
The inner ring has two raceways, while the outer ring has a spherical raceway with the curvature center of the spherical surface aligned with the center of the bearing. So, the inner ring, ball, and cage can tilt relatively freely towards the outer ring. Therefore, the deviation caused by the machining error of the shaft and bearing box can be automatically adjusted.
The inner ring tapered hole bearing can be installed with a locking sleeve.
