Joint bearing structure

- May 08, 2019-

The structure of the joint bearing is simpler than that of the rolling bearing, and it mainly consists of an inner ring having an outer spherical surface and an outer ring having an inner spherical surface.


Joint bearings are generally used for low-speed oscillating motion (ie angular motion). Since the sliding surface is spherical, it can also be tilted in a certain range of angles (ie, aligning motion), and the support shaft is not concentric with the shaft hole. When the degree is large, it still works normally.
