Introduction to Joint Bearing Products
The structure of joint bearings is simpler compared to rolling bearings, mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface assembled together. Joint bearings are commonly used for low-speed swinging motion (angular motion), with a spherical sliding contact surface that can complete tilting and centering motion within a certain angle range. Even if there is a large concentric deviation between the supporting shaft and the shaft housing hole, they can operate smoothly.
