Wide range of applications for joint bearings

- May 03, 2019-

The joint bearing is a special type of plain bearing. Its structure is simpler than rolling bearings. It is mainly composed of an outer ring with an inner spherical surface and can withstand large loads. It can withstand radial loads according to the inner ring with outer spherical surface and its different type and structure. Combined load in axial load or in both radial and axial directions.


Generally used for low-speed oscillating motion (ie, angular transport, tilting motion within a certain range of angles (ie, aligning motion), because the sliding surface is spherical), the center of the bearing shaft and the shaft hole are not different. When it is large, it still works.


Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Because the spherical sliding contact area of the joint bearing is large, the inclination angle is large, and because most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying and the like.
