Joint bearings and classification Joint bearings are spherical sliding bearings. The basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces.

Depending on its structure and type, it can bear radial load, axial load, or a combined load that acts on both radial and axial directions.

Because the spherical sliding contact area of the spherical plain bearing is large, the inclination angle is large, and also because most of the spherical plain bearing adopts special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying, etc.

Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating without lubricating dirt pollution, and it can work normally even if the installation is misplaced. Therefore, joint bearings are widely used in low-speed swing motion, tilt motion and rotational motion.

It is generally used for low-speed swing motion and low-speed rotation, and can also be tilted within a certain angle range. When the support shaft and the shaft housing hole are not centered, it can still work normally. Self-lubricating joint support is used in water conservancy, professional machinery and other industries.
