Spherical plain bearing

The structure of the Spherical plain bearing is a combination of an inner ring having an outer spherical surface and an outer ring having an inner spherical surface. Joint bearings are commonly used for low-speed oscillating motion (ie angular motion). Since the sliding surface is spherical, it can also be tilted within a certain angular range (ie, aligned motion), and the support shaft is not concentric with the shaft hole, so it can still work normally when the bearing is displaced.

Manufacturing process of spherical plain bearing

Spherical plain bearing have large sliding contact areas and large inclination angles. Therefore, the surface of spherical plain bearings needs to be treated with special processes such as surface phosphating, galvanizing, chrome plating or outer sliding lining, inserting and spraying. Spherical plain bearings have the characteristics of large bearing capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, lubrication or self-lubrication, and no lubrication. Even if the installation is not correct, the bearings can still work normally.

Application of spherical plain bearings

Spherical plain bearing consist of an inner ring and an outer ring with spherical contact faces. Depending on its construction and type, it can withstand radial loads, axial loads or combined loads of radial and axial action. Spherical plain bearings are widely used in low-speed mechanical equipment such as engineering hydraulic cylinders, forging presses, construction machinery, automation equipment, automobile shock absorbers, hydraulic machinery, etc. for swinging, tilting and rotating motion.
