Spherical plain bearing is a spherical sliding bearing. Its basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. Spherical plain bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand large loads. According to their different types and structures, they can bear radial load, axial load or combined load of radial and axial.

Scope of application

It has large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self centering, good lubrication or self lubrication without lubricating dirt pollution. It can work normally even if the installation is misplaced. Therefore, spherical plain bearings are widely used for low speed oscillating, tilting and rotating motions.
