GEZ Series Self-aligning Spherical Plain Bearing GEZ63ES GEZ63ES-2RS
Features of spherical plain bearing
The structure of the spherical plain bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface.
Spherical plain bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range.
Spherical bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. The spherical plain bearing is a spherical sliding bearing, and 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 combined radial and axial loads at the same time.
