Spherical Plain Bearings Features


The structure of spherical plain bearing is simpler than that of rolling bearing, which is mainly composed of an inner ring with outer sphere and an outer ring with inner sphere.The joint bearing is generally used for the low speed swing motion (that is, angular motion), because the sliding surface is spherical shape, can also be in a certain Angle range for tilt motion (that is, centering movement), in the support shaft and shaft shell hole is not concentricity is large, still can work normally.

The spherical plain bearing can bear heavy load.According to its different types and structures, it can bear radial load, axial load or combined load in both radial and axial directions.Since the outer surface of the inner ring is lined with composite materials, the bearing can generate self-lubrication in operation.Generally used for low speed swing motion, and low speed rotation, but also in a certain Angle range for oblique movement, when the supporting shaft and shaft shell hole is not concentric, still can work normally.Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
