Spherical Plain BearingIt is a specially designed sliding bearing. Its layout is simpler than that of rolling bearings. It mainly consists of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand larger loads. Depending on its type and layout, it can withstand radial loads, axial loads, or combined loads of radial and axial directions.

Joint bearings are generally used for low-speed shaking motion, that is, angular motion. Due to the spherical sliding surface, they can also perform tilting motion within a certain angle range, that is, centering motion. Even when the supporting shaft and the shaft housing hole have different degrees of concentricity, they can still operate normally.

Joint bearings bear loads in the direction of their load-bearing capacity. According to the nominal contact angle and layout, it can be divided into radial joint bearings. Angular contact joint bearings. Thrust joint bearings and rod end joint bearings. The nominal contact angle of the radial joint bearing (GE type) is 0 degrees, which is suitable for bearing radial loads and small axial loads. Angular contact joint bearings, GAC type, are divided into two types: angular contact radial joint bearings and angular contact thrust joint bearings.

The nominal contact angle of angular contact radial joint bearings is greater than 0 degrees but less than or equal to 30 degrees, and they are accustomed to bearing a combined load of radial and axial loads; The nominal contact angle of angular contact thrust joint bearings is greater than 30 degrees and less than 90 degrees, which is suitable for bearing axial loads and can also withstand combined loads. However, at this moment, its radial load must not exceed 0.5 times the axial load. The nominal contact angle of the thrust joint bearing (GX) is 90 degrees, which is suitable for bearing axial loads and cannot withstand radial loads. Rod end joint bearings are suitable for bearing axial loads with small radial loads, generally less than or equal to 0.2 times the radial load.
