Classification of joint bearings
(1) Joint bearings can be divided into centripetal joint bearings, angular contact joint bearings, thrust joint bearings and rod end joint bearings according to the direction of load bearing and nominal contact Angle according to the structural form.
(2) The nominal contact Angle of the centriolar joint bearing (GE type) is 0 degrees, which is suitable for bearing radial load and small axial load.
(3) angular contact joint bearings (GAC type) are divided into angular contact centripetal joint bearings and angular contact thrust joint bearings.
(1) The nominal contact Angle of angular contact centriolar joint bearing is greater than 0 degrees but less than or equal to 30 degrees, which is suitable to bear the joint load of radial load and axial load at the same time;
(2) The nominal contact Angle of angular contact thrust joint bearing is greater than 30 degrees and less than 90 degrees, which is suitable for bearing axial load and joint load, but at this time its radial load shall not be greater than 0.5 times the axial load
