Classification of Joint Bearings

Joint bearings are mainly divided into: centrifugal bearings, angular contact joint bearings, thrust joint bearings, rod end joint bearings.

First. Joint bearings according to different classification methods, according to the direction of the load can withstand or nominal contact angle is different, divided into the following categories.

1. Centrino joint bearings - used to withstand radial loads, its nominal contact angle from 0 degrees to 45 degrees, according to its nominal contact angle, can be divided into:

a. Radial contact to the centripetal joint bearing - the nominal contact angle is 0 degrees centripetal joint bearing, suitable for carrying radial load. But it can also withstand radial loads while not bearing a small axial load.

b. Angle contact to the centripetal joint bearing - the nominal contact angle is greater than 0 degrees, but less than or equal to 45 degrees centripetal joint bearings, can withstand the radial load and axial load at the same time the joint load.

Second. Thrust joint bearings - used to withstand axial load, its nominal contact angle is greater than 45 degrees to 90 degrees, according to the nominal contact angle of different, can be divided into:

a. Axial contact thrust joint bearings - the nominal contact angle is 90 degrees thrust joint bearings, suitable for carrying pure axial load.

b. Angle contact thrust joint bearings - nominal contact angle is greater than 45 degrees, but less than 90 degrees thrust joint bearings, suitable for axial load, but also can withstand the combined load (at this time its radial load value must not be greater than 0.5 times the axial load).

2. Joint bearings are divided into:

a. The whole outer ring joint bearing;

b. Double-semiring joint bearings;

c. single seam outer ring joint bearings;

d. Double seam outer ring (cut outer ring) joint bearings.

Third. Joint bearings are divided into:

a. General joint bearings;

b. Rod end joint bearings.

Forth. Joint bearings are divided into:

a. Non-self-lubricating joint bearings;

b. Self-lubricating joint bearings.

Fifth. Joint bearings are divided into:

a. centripetal bearings;

b. Angle contact joint bearings;

c. Thrust joint bearings;

d. Rod end joint bearings.
