Joint Bearing GE80ES GE80ET GEEW80

Joint bearing is a kind of special structure of the sliding bearing. The structure of it than rolling bearing is simple, its main is by a insert the inner ring and a inside spherical outer composition, can bear larger load, according to its different types and structure, can bear radial load and axial load or radial, axial and existing joint load. Generally used for speed lower oscillating motion (namely Angle motion), due to the sliding surface for spherical shape, can be in a certain Angle range for inclined movement (namely self-aligning movement), in supporting shaft and shaft shell hole not concentricity is larger, can still work normally.

According to the joint bearing capacity under the direction of the load. Nominal contact Angle according to and structure form, can be divided into to the heart joint bearings, angular contact joint bearing, thrust joint bearing and rod end joint bearing. Centripetal knuckle bearing (GE type) of the nominal contact Angle 0 degrees, suitable for bear radial load and smaller axial load; Angular contact joint bearing (GAC type) and points angular contact to the heart joint bearing and angular contact thrust joint bearing two kinds, angular contact to the heart joint bearing nominal contact Angle is greater than 0 degrees but less than or equal to 30 degrees, adapt to bear radial load and axial load effect at the same time the joint load; Angular contact thrust joint bearing nominal contact Angle is greater than 30 degrees is less than 90 degrees, suitable for bear axial load, it also can bear joint load, but at the moment, the radial load must not be more than 0.5 times of axial load, Thrust joint bearing (GX) nominal contact Angle for 90 degrees, suitable for carry axial load, cannot bear radial load. Rod end joint bearing suitable for bear radial load smaller axial load (usually less than or equal to 0.2 times the radial load)
