Joint bearing is a special structure of the sliding bearing. Simpler structure than the sliding bearing, mainly with an inner and outer sphere within a sphere of outer form, so it can withstand greater load. According to its different types and structures, can bear radial load, axial to load or radial, axial joint load simultaneously. Joint bearings are generally used for lower swing speed of movement (that is, angular motion), as sliding surface for the spherical shape, can also be tilted at an angle within the movement (that is,aligning movement). when the supporting shaft and axle shell holes degree is large, it can still work properly. Joint bearings introduction: 1. Joint bearing is a kind of special structure of sliding bearings. 2.
