Description
Spherical Plain Bearing is a kind of silding bearing with special structure. Its structure is easier then roller bearing, which mainly makes up of inner race’s outer track and outer race’s inner track., it can bear bigger load, and according to the different style ng structure, it can bear radial load, axis load or united load. Joint bearing generally uses in undulatory motion with lower speed, because of the sliding surface is spherical, it also can do the slant movement in a range of the angle.
