Rod ends bearing is a kind of special structure of sliding bearing. It is simple in structure than the rolling bearing, which is mainly composed of a spherical inner ring and a spherical outer ring, can bear the larger load, according to the different types and structures, can be combined load to bear radial load, axial load, and radial, axial exist at the same time.
Spherical plain bearings have an inner ring with a sphered convex outside surface and an outer ring with a correspondingly sphered out concave inside surface. The design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be permitted ar relatively slow sliding speeds.
