Spherical Plain Bearings

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 with relatively slow sliding speeds. The most common applications are the mining and construction industries.
