Spherical Plain Bearings Characteristics
Spherical Plain Bearings (also known as “Spherical Plane Bearings” "Spherical Ball Bushing Bearings" and “Ball Bushings”) have an inner ring with a sphere convex outside surface and an outer ring with a correspondingly sphere, but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to accommodate, or where oscillating or recurrent tilting movements must be permitted at relatively slow sliding speeds.
AST’s spherical plain bearings are divided into two main categories based upon the need and ability for lubrication. Click on any of the two below to read more about them:
