Spherical plain bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment. AST Bearings offers a complete line of spherical bearings available in inch and metric. These High-Quality Spherical Plain Bearings are suitable for heavy-duty, off-highway vehicles, agricultural equipment, construction and mining and logging equipment, packaging and textile equipment, and robotics.

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.
