Spherical Plain Bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment. SRG Bearings offers a complete line of Spherical Plain Bearings available in inch and metric. These High-Quality Spherical Plain Bearings are suitable for heavy-duty, off-highway vehicles,agriculturalequipment, construction and mining and logging equipment, packaging and textile equipment, and robotics. The plain bearings come in standard industrial bore sizes from 0.5" to 12" inches, as well as metric sizes from as small as 4 to 300 mm.  Custom sizes can also be ordered.

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.

        In addition to ball and roller bearings SKF also produces a comprehensive range of spherical plain bearings and rod ends and has a choice of materials for plain and flanged bushings as well as thrust washers.

        Spherical plain bearings and rod ends are produced in various designs and with various 

combinations of sliding contact surfaces. Each design and combination has characteristic properties which make it particularly suitable for certain applications.

        To select a certain bearing type and to establish the requisite bearing size, the main 

factors which have to be considered are the loads, the load carrying capacity of the bearing and the expected service life. The same is true when selecting a rod end.
