spherical bearings have an inner ring with a convex sphered outside surface and an outer ring with a correspondingly sphered but concave inner surface. They are particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated or where recurrent tilting or oscillating movements must be performed at relatively slow sliding velocities. Spherical bearings are produced with different sliding contact surfaces combinations, the sliding surfaces of the inner and outer rings are made of different materials. There are two main groups: steel-on-steel [spherical bearings] and maintenance-free spherical bearings. Maintenance-free spherical bearings incorporate special sliding layers or liners of wear-resistant materials. They are used for applications where maintenance-free operation is required, where the use for application is required, where the use of lubricants is not permitted (e.g. in the food industry), or where the application is such that under the actual operating conditions lubrication is inadequate or even lacking, making the use of steel-on-steel bearings inadvisable. Maintenance-free bearings are primarily intended for the accommodation of heavy loads acting in a constant direction. They have only limited ability to take up alternating loads. 

spherical bearings and rod ends bearing have a variety of designs and different sliding contact surface combinations. Each design and conbination has unique performance,enable it suitable for certain applications.

Including the following types:

Need to be maintained joint bearing

Maintenance-free Spherical bearings

Need to maintain the rod ends bearing

Maintenance-free rod ends bearing

spherical 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 bearings are suitable for heavy-duty, off-highway vehicles, agricultural equipment, construction and mining and logging equipment, packaging and textile equipment, and robotics. The plain skf 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 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 timken 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.
