Spherical Plain Bearings Ge...e

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.

These bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment.


Spherical plain bearings are divided into two main categories based upon the need and ability for lubrication:

1, maintenance-free spherical plain bearings
2, spherical plain bearings requiring maintenance/lubrication

Maintenance required

Sliding contact surfaces: steel/steel.
Material: - outer ring -sae52100, hardened and phosphorized
- inner ring -sae52100, hardened and phosphorized
