Spherical Bearings – Accommodating Misalignment

October 16, 2015 by Christine Berlly

self-aligning-double-row-ball-bearingsSpherical bearings are available is a variety of types to accommodate a wide range of applications. What all of them have in common is the ability to accommodate misalignment from mounting or shaft deflection.

Regardless of the type of spherical bearing, they all share a common working principal. All varieties have outer rings that with concave (spherical) inner raceways. The inner rings similarly have convex outer raceways (or rolling elements that create a matching convex sliding surface).

What separates the various types of spherical bearings is the design of their sliding surface. Some are ring-to-ring (such as spherical plain bearings and rod ends) while others use rolling elements such as balls or rollers between the inner and outer rings.

Selecting the correct spherical bearing requires detailed knowledge of the application requirements and experience with bearing technology. AST’s team of tribologists are available to provide guidance to make the selection process as simple as possible. Click here to contact us for more information on spherical bearings or any products in our 10,000+ product catalogue.
