Bearings • Spherical Bearings
Spherical bearings are self-aligning bearings designed to manage high radial loads when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present. The bearings are able to handle high loads because they utilize two rows of rollers that are thicker in the middle and thinner at the ends. The bearings also have higher friction than a comparable ball bearing, as different parts of the spherical rollers run at different speeds. Spherical roller bearings can feature brass cage or steel cage, and can be window type or finger type. Some can also handle axial loads.

Timken manufactures spherical plain bearings that carry a high capacity of radial and axial loads in a small envelope due to a large contact area. Timken offers radial spherical plain bearings, radial spherical plain bearings with lip seals, and angular contact thrust spherical bearings that feature lubricating holes and grooves in the outer ring. Other products available include ball, roller and high performance bearings. Timken also manufactures their line of Fafnir ball, angular contact and ceramic bearings.
PSL is a manufacturer of double row spherical roller bearings that can handle heavy radial loads and axial loads in both directions. The outer ring raceway's spherical shape enables mutual alignment in operation and secures uniform load distribution on the rolling elements. Other types of bearing products offered include bearing rollers, all types of roller bearings, and thrust ball bearings.
