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.

Ritbearing Corporation manufactures spherical roller bearings. Features include operation in harsh environments, self aligning characteristics, suitable for applications with large radial loads, and can carry small amounts of axial loads in both directions. Ritbearing spherical roller bearings are primarily supplied with either a steel cage or a machined brass cage. Other bearing products offered include angular contact ball bearings, cam and roller bearings, and self aligning ball bearings.
SNR Industry is a manufacturer of premium spherical roller bearings. These bearings can sustain very high radial loads and moderate axial loads. Their EA Series with steel cage bearings is for general high temperature applications. SNR's EF800 Series employs a solid cage for high vibration applications. Other applications for SNR spherical roller bearings include large industrial fans and large reduction gears. Ball, roller and thrust bearings are also available.
