Here at Townsend Bearings we are industrial and agricultural suppliers of a wide range of single and double row roller bearings in both metric and imperial sizes.
Roller bearings use rollers instead of balls in their construction enabling them to take a much greater load than their ball bearing equivalent.
The two most common types of roller bearings are spherical roller bearings and cylindrical roller bearings.
Spherical roller bearings have two rows of rollers, slightly barrel-shaped, that run in their own tracks on the inner ring, but have a shared spherical raceway on the outer ring. This allows them to be self-aligning, taking up any misalignment that might be present in a shaft. The spherical roller bearings are available (with a few exceptions) with a parallel bore and a tapered bore, the latter to be fitted onto a shaft using an adapter sleeve and locknuts. Spherical roller bearings are most commonly used in conjunction with plummer block style bearing housings.
In a cylindrical roller bearing the rollers are guided by shoulders on the inner or outer ring, or both. If there are no shoulders present on a ring, then the ring can be separated from the rest of the bearing to aid assembly, by either locating the outer ring into a bore prior to assembly, or the inner ring onto a shaft. The rollers themselves are parallel, and the bearing is particularly suitable for high speeds and heavy radial loads.
