Featuring two angled rows of rollers that glide between a concave outer raceway on the outer ring and two inner-ring raceways inclined at an angle to the bearing's axis, spherical roller bearings can support heavy radial loads (where the load is perpendicular to the shaft) and moderate axial, or thrust, loads (where the load is parallel to the shaft) in both directions. The slightly rounded profile of the rollers and the bearing's angled inner raceways make spherical roller bearings less likely to become misaligned on the shaft than cylindrical roller bearings, and allows them to compensate for shaft deflection in applications with heavy shock loads.
Roller bearings use cylindrical rolling elements that distribute loads over a wide surface area, which allows roller bearings to tolerate higher loads than ball bearings. To ensure proper functioning, bearings should be lubricated regularly.
Use these bearings for a wide variety of standard applications.
