Spherical Roller Bearings - Bore Diameter 50mm Or Less, High Load Capacity, Self-aligning Design, Vibration Resistant

Our Spherical roller bearings consist of an outer ring having a continuous spherical raceway centered within & two rows of barrel-shaped rollers operating in separate raceways ground into the inner ring with a center rib to guide the rollers. This type of bearing has self-aligning nature; so, it can be used in cases where misalignment between the inner & outer ring occur from shaft mounting errors of shaft deflections.

The allowable misalignment for these bearings, being varied due to the dimensional series & loading conditions, is about 0.009 radian (0.5 degree) for ordinary loads (equivalent to 0.09 Cr). for light loads, this angle can be up to 0.035 radians (2 degree).

These bearings have a large capacity for radial loads, axial loads in either direction, & combinations of these loads. They are also suited for applications where vibration & / or impact forces are encountered.

The design of spherical roller bearings are standardized so that the center roller guide rib comes standard with the inner ring as one united inner ring. Smaller bearings(bore diameter of 50 mm or less) of bearing series 222, 213 & 223 come in the design. This design uses a separable guide ring between the two rows of roller & is specified by attaching the suffix C at the end of the basic number. For the bearings of series 213 (bore diameter of 55 mm or more) the guide ring between the rollers is located on the raceway of the outer ring.
