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 a self-aligning nature, so, it can be used in cases where misalignment between the inner and outer ring occur from shaft mounting errors or shaft deflections.
These bearings have a large capacity for radial loads, axial loads in either direction, and combinations of these loads. They are also suited for applications where vibration and/or impact forces are encountered.
