Spherical roller bearings utilize asymmetrical spherical or barrel-shaped rollers. These bearings feature two inner ring raceways and a shared spherical outer ring raceway. Typically, they support a rotating shaft passing through the inner ring bore and allow for a certain degree of misalignment (i.e., shaft axis tilting) relative to the outer ring. This misalignment capability is derived from the spherical inner surface of the outer ring and the design of the spherical rollers. Consequently, these bearings are suitable for applications where angular misalignment between the shaft and the housing bore is likely to occur.
