Spherical Roller Bearing, the raceway of outer ring is designed to have a spherical profile, whose centre coincides with the bearing centre point. This type of bearing is self-aligning type, hence can be used for applications where a misalignment of shaft may arise either due to an erroneous mounting or due to shaft deflections. The outer ring generally has lubrication holes and grooves. These bearings are suitable for very high radial impact load applications, and a moderately high level of bi-directional axial load.
