Spherical roller bearings (SRB) or self-aligning roller bearings consist of a locking feature. An outer ring. And an inner ring which is enclosed by the former in the axial direction. These bearings permit angular rotation to a central point in two orthogonal directions and support a rotating shaft in the bore of the inner ring which must move not only rotationally but to a certain angle.
Most of these bearings have an outer raceway that is a portion of a sphere making them internally self-aligning. Each roller has a curved form correctly angled to the rotation’s direction which conforms closely to the inner and outer raceways. The housing gives this type of bearing a high radial load-carrying capacity.
