Single row spherical bearings are self-aligning roller bearings. This means that single row spherical bearings can align themselves so that no stress is ever exerted on the shaft. Spherical bearings also have a solid outer ring and ball-shaped races. The inner ring has ribs. Spherical bearings can have a cylindrical or conical bore. The rollers of a spherical bearing are barrel-shaped and are guided in a cage. It is not possible to remove a spherical bearing. Spherical bearings are suitable for radial loads with significant misalignments. Axial loads are low for spherical bearings, but higher than for ball bearings, for example.
