Axial spherical roller bearings are single row, self-aligning roller bearings. They comprise solid shaft and housing washers and asymmetrical barrel rollers with cages. The cage holds the roller and cage assembly together with the shaft locating washer. The bearings can be dismantled. The parts of the bearings can be fitted separately.

Axial spherical roller bearings can support very high axial loads and permit relatively high speeds. Since the raceways are at an angle to the bearing axis, the bearings can also support radial loads.
