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. Both under the harshest of operating conditions. For example in gearboxes, calenders, engines in marine applications and rudder engines, lifting gear, construction machinery and rolling mills.
