Barrel roller bearings are single-row self-aligning roller bearings. Because of their hollow-ball raceway in the outer ring and the symmetrical spherical roller, the roller assembly can adjust itself when there are misalignments or shaft deflections. Barrel roller bearings are particularly suited for bearings which have to absorb high, impact loadings and where alignment errors must be corrected. They have a low axial load capacity.
