Drum roller bearings are single row, self-aligning roller bearings. They consist of a solid outer ring with a spherical raceway, a solid inner ring with two retaining edges and a cylindrical or tapered bore, and drum rollers with cages. The bearings are not separable.
Drum roller bearings are particularly suitable where high radial shock loads occur and misalignments must be compensated. See Compensation of misalignments. The axial load carrying capacity is very small
