Tapered roller bearings provide a high capacity for radial loads, axial loads and combined loads.When a pure radial load is placed on the bearing, an induced load in the axial direction is also generated.Since the inner and outer rings are separable,each ring can be mounted individually. Tapered roller bearings can be disassembled into subunits, dimensions are standardized in ISO or AFBMA standards,provide interchangeability within each dimensional standard.
