A tolerance ring () for providing an interference fit between inner and outer components () is disclosed. The tolerance ring () comprises a deformable band having a plurality of radially extending projections around its circumference, wherein the projections include a set of axially spaced protuberances () separated by a unformed region () circumferentially adjacent to an axially elongate protuberance (), the axial extent of which spans the axial extent of the set of axially spaced protuberances. This arrangement of protuberances facilitates the transfer of retention force to a component that is composed of a plurality of independent parts, e.g. two or more bearings () separated by a spacer ().

Mounting assembly

A tolerance ring () for providing an interference fit between inner and outer components () is disclosed. The tolerance ring () comprises a deformable band wound to form a first layer () having a plurality of radially extending projections () around its circumference and an unformed second layer () which overlaps with the first layer. The second layer acts as a force diffuser to spread the forces transferred through the projections on to the inner or outer component.
