ABSTRACT:
An adaptor for use with an inner bearing ring having a cylindrical bore. The adaptor comprises a tubular portion having a cylindrical outer surface adapted to be received within the inner bearing ring cylindrical bore and a non-cylindrical inner surface adapted to receive a non-cylindrical shaft. A plurality of foldable tabs are distributed along the circumference of the ends of the adaptor. The foldable tabs have a uniform thickness in the axial direction and are directed substantially radially outwardly from the cylindrical outer surface of the tubular portion and are angled axially inwardly. The tubular portion and foldable tabs are formed integrally of a resilient material such that the foldable tabs transiently fold to permit insertion of the adaptor into the bearing ring cylindrical bore and engage end surfaces of the bearing ring to retain the adaptor in the inner bearing ring after insertion.
