Plastic antifriction bearing cage

A two piece, snap assembled bearing cage of molded plastic construction comprising:

• a first piece having a ring portion,
• a plurality of circumferentially spaced finger portions extending axially from said ring portion and having axial end faces at the free end thereof defining a plane parallel to said ring portion,
• a shank portion extending axially from the axial end face of a number of said plurality of finger portions,
• each of said shank portions having a radially flexible end portion having a radial projection which is spaced from the axial end face of its associated finger portion and has a retention face parallel to said plane,
• said first piece having an axial groove extending through each of said number of finger portions and said ring portion in axial alignment with said radial projection, and exposing the entire retention face thereof to the remote end of the first piece to facilitate molding,
• a second piece comprising a second ring portion having said number of circumferentially spaced holes respectively receiving said shank portions of said first piece,
• each of said holes having a radial enlargment extending from one end forming an internal perpendicular radial shoulder engaging the retention face of the radial projection of the shank portion received therein.

A two piece, snap assembled bearing cage of molded plastic construction comprising:

• a first piece having an annular ring portion,
• a plurality of circumferentially spaced finger portions extending axially from said ring portion and
• a generally rectangular shank portion extending axially from an axial end face of each of said plurality of finger portions,
• each of said shank portions having inner and outer radial projections at an end portion thereof spaced from the axial end face of its associated finger portion,
• said end portion having a circumferential slot for radial flexibility,
• said first piece having inner and outer axial grooves extending through each of said finger portions and said ring portion in axial alignment with inner and outer radial projections respectively and
• a second piece comprising a second annular ring portion having said plurality of circumferentially spaced generally rectangular holes respectively receiving said shank portions of said first piece,
• each of said holes having a radial enlargement at one end forming inner and outer radial shoulders respectively engaging the inner and outer radial projections of the shank portion received therein.
