Bearing cages for supporting and retaining roller elements in cylindrical roller bearings

A cage assembly for retaining and supporting cylindrical, bearing rollers comprising:

• (a) an annular cage member, the cage member including:
• (1) a straight cylindrical portion having a plurality of pockets formed therein for receiving a plurality of bearing rollers,
• (2) at least one flange provided on one axial end of the cylindrical portion, the flange having an axial outer side face, a radial inside edge face and a radial outer edge,
• (b) at least one plastic retaining member, the roller retaining member comprising:
• (1) an annular ring portion having an annular side face adapted to be contacted by the axial outer side face of the flange,
• (2) an annular fitting face contiguous with the annular side face,
• (3) a plurality of teeth having a radial outer face and a radial inner face, the teeth extending axially inwardly from the ring portion and positioned between adjacent rollers for preventing slipping down or out of any bearing roller, and
• (4) a plurality of lips integrally formed with the ring portion for locking the roller retaining member to the flange,
• each of the teeth having a face extending axially inward from a radial outer tip end and inclining radially inward such that the roller retaining member is coupled to the cage member by pushing the retaining member axially inward from outside the flange of cage member.
