Hydraulic cylinder cushion stem with over molded sleeve

A cushion sleeve for a hydraulic cylinder, comprising:

• a metallic inner sleeve including a threaded opening configured to threadingly receive a cushion stem extending from a piston of the hydraulic cylinder;
• a non-metallic over molded outer sleeve surrounding the inner sleeve, the non-metallic outer sleeve having a non-uniform outer diameter;
• a plurality of projections formed on an outer surface of the inner sleeve, and
• a plurality of recesses formed on an inner surface of the outer sleeve and configured to receive respective ones of the plurality of projections.

A hydraulic cylinder, comprising:

• a tube extending from a tube first end to a tube second end;
• a piston disposed in the tube;
• a piston rod attached to the piston and configured for axial movement in the tube;
• a cushion stem extending from the piston;
• a head end cavity disposed adjacent to the tube first end;
• a cushion sleeve disposed on the cushion stem and configured to be received in the head end cavity, the cushion sleeve comprising:
• an inner sleeve including an opening configured to receive the cushion stem and a plurality of circumferential projections formed on and extending radially outward from an outer surface of the inner sleeve;
• and
• an outer sleeve at least partially surrounding the inner sleeve and including a plurality of circumferential recesses formed on an inner surface of the outer sleeve and configured to receive respective ones of the plurality of circumferential projections, the plurality of circumferential recesses extending into a thickness of the outer sleeve from an inner surface of the outer sleeve.
