Abstract
A hybrid bearing cylinder having a composite sleeve and a metallic jacket positioned around the composite sleeve and secured thereto. The hybrid bearing cylinder is adapted to be secured to metallic cylinder end caps by threading, welding, swaging or other metal attachment methods.
Claims10
A hybrid bearing cylinder comprising
- a composite sleeve having a continuous inner bearing surface and an outer surface, the inner bearing surface defining a primary bearing direction along an axis of the cylinder,
- a resin matrix composed of a resin material, the resin material at least partially at the inner bearing surface,
- a filament material embedded within the resin matrix,
- a jacket positioned around the composite sleeve and having a inner surface that is positioned to lie near the outer surface of the composite cylinder, wherein the ends of the jacket extend further than the ends of the composite sleeve so that the jacket can be coupled with an end cap.
