Abstract
A light-weight bearing component for sliding or rolling engagement with a mating surface includes a core lattice structure that has a plurality of support members interconnected with one another and a plurality of spaces located between the support members. The bearing component includes a cover that has an interior surface and an exterior surface. The cover extends over a portion of or all of the core lattice structure.
Claims19
A bearing component for sliding or rolling engagement with a mating surface, the bearing component comprising:
- a core lattice structure having a plurality of support members interconnected with one another at reinforcing member sites which comprise fiber strands, and a plurality of spaces located between the support members;
- a cover having an interior surface and an exterior surface, the cover extending over at least a portion of the core lattice structure;
- and
- a surface lattice structure extending from the exterior surface of the cover, wherein the surface lattice structure is integrally formed with the cover.

A bearing assembly comprising:
- an outer member bearing component;
- an inner member bearing component disposed partially in the outer member bearing component, the inner member bearing component and the outer member bearing component being rotatable with respect to each other;
- a first core lattice structure having a plurality of first support members interconnected with one another and a plurality of first spaces located between the first support members;
- the outer member bearing component having a first cover having a first exterior surface, the first cover extending over at least a portion of the first core lattice structure;
- a second core lattice structure having a plurality of second support members interconnected with one another and a plurality of second spaces located between the second support members;
- the inner member bearing component having a second cover having a second exterior surface, the second cover extending over at least a portion of the second core lattice structure;
- a first surface lattice structure extending from the first exterior surface of the first cover, wherein the first surface lattice structure is formed integrally with the first cover;
- and
- a second surface lattice structure extending from the second exterior surface of the second cover, wherein the second surface lattice structure is formed integrally with the second cover.
