Abstract: Disclosed is a bearing race comprising a surface having a plurality of pores formed therein. A lubricant is provided in the pores. The race has a body having a porous volume contiguous with the surface. The surface includes a load bearing zone configured to be in contact with a rolling element of a bearing, the pores being distributed on the surface to provide the lubricant to the load bearing zone.

Abstract: A self-lubricating roller bearing is provided. The roller bearing includes an inner race, an outer race, and a plurality of rollers between the inner and outer races. Each of the inner race and the outer race includes a bearing surface for contact with the rollers. The bearing surface of one or more of the inner race, the outer race, and the rollers has one or more laser hardened areas and one or more non-laser hardened areas arranged in a predetermined pattern. The one or more non-laser hardened areas create dry lubricant for the roller bearing upon wear thereof.

Abstract: A method for manufacturing a seat cushion for a user is provided. The method comprises positioning the user on a test seat, scanning a plurality of pressure points of the user while the user is seated on the test seat, recording the plurality of pressure points to generate a pressure map, and manufacturing, using one of an additive manufacturing process, an additive manufactured tool and a molding process, the seat cushion conforming to the pressure map of the user.
