Abstract
Novel, unitary, full complement bearing components are described which comprise a plurality of rolling elements embedded in a solid, self-supporting lubricating matrix with at least one arcuate operative surface of each rolling element exposed for rolling contact with another bearing component, the rolling elememts being in side-by-side contact or only slightly spaced from each other, and the matrix being composed of a gel obtained by thermally curing a mixture of lubricating oil and a high molecular weight polymer, and being capable of exuding lubricating oil under sliding friction in operation after insertion of the bearing component into a bearing structure in a single assembly operation. Full complement as used herein means a cageless rolling element bearing with a maximum number of rolling elements wherein no additional rolling elements can be added to the complement of rolling elements and wherein the rolling elements are in side-by-side relation.
