Abstract
A sleeve bearing assembly and method of construction therefore has an inner portion constructed from a plurality of yarns to provide a journal bearing surface for receipt of a journal for relative movement therein and an elastic outer portion injection molded at least partially about the inner portion. The plurality of yarns are woven together with at least some of the yarns being woven in a warp direction corresponding to a length of the journal bearing surface and in a weft direction corresponding to a circumferential direction of the journal bearing surface to form a backing of the inner portion. At least one of the plurality of yarns is provided as a self-lubricating yarn woven with the backing in a weft direction to substantially form the bearing surface radially inwardly of the backing.
