摘要

A COMPOSITE BEARING WITH METAL HOUSING HAVING A BORE, WITH A TUBULAR PLASTIC INSERT THEREIN An improved bearing for supporting a bi-fold door member. The bearing is formed from a block of high molecular weight polymer material having a bore extending from its top surface to its bottom surface. The bore is configured to tightly receive a shaft. The bearing supports the door and is rotatably slidable with respect to the shaft as the door member is opened and closed.
