A bearing construction and method which involves the casting of a piston (22) or cylinder (23) where the bearings (40) or bushings (41) are formed in place. In preferred constructions, the bearings (40) or bushings (41) are solid bronze rod rings held in position on a fixture over which the construction material is poured so that only selected ring portions such as the outer or inner diameters, are exposed beyond the periphery of the construction material. After hardening, the exposed ring portions of the rods are milled or otherwise reduced until the rods are coextensive with the peripheral surface of the construction material. |
