A dispersion of hard, wear-resistant particles (21) such as aluminum oxide is embedded within a shaft-engaging surface (11) of a bearing (13) such that the service life of a shaft and bearing assembly is extended. The relatively hard aluminum oxide particles exert a polishing action on the shaft surface to improve the wear resistance and seizure resistance of the bearing and shaft system. A tumbling barrel (25), vibratory bowl, air jet (40), brush or similar apparatus can be used to apply and embed tumbling media particles within the shaft-engaging surface. During the application period, aluminum oxide particles are transferred to the bearing member surfaces by the sliding, rubbing contact between the abrasive bodies and the individual bearing members. |
