ABSTRACT:
A plastic bearing and plastic conveyor guide track include a lubricating site formed by an oil saturated polymer. In a plastic bearing, a lubricating strip resides in contact with a shaft rotatably supported by the shaft. In the guide track, oil saturated polymer elements are inserted prior to machining and are exposed at selected guide features during machining. Enhanced lubrication results without sacrificing the load bearing capabilities of the plastic material forming the bearing or guide track body.
