Case Study

Plastic Vs Steel

Product Integration: A plastic bearing can be mounted into other components or parts such as plastic wheels, pulleys or housings. In certain design concepts, seamless integration can be achieved where the bearing will have the pulley profile as the outer ring, and the shaft or a fixing clip replaces the inner ring . This integration lowers assembly time and also results in utilization of fewer parts, increasing affordability.
