It’s not hard to understand why some product designers and engineers would hesitate to use plastic bearings in their designs. After all, they’re probably used to rugged product and subsystem components like bearings being made from alloys such as steel and bronze or they simply don’t think plastics can handle tough applications or extreme environmental conditions.
Why would you use plastic bearings and bushings? Modern plastics may offer advantages over traditional metal applications. Depending on the application, choosing to use plastic over other more traditional materials can offer longer life, reduced maintenance costs and lower energy consumption.
