Nylon is a strong, stiff engineering plastic with outstanding bearing and wears properties. Nylon is frequently used to replace metal bearings and bushings, often eliminating the need for external lubrication. Other benefits include a reduction in part weight, less operating noise, and decreased wear on mating parts. Nylon is available in a variety of speciality formulations. Molybdenum disulphide-filled and oil-filled nylons have enhanced wear properties, while heat stabilized nylon will withstand higher operating temperatures. For enhanced strength and stiffness, nylon is also available in glass-filled grades. In power transmission applications NYMETALTM billets made with nylon and a metal core combine the performance advantages of nylon and metal into one cohesive unit. The billets can be manufactured into many different components including gears, rollers, sprockets, and augers.
