Unmodified nylon is very strong, rigid, and has one of the highest melting points. It is commonly specified for screw machined electrical insulators and food contact parts. It is a strong, stiff engineering plastic with outstanding bearing and wear 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 noice, and decreased wear on mating parts. It has good chemical resistance and is easy to fabricte and machine. Nylon is widely used for bearings and bushings, gears, wear pads, packaging machinery parts, food processing machinery parts, wheels, rollers, seals and gaskets.
