Nylon 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 noise, and decreased wear on mating parts.

Nylon usually refers to the family of plastic known as polyamides (PA), it is an engineering thermoplastic with excellent mechanical properties and is widely used in CNC machining for various industries. Nylon polymers can be mixed with a wide range of additives to achieve different variations, including fibres, fabric, shapes, and films.
