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.
Nylons are typically described according to numbers (6, 66, 11, 12, etc.) which relate to their molecular structures. Although there are many types of Nylon, the two most common available in sheet, rod, and tube are Nylon 6 and Nylon 6/6.
