Nylon 6/6 is the extrusion grade of the Nylon family of solid polymer shapes. It has been commercially available since 1948; developed by Dupont. Nylon is well known for excellent toughness, low coefficient of friction and good abrasion resistance making it an ideal replacement for a wide variety of materials from metal to rubber. Using Nylon 6/6 reduces lubrication requirements, eliminates galling, and corrosion. Low cost combined with improved wear resistance makes Nylon 6/6 an excellent choice for many bearing and wear components.
Nylon 6/6 is easily fabricated into precision parts using standard metalworking equipment. Tolerances of +/-.002 are easily achieved with experience. It is available in a broad variety of shapes and sizes. Rod stock normally comes ground to size making turning easier. Both extruded and cast grades of nylon are available with a variety of fillers to meet specific application demands.
Several manufacturers offer varying grades and filled versions thereof by the names of Tecamid® and Nylatron®, commercially available to accommodate specific applications. Solid lubricants such as mineral oil, , graphite, PTFE, and MoS2 provide lower friction, while reinforcing agent such as carbon fiber, Kevlar®, and glass provide higher levels of strength and dimensional stability.
