- PA Polyamide Type 6, 6/6 & Other Types
| | | - Nylon is one of the most widely used plastics in the world, especially as a bearing and wear material. Nylons are frequently used as replacements for bronze, brass, aluminum, steel and other metals, as well as other plastics, wood, and rubber. The most common types include Type 6/6 extruded and Type 6 cast, which are available in sheet, rod, tube, film, custom profile and parts depending on the grade. Many formulations are available with different additives to enhance wear properties, stiffness, lower friction and improve other properties. Nylons offer extremely good wear resistance, coupled with high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, nylons can withstand sustained contact with a wide variety of chemicals, alkalies, dilute acids or oxidizing agents.
Another important factor, both economically and mechanically, is the relative light weight of nylon -- approximately 1/8 the weight of bronze, 1/7 the weight of cast iron, and 1/2 the weight of aluminum -- which reduces both the inertial and static loads and eases the handling of large components during maintenance or replacement procedures.

- Polyester, Marine Grade & Vinyl Ester Resin Textile Laminate
| | - 200 F / 93 F to 400 F / 204 C
| - CIP Composite™ are laminated polymer materials made by impregnating textile with thermoset resins. The high strength and other physical properties of CIP materials make them ideal bearing materials to replace bronze in high load – low speed applications. CIP Composites offer design engineers an attractive, cost effective alternative to the traditional materials used for bushings, bearings, wear pads, and thrust washers, such as bronze or nylon. CIP Composites are only 1/6 the weight of steel, easily machined, have good dimensional stability and do not contain harmful or toxic materials. CIP grades are available in different resin and reinforcement options that can handle temperatures from -40 F to 400 F depending on the CIP Grade.
