Plastic Screw Gears material Acetal Acetal is usually a stable plastic-type material with inherent self-lubricating properties that can be improved with lubricating fillers.

Delrin Delrin is an engineered plastic material with a good combination of toughness, stiffness, put on and abrasion resistance, and low frictional features.

Nylon Nylon, comprising several grades of polyamides, is a general-purpose materials in wide make use of. It is challenging and resistant and has good pressure ratings.

Polycarbonate Polycarbonate is an extremely challenging polymer which can be machined to close tolerances. Lubrication is sometimes needed, as the wear properties of polycarbonate are not as good as various other polymers.

Other Plastic Various other unlisted or specialized polymers or plastic components.
