Material Acetal Acetal is a stable plastic material with inherent self-lubricating Plastic Screw Gears properties which can be enhanced 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 difficult and resistant and has great pressure ratings.

Polycarbonate Polycarbonate is an extremely difficult polymer which can be machined to close tolerances. Lubrication may also be needed, as the wear properties of polycarbonate are not as good as some other polymers.

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