Plastic Screw Gears material Acetal Acetal is a stable plastic material with inherent self-lubricating properties which can be enhanced with lubricating fillers.

Delrin Delrin can be an engineered plastic material with a good mixture of toughness, stiffness, wear and abrasion level of resistance, and low frictional features.

Nylon Nylon, comprising many grades of polyamides, is a general-purpose material in wide make use of. It is difficult and resistant and has good pressure ratings.

Polycarbonate Polycarbonate is an extremely difficult polymer that 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 Additional unlisted or specific polymers or plastic components.
