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

Delrin Delrin is an engineered plastic-type with a good combination of toughness, stiffness, wear and abrasion level of resistance, and low frictional characteristics.

Nylon Nylon, comprising a number of grades of polyamides, is a general-purpose material in wide use. It is challenging and resistant and offers great pressure Plastic Screw Gears ratings.

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

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