Material Acetal Acetal is definitely a stable plastic material with inherent self-lubricating properties that can be enhanced with lubricating fillers.
Delrin Delrin is an engineered plastic-type with a good mixture of toughness, stiffness, use and abrasion resistance, and low frictional characteristics.
Nylon Nylon, comprising a number of grades of polyamides, is a general-purpose material in wide make use of. It is tough and resistant and offers good pressure ratings.
Polycarbonate Polycarbonate is an extremely hard 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 Other Plastic Screw Gears unlisted or specialized polymers or plastic components.
