Material Acetal Acetal is a stable plastic-type material with inherent self-lubricating properties which can be enhanced with lubricating fillers.
Plastic Screw Gears Delrin Delrin is an engineered plastic-type with a good mixture of toughness, stiffness, put on and abrasion level of resistance, and low frictional features.
Nylon Nylon, comprising many grades of polyamides, is a general-purpose material in wide use. It is tough and resistant and provides good pressure ratings.
Polycarbonate Polycarbonate is an extremely hard polymer that can be machined to close tolerances. Lubrication may also be needed, as the put on properties of polycarbonate aren’t as good as various other polymers.
Other Plastic Various other unlisted or specialized polymers or plastic components.
