Material Acetal Acetal is certainly a stable plastic material with inherent self-lubricating properties that can be enhanced with lubricating fillers.
Delrin Delrin is an engineered plastic-type material with a good mixture of toughness, stiffness, put on and abrasion resistance, and low frictional characteristics.
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.
Plastic Screw Gears Polycarbonate Polycarbonate is an extremely challenging polymer that can be machined to close tolerances. Lubrication may also be needed, as the use properties of polycarbonate are not as good as some other polymers.
Other Plastic Various other unlisted or specific polymers or plastic materials.
