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

Delrin Delrin can be an engineered plastic-type material with a good combination 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 materials in wide make use of. It is tough and resistant and offers good pressure ratings.

Polycarbonate Polycarbonate is an extremely challenging polymer which can be machined to close tolerances. Lubrication is Plastic Screw Gears sometimes needed, as the use properties of polycarbonate aren’t as good as various other polymers.

Other Plastic Other unlisted or specific polymers or plastic components.
