Customized leadscrew nuts for highend motion-control applications are made from polymers and can be molded into any shape or with complex features. The standard material is self-lubricating polyacetal, which offers dimensional stability, good tensile strength, and is easy to machine. The nuts are impregnated with TFE for a permanent, self-lubricating thread contact surface.
Besides polyacetal, the nuts can be made from many alternative plastics, including PEEK, polyester, Torlon PAI (polyamide-imides), Vespel polyimide-based resin, PVDF, Ertalyte PET-P (polyethylene terephthalate), and customer-supplied specialty materials, as well as from bronze, brass, and stainless steel.
Thread diameters range from 2 (5/64 in.) up to 24 mm (15/16 in.). Thread leads are available from 0.30 (0.012 in.) in the smallest diameter (2-mm) nut up to 76.2 mm (3.000 in.) in the largest diameter (24-mm) nut.
