Our factory specializes in manufacturing high-precision double-nut lead screws (double-nut anti-backlash trapezoidal lead screws). They are core components for precision mechanical transmission, fine-tuning feeding and accurate lifting equipment. Adopting a double-nut opposing preload anti-backlash structure, they thoroughly eliminate defects of ordinary single-nut lead screws after long-term operation, such as backlash, loosening, positioning offset and lost motion error.
