Product Description
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.
The two nuts preload against each other to offset thread clearance, achieving backlash-free transmission, precise positioning and minimal repeat error. Widely applicable to woodworking machinery, CNC equipment, precision machine tools, automated fine-tuning devices, testing instruments, lifting positioning equipment and all types of high-precision transmission machinery, they are the ideal matching parts for working conditions requiring high precision, zero backlash and low vibration.
The full range of double-nut lead screws are precisely forged from high-strength materials including premium 45# carbon steel, 40Cr alloy steel and 20CrMnTi carburizing alloy steel. The materials feature compact and uniform texture, great rigidity, outstanding compression & bending resistance and superior fatigue resistance.
Each product undergoes multiple precision processes: integral quenching & tempering stress-relief heat treatment, carburizing quenching hardening, precision finishing turning, high-precision grinding of trapezoidal threads, high-accuracy straightening and matched lapping & calibration. These procedures completely eliminate internal material stress and prevent bending deformation, thread wear and precision degradation during long-term reciprocating operation.
Designed with exclusive precision trapezoidal thread profiles featuring full and regular tooth shapes with high fitting accuracy, paired with our factory’s precisely matched double nuts, the screws deliver even preload and stable backlash elimination. They operate without lost motion, jamming or axial play, enabling accurate low-speed fine adjustment and stable high-speed transmission, which effectively improves equipment machining accuracy and finished product yield.
Our complete product lineup covers standard double-nut lead screws, extended-length double-nut lead screws, left-right hand double-nut lead screws, high-precision anti-backlash double-nut lead screws, heavy-load double-nut lifting lead screws and more. Combining zero-backlash high-precision transmission with heavy load bearing capacity, they fit rigorous working scenarios such as precision fine-tuning, high-frequency reciprocation, heavy-duty lifting and 24-hour continuous high-precision operation. Wear-resistant and robust, they have long service life and rarely develop backlash after prolonged use.
As an original physical manufacturer, we offer customized processing based on customer drawings and samples for non-standard parameters: custom diameter, thread pitch, lead, overall length, double-nut structure, preload force, left-right hand threads and special mounting holes.
Multi-process quality inspection is implemented throughout production. Matching assembly and full precision testing are carried out before delivery. Standard specifications are well-stocked with stable lead times. We accept bulk orders, supporting orders for precision machinery and urgent overseas export orders.
