High Torque Torsion Spring

Name: China Customized High Torque Torsion Spring Manufacturers Suppliers Factory - Pricelist - Zhongxin
Brand: Zhongxin
SKU: 308400262

High torque torsion spring is a heavy-load torsional elastic component built for large torque working conditions. It adopts thick wire and large outer diameter to output powerful torsion force and meet heavy-duty demands of industrial machinery.
We produce robust high torque torsion spring with wire diameters 1.0mm–8.0mm, outer diameters 10mm–150mm, and customizable torque from 1N·m to 200N·m. Precise coiling and heat treatment guarantee uniform force output within the full rotation angle of each high torque torsion spring.

Product Introduction

Torque Performance

Large torque output

Thick spring steel wire paired with optimized coil quantity delivers strong torsion bearing capacity.

Stable torque output

Accurate thermal processing and winding control maintain consistent torque during repeated rotation.

Reliable structural strength

65Mn, 82B high carbon steel and 60Si2Mn, 55CrSi alloy steel provide high load resistance.

Superior fatigue resistance

Stress optimization and standardized heat treatment extend service life under frequent torsion cycles.

Rotation Direction & Surface Treatment

Clockwise, counterclockwise and bidirectional torsion are all supported. Surface options include natural finish, black oxide, zinc plating, plastic coating and electrophoresis to meet anti-rust and appearance requirements.

Application Fields

Widely applied to industrial doors, heavy machinery, auto parts, agricultural machinery, hardware fixtures and power tools requiring large torsion output.

Professional Design & Calculation Capacity

Baoding Zhongxin Spring Manufacturing Co., Ltd. has an experienced technical team with mature spring design calculation capabilities. For high torque torsion spring with strict design standards, our engineers input torque, rotation angle and installation space data into professional spring design software to calculate optimal wire diameter, outer diameter, coil count and material. The design fully considers stress distribution and fatigue life to ensure stable performance in actual equipment. Professional design support lays a solid foundation for reliable product quality.
