Product Description
Our single leg torsion spring, also called stainless steel torsion spring, is precision manufactured by CNC spring machines for industrial mechanical rotation and reset structures. The core coil and two differently shaped torsion arms are integrally formed in one step. Raw material is premium 304 stainless steel, finished with passivation treatment to resist oxidation and corrosion.
As a reliable spring manufacturer, we provide full OEM and custom service for custom torsion spring. We can produce parts per your drawings or samples, adjusting wire thickness, coil count, outer diameter, torsion arm length, bend angle and torsion torque to fit your equipment’s assembly structure. All products go through tempering stress relief and strict dimensional & torsion testing before delivery.

Custom Services
- Custom production according to customer drawings, physical samples or torsion force requirements
- Adjustable parameters: wire diameter, coil outer diameter, coil quantity, torsion arm length, bend angle and torsion torque
- Multiple material options: 304 stainless steel, carbon spring steel, alloy steel
- Flexible surface treatment solutions: passivation, electroplating, black oxide, ultrasonic cleaning
- Support small trial orders and mass bulk production
Product Advantages
- CNC integrated forming & tight ±0.02mm tolerance: Avoid inconsistent torsion force and assembly mismatch caused by low-precision torsion springs.
- 304 stainless steel + passivation finish: Solve rust, oxidation and conductivity failure issues in humid working environments.
- Stress relief tempering process: Prevent permanent deformation and torque attenuation after long-term repeated rotation.
- Flexible OEM custom service: Modify torsion arm shapes and angles to perfectly fit your unique mechanical structure, no extra redesign cost.
- Full deburring smooth arms: Eliminate scratch risks to plastic, metal housing and hands during assembly.
Quality Control
- Raw material incoming inspection to verify stainless steel composition and mechanical performance
- Real-time dimension monitoring during CNC forming to control coil size and arm length
- Post-tempering torque test to ensure stable torsion performance
- Deburring & surface inspection to remove sharp edges and uneven coating
- Final batch inspection of size, torsion force and anti-corrosion surface effect before packing
FAQ
- Can you produce custom torsion spring based on my drawings or samples?
- Yes. We provide full custom service and OEM production, all torsion arm dimensions, angles and torque can be customized to your demands.
