Stainless Steel Torsion Spring
We produce functional stainless steel torsion spring with wire diameters from 0.3mm to 5.0mm and outer diameters from 5mm to 80mm. Clockwise, counterclockwise and bidirectional torsion designs are all available. Precise heat treatment stabilizes torque output and improves the fatigue resistance of every stainless steel torsion spring.
Rebound Performance
Stable rebound force
Fixed elastic modulus of stainless steel plus accurate heat treatment delivers uniform torque output within the full working angle range.
Superior anti-fatigue property
Optimized structural design and thermal processing prevent failure after repeated torsion cycles.
Uniform stress distribution
Large smooth arc transitions at torsion arms reduce stress concentration and extend overall service life.
Wide torsion angle range
Custom structural design allows large rotation angles to meet different mechanical stroke demands.
Product Characteristics
• Rust & corrosion resistant: SUS304 or SUS316 stainless steel maintains stable performance under long-term humid or mildly corrosive conditions.
• Refined surface finishing: Natural finish, electrolytic polishing and passivation improve surface appearance and anti-corrosion capacity.
• Custom torsion arms: Adjust arm length, bending angle and end shapes freely to match diverse installation and force-bearing modes.
• Controllable precision: Torque and rotation angles can be precisely engineered to meet functional specifications.
Application Fields
Suitable for hardware fixtures, electrical switches, door & window fittings, food machinery, medical devices and chemical equipment needing torsional reset and rust protection.
