Stainless Steel U-Shaped Double-Arm Torsion Spring
The U-shaped rectangular bent arms on both ends snap directly into slots or plates, delivering precise and reliable return torque for latch, clamp, and pedal mechanisms.
Precision cold-wound from SUS304 stainless steel wire as a single integral unit, the U-shaped bent arms on both ends are precisely formed using dedicated tooling with standard bend angles and clean flat tips. The U-shape allows the spring to snap-mount into pre-cut slots or plate edges without additional fasteners, greatly simplifying assembly while effectively preventing displacement under load. The tightly wound coil body delivers stable linear torque output, and the stainless steel body provides natural corrosion resistance for high-frequency return applications in consumer goods, industrial equipment, and precision instruments. Two size variants cover different load requirements.
Dual U-shaped rectangular bent arms for snap-fit mounting — no additional fasteners needed for efficient assembly.
U-arm structure prevents spring displacement during operation for stable and reliable performance.
SUS304 stainless steel body with natural corrosion resistance for consumer and industrial applications.
Tightly wound coils for stable linear torque output and excellent fatigue resistance under high-frequency use.
Two size variants in the same series covering different load levels and installation dimensions.
U-arm width, arm length, wire diameter, and torque angle fully customizable per drawings.
Application areas: Door lock latch return mechanisms / Desk lamp clamp spring arms / Electric scooter pedal return / Stationery and document clips / Industrial sensor snap-fit retaining springs
