Stainless Steel Double Torsion Spring
Featuring a symmetrical double-coil torsion design, this spring delivers balanced torque output for reliable rotary return, support, and linkage control. It is widely used in automotive components, household appliances, industrial equipment, and automation systems.
Manufactured from premium SUS304 stainless steel wire or high-carbon spring steel through precision cold coiling, this double torsion spring features two synchronized coils that distribute load evenly, providing stable torque output and extended fatigue life. The dual-coil configuration maintains balanced force throughout a wide operating angle, reducing uneven loading and improving mechanical stability. Precision manufacturing ensures excellent dimensional consistency, while arm length, angle, winding direction, and installation configuration can be customized to suit various applications. With outstanding corrosion resistance and long-term elastic performance, it is ideal for continuous industrial operation and fully supports OEM production.
