Custom Torsion Spring with Ø0.2-8mm Wire Diameter and Precision CNC Coiling in Stainless Steel

Custom Torsion Springs are precision-engineered mechanical springs designed to store and release rotational energy by applying torque. Manufactured with advanced CNC spring coiling and forming technology, these springs deliver exceptional torque performance, dimensional accuracy, and long service life for demanding industrial applications.

Our custom torsion springs are available with wire diameters ranging from Ø0.2mm to Ø8.0mm and can be produced in various configurations, including single torsion springs, double torsion springs, helical torsion springs, and custom-shaped torsion springs. Each spring is manufactured according to customer drawings, samples, or technical specifications to ensure optimal performance and seamless integration.

Produced from premium materials including stainless steel (SUS302, SUS304, SUS316), music wire, carbon spring steel, alloy steel, phosphor bronze, and beryllium copper, our torsion springs offer outstanding elasticity, excellent fatigue resistance, high torque output, and superior corrosion resistance. Multiple surface finishing options are available to enhance durability in harsh operating environments.
