Stainless Steel Torsion Spring

Solution

A Stainless Steel Torsion Spring is a mechanical component designed to store and release rotational energy through twisting motion. Made from high-quality stainless steel, it offers excellent corrosion resistance, durability, and load-bearing capacity. These springs are widely used in automotive, aerospace, medical devices, and industrial machinery due to their ability to withstand repetitive stress and harsh environments. Customizable in wire diameter, coil count, and leg configuration, they provide precise torque for applications like hinges, clamps, and switches. Their non-magnetic and hygienic properties make them ideal for specialized industries.
