What is Torsion Spring?
A torsion spring is an elastic component that stores mechanical energy by twisting around its axis, generating restoring torque proportional to the rotation angle. Main types include helical torsion springs, clock springs, and torsion bars.Stainless Steel Compression SpringsSUS304, single torsion spring with gap, straight arms
