Product Description

Product Description
Torsion springs, whose ends are rotated in angular deflection, offer resistance to externally applied torque. The wire itself is subjected to bending stresses rather than torsional stresses. Springs of this type are usually close wound, reduce in coil diameter, and increase in body length as they are deflected. Special types of torsion springs include double torsion springs, heavy duty torsion springs, and springs having a space between the coils to minimize friction. Double torsion springs consist of one right-hand and one left-hand coil section and working in parallel
