Torsion Bar Spring is a type of helical metal spring that stores mechanical energy when twisted. It is made of carbon steel, steel, stainless steel and some other more materials. Bar diameter is 0.30mm and above, finishing is done by nickel plating, chrome plating etc. The load type of this spring is used for torsion and weight of these springs ranges around 3-10kg. Torsion Bar Springs have dimensional accuracy, high sturdiness, corrosion resistant and high durability.
