The natural type power spring is made directly by the wrapped steel,  while the prestressed force type power spring will finalize the shape first, then reverse the direction into a spiral shape, its shape after spread out just looks like the letter S , hence it is also known as the S shaped spring. When we use the Retractor spring, we need to use a case to confine its outer diameter, the middle of the spring is connected to the line shaft. Once the line shaft and the spring do relative rotation by the external force, the spring will be rolled onto the line shaft and store power. After the external force disappears, the spring generates torque force to drive the line shaft, and output the storage power via the line shaft at the same time. Comparing under the same specification spring, the prestress force type can store more torque force of  25%~40% , it can provide more rotation turns under the same space.   Check the following specification which you can get fast shipping and free sample: 0.4*4*1799mm 0.4*4*2030mm 0.4*4.75*2515mm 0.4*4.75*3164mm 0.45*4*2371mm 0.45*4*2335mm 0.45*4.75*3005mm 0.45*4.75*3034mm 0.45*6*3438mm 0.5*4*1985mm 0.5*4*1962mm 0.5*4.75*3144mm 0.5*5*2405mm 0.5*5*1900mm 0.5*5*2485mm 0.5*6*2304mm 0.5*6*2444mm 0.5*6*2408mm 0.55*4.75*3377mm 0.55*4.75*4766mm 0.55*4.75*2341mm 0.55*4.75*3363mm 0.55*5*2650mm 0.55*7*2380mm 0.6*4.75*2385mm 0.6*4.75*2344mm 0.6*5*2928mm 0.6*5*2627mm 0.6*5*1902mm 0.6*6*2952mm 0.65*6*2519mm 0.8*6*2790mm 0.4*4.8*2900mm 0.6*5*2900mm 0.6*7*3700mm 0.7*4.8*2500mm 0.5*4*2400mm 0.6*4.8*2500mm 0.65*6.25*3000mm 0.6*4.75*2500mm 0.5*4.75*2400mm   Welcome RFQ of  Retractor spring: please send us below details for OEM service: 1) material 2) size ( thickness, length, width,ID,OD) 3) quantity 4) drawings or sample   You are right to choose us: 1.
