Constant tension spring stainless steel spring

Constant force spring is made by winding the steel strip into a coil which exerts a nearly constant retraining force to resist uncoiling. By comparing the differences between constant force spring and traditional wire springs, the advantages will be obtain as following: To exert nearly constant force during entire extension. Short initial deflection, it means that reaching the rated load at short extension. Long extension capability. 

Constant Torque Spring can be applied to retrieving, counterbalancing, drive motor, self-retractor, cordless shade, self-sufficient radio.

Ningbo Yunsheng Flat springs are made of flat strip steel and are used in many applications and are ideally suited for applications where space is limited or where the spring can be used as part of mounting assembly.
