The constant force spring stainless steel coil system, through the specific machine of the steel strip of high strength setting, when the external force to straighten, spring will roll back and stretch, however, achieve our goal to return to the starting point we specified in the shift. The advantages of constant force spring than the traditional linear spring: to maintain a certain degree of elasticity are all trips, prestressed short trip, as long as the short stroke can reach the required elastic, the original length is less than the linear spring, unlimited travel.
The constant force spring applications: store shelves and display, LCD screen and fan motor carbon brush, the height adjusting air nail gun and stapler, curtains and windows and doors
