Product Description
Constant force spring is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring, but at a nearly constant (zero) rate.
The full rated load of the spring is reached after being deflected to a length equal to 1.25 times its diameter. Thereafter, it maintains a relatively constant force regardless of extension length. The load is basically determined by the thickness and width of the material and the diameter of the coil.
Applications
The constant force spring is an excellent device for applications where a constant load is required. Some of the many applications of constant force springs are in counterbalances, fan lifting , fire damper curtain ,shelf pusher divider ,monitor lifting ,cable grounding ,nail pusher ,slide door ,tilt windows , door closers etc .
