specialty stock parts constant force springs constant force spring series smooth operation under stress the lee spring series of extension type constant force spring’s represent the most versatile type available ideal for use when smooth operating forces are required available in four life cycle ranges 2500 4000 13000 and 25000 each spring is made of a high yield type 301 stainless steel strip exerting a nearly constant restraining force to resist uncoiling constant force springs offer the advantage of a smooth operation across the operating range 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 a constant torque is obtained when the outer end of the spring is attached to another spool and caused to wind in either the reverse or same direction as it is originally wound guide to mounting constant force springs if wf t if initial deflection to reach rated load wf max
