Select 20 x 102mm 3/4 x 4in Green Light Duty ISO Die Spring

Always use as many springs as the die will accommodate; doing so will produce the required load with the least amount of deflection. It will also increase the useful life of the spring; reducing the chances of spring failure and the resulting downtime; and reduce production loss and increased maintenance cost. The more rapidly a spring works, the more attention must be paid to its fatigue limits. Optimum performance can be achieved by pre-loading the spring and deflecting the spring the minimum amount possible. Operating at or near the maximum deflection will reduce the cycles below the optimum level and should only be used for short run, slow cycle applications. Select springs in the appropriate duty rate that will operate efficiently at the required travel. Calculate the number of springs needed by dividing the load supplied by one spring into the total load required. Always round the total number of springs require to the next higher even number for balanced performance.
