MaxLife Red Stripe Die Springs | Medium Heavy Pressure

Photo of MaxLife red die spring MaxLife red stripe die springs are made by Dayton Lamina and color coded white with a red stripe to indicate that the springs have a medium heavy pressure rating.

The efficient Operating Range is 20% to 37% of the free length (L). Maximum deflection = 37%. Long life = 25%. Optimum life = 20%. Travel to solid is for reference only and not intended for operation. Deflection beyond the efficient Operating Range could create a safety hazard or and result in premature spring failure.

drawing of spring deflection parameters

The chart below provides the 37% deflection (F) and spring force in pounds for each medium heavy pressure MaxLife Die Spring. Also shown is the travel to solid deflection (S) and the spring force constant (K) for each spring.

Use the following equation to calculate the spring force in pounds for a given spring and deflection; Force = K x 10 x F, where K is the force constant and F is the deflection in inches.
