MaxLife Gold Stripe Die Springs | Heavy Pressure
MaxLife gold stripe die springs are made by Dayton Lamina and color coded white with a gold (yellow) stripe to indicate that the springs have a heavy pressure rating.
The efficient Operating Range is 15% to 30% of the free length (L). Maximum deflection = 30%. Long life = 20%. Optimum life = 15%. 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.
The chart below provides the 30% deflection (F) and spring force in pounds for each 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.
