Green Raymond Die Spring Catalog | Extra Heavy Pressure

Photo of Raymond green die springRaymond green die springs are made by Associated Spring and color coded with blue paint to indicate that the springs have a medium duty pressure rating.

The efficient Operating Range is 15% to 20% of the free length (L). Maximum deflection = 20%. Long life = 17%. 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 20% deflection (F) and spring force in pounds for each medium pressure Raymond Die Spring in the Green Raymond Die Spring Catalog. 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.
