Red Raymond Die Spring Catalog | Medium Heavy Pressure

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

The efficient Operating Range is 20% to 30% of the free length (L). Maximum deflection = 30%. 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.

The chart below provides the 30% deflection (F) and spring force in pounds for each medium heavy pressure Raymond Die Spring in the Red 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.
