Four Load Classes, Guaranteed Fit, Fully Interchangeable
More than 400 SuperSprings^® are available in four color-coded load classifications. Uniform lengths and diameters provide full interchangeability between load ratings. Spring diameters are guaranteed to fit in the hole and over the rod diameters listed in the dimensional data. Lengths, diameters, rates, and colors are in accordance with ISO 10243.

Engineered for High Performance and Long Service Life
Each SuperSprings^® has the optimum design, pitch, and metallurgical content for efficient performance. Rectangular wire springs are made from a trapezoidal cross section wire, which changes to a “D” cross section during coiling. This shape results in a lower maximum stress level, substantially contributing to longer spring life.
READY ^® applies several advanced manufacturing processes to enhance the life of SuperSprings^®. These include precision heat treating, shot peening to reduce mechanical stresses, and presetting by compressing to solid for increased set resistance and greatest resistance to fatigue.

Dependable Performance is Quality-Assured
SuperSprings^® are manufactured exclusively from vacuum degassed, valve spring quality alloy steel. State-of-the-art equipment, including CNC coiling and grinding, is employed to achieve consistent dimensional accuracy within narrowest tolerances. Each production run is thoroughly inspected and documented to maintain strict quality. The result is a die spring of unsurpassed quality which many of the world’s most demanding users specify for long, dependable performance

SuperSprings^® Selection and Use
As the ratio of preload to total deflection increases, spring life increases. We recommend that you use a generous preload in your tool design whenever possible.
As the ratio of total deflection to free length decreases, spring life increases. Spring life can often be improved by drilling the spring pockets deeper and selecting the next longer spring.
The chart below and the spring tables presented on the following pages are designed to help you quickly select the die spring best suited to your needs.
