Four Load Classes, Guaranteed Fit, Fully Interchangeable
Almost 500 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 SuperSpring® 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 is designed to help you quickly select the die spring best suited to your needs.
Taking a Closer Look:
Most die spring manufacturers will claim that based upon in-house testing, their spring outperforms the competition. To eliminate all bias, we went outside and asked the prestigious Spring Research and Manufacturer’s Association to life test our SuperSpring® against the competition. The results of this independent test, certified under Test Certificate No. 002860, proves the long-life performance of our SuperSpring® :
The springs were cycled between lengths corresponding to the ‘catalog’ maximum deflection conditions of 23.97mm and 18.80mm at a test speed of 3000 cycles/minute. The results have also been analyzed by means of the ‘weibull’ technique, and a value of ‘B10’ (the life in cycles which 90% of springs would be expected to survive without failure) determined for each batch.
The B10 values are:
- READY SuperSprings® 333,139
- RAYMOND springs 152,159
- DANLY DIE SET springs 117,706
We take die springs very seriously … that’s why we recently built the most sophisticated die spring manufacturing plant in the world. You won’t find a better die spring at any price! Not all die springs are the same. Compare SuperSprings® to the competition. You’ll find …
- Longer Life – less downtime means greater productivity.
- Consistent Dimensional Accuracy – tighter tolerances on free lengths and perpendicularity.
- Because our die springs are more dimensionally accurate, our spring rates are more accurate.
- Better Value – With SuperSprings® , you’ll buy fewer die springs and lower your operating costs.
- We offer applications expertise, both technical support from our lab and sales support in the field. We are the die spring experts in our industry.
