Special Springs 4 use recommendations The correct use of Special Springs’ die springs assure performance levels well above the lifetime values indicated. Before using the springs, carefully read all the recommendations. Incorrect use can significantly reduce the expected lifetime and may cause damages or injury. Do not exceed the maximum deflection as indicated in the tabs (column D) as it may cause sudden failure of the springs and damages on the tool. Do not store springs in compressed state for long time as it may cause abnormal fatigue to the springs. When using different type of springs in parallel simultaneously ensure that overall deflection and force guarantee a balanced load. When setting the springs ensure the best perpendicularity to the working surface to avoid early failure of the springs. The bigger the guide the longer the lifetime. It is essential to guide all springs with a free length /diameter ratio exceeding 3.5. Avoid to using springs in vertical group not fully guided or using springs inserted in each other as it may cause serious damage or injury. Best working temperature – 30°C + 120°C. Over 120°C and up to 250°C should be considered an average loss of 1% on springs rate for every 40°C. Max Deflection 120 -30 °C 248 2 °F EN EN EN EN EN EN
