The helical springs from norelem are machined to the highest precision - the result is, amongst other things, excellent spring characteristics. The basic high quality component is a rectangular coiled wire made of chrome-silicon steel that reacts to pressure. Flat spring ends, ground to a right-angle ensure uniform force transfer and improved seating. The special spring profile enables high alternating and permanent forces and permits use at operating temperatures up to 230 °C. The springs have been heat-treated, abrasive blasted and pre-stressed at block height during production to significantly extend the life expectancy. |
