Information about extension springs

All standard extension springs are designed to withstand a static load, the spring is put under a temporary, constant load in a process. After this process the extension spring returns to its retracted position. Extension springs can be loaded quasi-static (almost constant) or dynamic. The advantage for technical extension springs is that if the spring is properly adjusted, the lifespan should be virtually unlimited.

The standard material of all our technical springs is spring steel are in accordance with DIN 17223 C / 1.1200 / EN10270-1 and stainless-steel material according to DIN 17224 / X10CrNi 18-8 / AISI 302 / 14310 / EN102730-2.

Standard extension springs are wrapped on the right and have two closed German eyes. The working temperature for spring steel is a maximum of 80 degrees Celsius and for stainless steel a maximum of 250 degrees Celsius. Standard technical springs are oiled.
