Tension springs are generally made with closed coils and are looped at the ends.
There are various types of loops available. The most common are:
- English loop
- German loop
- Elongated loop
- Swivel loop
Seeing how widespread they are, Mollificio Modenese provides a catalogue of standard springs with English loop.
To determine precisely a tension spring it is sufficient to know: the wire diameter, the diameter of the spring, and the total length of the spring body and the kind of loop. The number of possible combinations is practically endless, however, so the catalogue is inevitably limited.
If you cannot find your spring, do not hesitate to contact us, we can probably make it!
In addition to medium and large series, Mollificio Modenese is available for sampling or limited series, and if necessary, the individual piece.
Upon request, we can assist the customer in calculating the spring.
Among the materials used to make the compression springs we recommend:
- Steel UNI EN 10270-1 SM/SH/DH (noto anche come C72 – C85 – C98) – data sheet
- Stainless steel UNI EN 10270-3 1.4310/1.4301/1.4401 (AISI 302 – AISI 304 – AISI 316) – data sheet
- Inconel X750 – data sheet
other materials are available upon request.
