Conical Compression Springs

Technical drawing - Conical compression springs

This series of conical springs is ideal when stability and a short compressed length are important. The conical shape provides excellent stability at one end, along with greater travel than with conventional compression springs. We have around 100 different sizes of conical compression springs in stock, ready for dispatch. We only have conical springs in stainless steel.

We recommend that you use a maximum of 75% of Sn.

Material

Stainless steel:
DIN 17224 WERKSTOFF NO. 1.4310 EN Norm 10270-3
Working temperature -200 ºC and +250 ºC

Winding direction

Usually to the right

Misc.

This series of conical compression springs is designed to provide travel all the way down to a height (Ln) of 2 x wire thickness. The spring constant is linear due to the variable pitch.

The ends have been finished without grinding.

If the springs are compressed to Ln, the spring will set itself. It will then not return to its original length, L0.

All compression springs set more or less in proportion to travel.

We recommend that you use a maximum of 75% of Sn.

Always dimension a spring so that it delivers the desired travel and force with as little exertion as possible. This prolongs the service life of the spring. Applying maximum load to the spring will shorten its service life and cause it to become permanently distorted.
