Gas Springs Material

Standard Gas springs:

Cylinder tubes from ST.37-BK or NBK to DIN 2391/93/94, coated or yellow chromatised.
Rods from hard chrome Ck45 or 20 MnV6. Guides from bronze RG7 (2.1090) or aluminium 51 ST, or galvanised steel.
Seals from Polyurethan. O-rings from rubber NBR (nitril elastomer) 70 shore A.

There is almost always one Gas spring in dimension and strength suitable for your specific purpose, we are at your disposal in any technical support and will help you during application stage.

Different kinds of fittings are possible (welded or screwed).

Operating conditions

Operating temperatures range from -30°C to +80°C
Working cycles per minute: maximum quantity of 6 full reciprocating strokes. For higher rates please contact us.
Endurance behaviour based on 30.000 working cycles test: 15 % maximum performance loss (actual test results will vary according to stroke length and nominal force value).
Nominal data is given for +20°C reference temperature, For each step of 10°C, force variation is 3.4 %.
For example: F1 nominal force of 500N (at+ 20°C) will become 525N at +35°C and 440N at -16°C.
