General description

A gas spring consists of a cylinder tube with a piston rod moving reciprocally in it, e.g. piston. The gas spring is filled with nitrogen under high pressure. At the front (rod side) the cylinder tube is sealed by means of a guide through which the piston rod moves back and forth. At the rear (house side) the cylinder tube is sealed by means of a bottom piece.

The pressure is the same on both sides of the piston, since there is a throughflow channel in the piston which, by means of a (small) quantity of oil, also ensures an end damping of both the input and the outgoing stroke. The filling pressure multiplied by the surface of the piston rod determines the extension force of the gas spring.

Equipment:

The Airax gas springs are supplied as standard with a black coated or sprayed cylinder pipe, which gives excellent corrosion resistance.

Our own T.Technics gas springs are produced from / with / from the following materials:

Standard gas springs:

Cylinder tubes from St.37-2 BK or NBK according to DIN 2391/93/94, coated or yellow bichromatised.
Piston rods made of hard chrome-plated shaft CK45 or 20 MnV6.
Guides and base pieces made from material no. 2.1090 (Rg7) or aluminum 51ST, or galvanized steel.
Piston rod seals made of thermoplastic polyurethane or rubber.
O-rings from NBR (Nitrile elastomer) hardness 70 Shore A

Stainless steel gas springs:

Cylinder tubes from the austenitic material No. 1.4435 (316L) or 1.4571 (316Ti).
Piston rods made of hard chromium-plated shaft, workpiece No. 1.4057 (AISI 431) or AISI 316.
Guides and base pieces from material no. 2.1090 (Rg 7).
Piston rod seals made of thermoplastic polyurethane.
O-rings from NBR (Nitrile elastomer) hardness 70 Shore A

Usage:

The gas springs are designed for use with / with / in:
A temperature range of – 30 to + 80 degrees Celsius.
The extension force F1 is measured at + 20 degrees Celsius. A deviation of + / – 3.4% pressure increase / decrease applies per 10 degrees Celsius.

For tolerances on extension and length measurements, see our information calculcations pages.
