Information

Gas springs are designed to relieve and compensate totally or partially the weight of moving parts.
Gas springs are suitable for all purposes and have unlimited application possibilities in Buses, Cars, Lorries, Trailers, Agricultural machinery, Windows, Aeroplanes, Trains, Smoke outlet hoods, Seats, Beds, Photocopy machines, Sky lights, Emergency Exits, turning and lowering of all kinds of equipment.

Whe are also producing Height adjustment units, hand or electrically driven, which are suitable for many purposes, such as Desks, Work places, CAD tables, Machines.

The Gas spring consists of a pressure cylinder (filled with Nitrogen and oil) in which slides a piston-rod sub-assembly.
The self-contained pressured gas generates an axial force on the cylinder-rod system, making the whole device work as a compression spring. The rod speed is always under control with added dampening effect near the end of the rod extension stroke. Fittings on rod side (welded or screwed) or thread ends.

Forces

Forces are measured at 10 mm of the stroke ends (( at 5 mm for strokes < 50 mm). Gas Springs are progressive. The difference between Force F1 at the close end of the extension stroke and F4 at the end of the inward stroke in % is:

The progressiveness of Airax Gas Springs:

6/15 = F1 +27 %
8/20 = F1 + 25%
10/22 = F1 + 33 %
14/28 = F1 + 45 %


The progressiveness of T.Technics Gas- Push- Springs:

4/12 = F1 + 19 %
6/15 = F1 + 27 %
8/19 = F1 + 33 %
10/23 = F1 + 33 %
10/28 = F1 + 21 % 12/25 = F1 + 42 % 14/28 = F1 + 52 % 14/35 = F1 + 28 %
14/40-42 = F1 + 17 % 20/35 = F1 + 80 % 20/40-42 = F1 + 45 % 20/45 = F1 + 33 %
30/60 = F1 + 40 % 30/65 = F1 + 33 % 40/100 = F1 + 25 %  


The progressiveness of T.Technics Gas- Pull- Springs::

6/19 = F1+ 33 %
8/23 = F1 + 36 %
10/28 = F1 + 36 %
14/40-42 F1 + 42 %


Tolerances in Force are:

F1 20N tot 50N +/- 10 Newton F1 50N tot 250N +/- 20 Newton F1 250N tot 750N +/- 30 Newton
F1 750N tot 1500N +/- 50 Newton F1 1500N tot 2500N +/- 100 Newton F1 2500N en meer +/- 250 Newton

Tolerances in Length from Gas Springs +/- 2 mm.
