In places where, due to the failure of gas springs, damage can occur to persons and / or goods, additional safety measures must be taken. Gas pressure or gas tension springs must always be stored with the piston rod pointing downwards. After a prolonged period of rest, an adhesive effect can develop. This means that a higher force may be required to operate the gas spring during initial use.
A minimal amount of hydraulic oil can escape during use. Therefore, be careful with, for example, food and groundwater. For special designs, gas springs can be supplied with a non-toxic oil. To ensure continuous lubrication of the seal, gas springs must always be installed with the piston rod pointing in the downward direction. "Dry running" of the piston rod seal leads to damage and therefore loss of pressure.
The piston rod must never be damaged, soiled or painted. Paint residues or dirt irrevocably lead to damage and to failure of the gas spring. Rigid installation of the gas spring should be avoided. Eyes, forks, etc. must be able to turn freely to avoid transverse forces on the gas spring. Bolted fastening parts must be screwed on completely in a bearing manner. If fastening parts can vibrate loose, they must be secured (glued).
Gas springs may only be loaded axially. Gas springs may be used as an end stop if the load does not exceed the force + 30% stated on the gas spring. Gas springs must never be overstretched or swaged. Standard gas springs can be used at temperatures from -10˚ to + 50˚ Celsius.
Temperature fluctuations influence the strength of the gas spring (approx. 3.4% per 10˚ C). On request we can produce gas springs that can be used at temperatures from -30˚ to + 200˚ Celsius.
Gas springs are not safety parts. Gas springs are subject to wear and must therefore be replaced regularly, depending on the intensity of use. Gas springs contain high gas pressure. Gas springs must therefore never be opened or damaged.
