Gas cylinders are hydropneumatic adjustment elements. They consist of a tube and a piston rod with internal piston assembly. Fittings on the tube and piston rod make a connection to your application possible.

The heart of the SUSPA gas cylinder is the special sealing- and guiding system, which ensures a hermetic sealing of the inner chamber with low friction, even under extreme environmental conditions.

The gas cylinder is filled under high pressure with nitrogen. A filling pressure results, which in turn acts upon the cross-sectional area of the piston rod. The extension force is generated in this way. When the extension force of the gas cylinder is greater than the force of the counterweight, the piston rod extends; in the case of less extension force, the piston rod retracts. The cross section of flow in the damping system determines how fast extension occurs.

Aside from nitrogen, a defined amount of oil for lubrication and damping in the final position is also present in the inner chamber.

The damping performance of a gas cylinder can be adjusted according to need and task by way of a linear, progressive or regressive spring characteristic.

Reliability as the Highest Measure of Quality

The demands for quality are increasing in the automobile industry as in other industrial branches. Certifications in accordance with QS-9000 and DIN EN ISO 9001 therefore have long gone without saying at SUSPA.

An effective quality management team from purchasing, to manufacturing, to distribution, all the way to the final application, ensure the worldwide good reputation and the reliability of SUSPA gas cylinders.

Our new "space-mat®" principle with components designed in aerospace engineering makes sure that oil is always available at the proper point for the necessary lubrication. In addition, a reservoir out of extremely resilient, largely non-wearing material is filled at every stroke.

This principle makes the installation of the gas cylinder in any position desired possible. We test our gas cylinders 100% according to our internal testing specifications. SUSPA gas cylinders thus have a life expectancy of over 50,000 cycles in completely maintenance-free function. This corresponds on the average to 10 years of use in the automobile branch in the operation of luggage compartment lids and tailgates, or 20 years of use in a skylight.
