STABILUS - A company with an innovative tradition Pioneering achievements STABILUS has over 70 years experience in the manufacture of hydropneumatic equipment. In addition to having produced hydraulic dampers over several decades, STABILUS presented the world’s first standard production gas spring in 1962. To date, it has produced over 2 billion gas springs. With its two product lines - gas springs and hydraulic vibration dampers - STABILUS is the world market leader with an annual production of some 140 million units. Worldwide operations With a global distribution and service network and...

Product characteristics, advantages, uses Operating principle of a gas spring The gas spring is a hydropneumatic adjusting element, consisting of a pressure tube, a piston rod with piston and appropriate connection fittings. It is filled with compressed nitrogen, which acts with equal pressure on differently dimensioned cross-sectional areas of the piston. This produces a force in the extension direction. This extension force can be exactly defined within physical limits through the appropriate selection of the filling pressure. Spring characteristic curve and F1 force The spring...

Dimensions according to choice STABILUS offers an extremely wide range of gas spring types, which vary in respect of their external dimensions, speed curves and extension variants, and invariably meet the most stringent requirements. A large selection is included in the STABILUS standard product range and can be delivered at short notice. Service life and maintenance Gas springs are maintenance-free! They are designed to specific requirements and operate for years and years without failure when properly installed. Also for particularly high numbers of load alterations special sealing...

Lifting, lowering, moving and adjusting With their accurately adjusted extension force and application-specific damping LIFT-O-MAT® gas springs offer optimum weight compensation, force support, they open and close flaps and bonnets and ensure user-friendly movement sequences thanks to their damping characteristic. Characteristics and benefits .. Numerous size and force variants available as standard .. Linear spring curve for uniform force progression over the entire spring travel .. Available with progressive or degressive spring curve for force support at stroke start or end position .....

Variable positioning, rigid or spring blocking BLOC-O-LIFT® gas springs raise loads with an accurately tuned extension force and application-specific dampening while ensuring user-friendly movement sequences. In addition, BLOC-O-LIFT® gas springs can be blocked in any position, with springing or rigid blocking in the extension or compression direction depending on the design. Variable blocking is made possible by the valve integrated into the piston which separates both pressure chambers gastight. When the valve is closed, thereby interrupting the gas exchange between both pressure...

Hydraulic dampening of vibrations and motions Dampers are needed to positively influence the nature of movements and vibrations. They are designed to match the particular application. Oil-hydraulic dampers consist of a pressure tube, a piston rod with piston system and a piston rod connection fitting. The movement of the piston presses the filling medium (oil) through suitably dimensioned bores into the piston, thus producing the desired damping force. For stepless height adjustment of seats STAB-O-MAT® and STAB-O-BLOC® gas springs are blocking gas springs specially designed for the...
