Proven and Reliable
Gas springs are a proven and reliable method of counterbalancing large covers and objects. They offer ideal capabilities for safely lifting, lowering and positioning heavy or cumbersome objects. More versatile than mechanical springs, gas springs offer your product the advantages of speed-controlled dampening, cushioned end motion, simple mounting, compact size, flat force curve, and a wide range of available forces.
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.

An element with many possibilities
Design and function – where else are these criteria as closely linked as in furniture? Apart from fashionable designs, customers are looking more and more for functionality and value in furniture. At the same time, this should not raise the price, though.
This is where the furniture gas springs from STABILUS provide the best opportunities. They open flaps and lids without effort, hold them securely in place, and make sure that they close softly and quietly. They are very easy to mount, maintenance-free, they look good – and they are reasonably priced.

Gas springs and dampers for seat adjustment
With their defined movements, a high level of functional comfort,
a long, maintenance-free life and highest quality, STABILUS
products make office chair seat adjustment more ergonomic.
For example seat height...
With the use of gas springs, the seat height can be
brought into the ergonomically correct position for any
body height at any workstation. A seat with end position
cushioning offers even more seating comfort.
For example backrest...
Continuous contact between back and backrest provides
lumbar support and strain relief for intervertebral discs.
For example seat tilt...
Ergonomically correct seat tilt places different amounts of
pressure on the pelvic bones and the spine, which meets the
ergonomic demands of dynamic seating.
For example synchronous adjustment…
Where seat tilt and backrest can be adjusted to fit the
body, gas springs provide the individual counter-pressure.

Operating principle
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 chambers, the BLOC-O-LIFT® gas spring is blocked. The valve closes automatically when the valve tappet is released externally. The resilient blocking variant is ideal for the smooth dampening of e.g. shocks, impacts or pulse-type peak loads (e.g. in seats and office swivel chairs).

Stainless steel gas springs for the most exacting applications
A compact design, a high level of functional comfort, and high operational safety, combined with the special material properties of stainless steel open up many new opportunities:
For example, in ship building...
STABILUS gas spring facilitate opening and safe propping of flaps and covers, even in a salt-water environment.
For example, in environmental technology…
They easily and safely open and close maintenance flaps and manholes, without polluting the water.
For example, in medical technology…
STABILUS gas springs made of stainless steel can be used in medical devices, hospital beds, and operating tables, especially when non-magnetic properties are required in addition to total cleanliness.
For example, in the food and pharmaceutical industry…
When the gas spring has to be robust against external environmental effects, stainless steel gas springs from STABILUS do convince for many years by their full function and attractive appearance.

Functions:
AdjustHold gas springs are hydropneumatic devices help us to lift, lower, adjust, move, counterbalance the weights easily or without any effort.
It consists of chrome or nitrocarburized steel piston rod, oil and pressurized (max.) nitrogen gas sealed in the steel cylinder and a gas release valve at the end ofthe cylinder to adjust the required pressure for a specific application.
Internal gas pressure increases as piston rod moves into the cylinder (compression). This internal pressure has an actuating effect on the cross sectional area of the piston rod.
This pressure on the sectional area of the piston rod forces the piston rod to move out of the cylinder (extension).
Piston rod extension dampens on a specified point according to the quantity of oil filled in. On the other hand oil lubricates the piston and sealing set to work smoothly for many years
Advantages:
- Pressure adjustment by releasing the gas through the release valve at the end of the cylinder.
- Easy and smooth lifting, lowering, moving, adjusting.
- Hydraulic or dynamic damping in the end of its movement.
- Wide application possibilites due to wide range of end fittings.
- Maintenance free. No need for greasing or lubrication.
Applications:
AdjustHold gas springs are used for sampling. |

Unlike shock absorbers, in this case the viscous frictions are very small. Only the surface frictions remain the same.
The principle is the same as for the piston-type shock absorber, the only difference being the plunger/reservoir clearance which, being larger, ensures the dominance of the compressibility characteristic of the elastomer over its viscosity. |

Gas springs.
Three fixing's types :
- standard with eye welded,
- with rod end bearing,
- with threaded tip.
Compared with the traditional gas springs, its principal advantages are :
- a very low coefficient of stiffness,
- a race being able to reach to 500 mm,
- different forces for the same obstruction,
- a speed controlled extension.
We also propose inflation with the desired pressure of your gas springs.
Temperatures of use : of - 25° with +60°C.
On request, version stainless and different temperature rang.

DICTATOR high-performance push-type gas springs with additional locking
raise objects, hold them in any position desired, and then release them again.
The locking push-type gas springs are available in two types of locking. With cushioned locking the piston rod gives a little in the locked position so the object can recoil. These are easier to manufacture technically and are
therefore the cheaper variety. If the object needs to remain in a fixed
position e.g. hospital beds that tilt, then gas springs with rigid locking must be used.
The locking is released by a pin atthe front of the piston rod.
Dictator furnishes different releasing devices.
Other than the hospital bed shown in the
Locking push-type gas springs are used e.g. in aeroplane seats, drawing boards, hospital beds etc.
DICTATOR locking push-type gas springs can also be supplied with numerous additional´options such as a valve, biological oil, protective tube and oil chamber. |

DICTATOR Pull-type gas springs are the answer to your problems if you
are unable to use normal push-type gas springs due to a lack of space. They work in the opposite way to push-type gas springs as the gas pressure inside the cylinder causes the piston rod to retract inwards.
Depending on how they are installed, pull-type gas springs either open or close flaps, windows and hatchways.
In the same way as with push-type gas springs, we manufacture your pull-type gas springs
- according to your individual application requirements
- also as a single unit, in small or large batches.
We offer a design service, that means, you send us the information on your application and we calculate the required gasspring.
