General Information
The new generation of gas springs is designed to enhance performance in terms of safety and durability. The use of low pressures allows achieving the same initial forces as traditional gas springs while maintaining identical dimensions (diameter and height). Operating at low initial pressures, generally between 100 and 105 bar, offers several advantages:
- It increases the system’s intrinsic safety.
- It reduces the heat generated by friction.
- It extends the service life of the seals and, consequently, of the gas spring.
- It allows for higher operating speed.
- It allows the spring to be used in a range where the gas compressibility ratio is below one at ambient temperature.
- It reduces the pressure rise gradient during compression.
- It reduces the costs associated with using gas springs.
The special design prevents fluids from entering the compression chamber, avoiding overpressure issues typical of conventional gas springs. To protect end users, Xela employs safety systems that activate in three specific cases: when the stroke exceeds the design value (OVERSTROKE), in the event of excessive gas pressure (OVERPRESSURE), and in the presence of uncontrolled return of the moving element. For each of these potentially harmful and dangerous situations, Xela provides at least two safety systems operating in tandem, ensuring maximum reliability.

Pressure
It is the main parameter in gas springs. Compared to other gas springs on the market, Xela’s special design allows it to operate with lower initial pressures. The supply loading pressures for most Xela models is 100-105 bar.
Force
Xela’s new design allows the same initial forces as other gas springs while starting from lower loading pressures. This provides the possibility, when necessary and with appropriate measures, to increase the initial pressure (and thus the initial force) by up to 50% while keeping the radial dimensions under control.
Durability
Gas spring durability is affected by many factors: initial loading pressure, speed (SPM), stroke used, ambient working temperature, correctness of installation and fixing, presence or absence of seal- aggressive contaminants etc. Under normal conditions (initial p of 100 bar, ambient T 20°C, 100 SPM, 90% maximum stroke), Xela far exceeds the values claimed by competitors. Tests, which are still being finalized, have seen Xela reach and exceed even 4 million cycles while still guaranteeing 95% of the initial load. These results, if confirmed in the coming months, would make Xela the product with the lowest cost of use on the world market. Shown is an initial estimate of the cost per million cycles derived from comparative tests performed in the laboratory (40 mm stroke at 120 SPM) on gas springs from the world’s leading manufacturers.
This product is continuously evolving, as Xela — being a revolutionary idea — receives frequent updates.
The rigorous tests we subject our gas springs to provide us with increasingly accurate data. That’s why the information is currently being verified: before using it, please consult with us to develop any specific requirements.
