Gas Springs
We offer gas struts in various lengths, diameters, materials, and forces. While the majority are crafted from steel, we also provide options in stainless steel. When it comes to installing your gas strut, browse our selection of mounting parts and pick the one that best suits your needs for optimal application.

Radial valve
Via the radial valve, the force of the gas spring can be adjusted when it is built in. Radial valves need to be considered when calculating the length of the gas spring (GL).
Wiper ring
The wiper ring prevents foreign matter from entering into the gas springs. Piston rod sealing
Prevents humidity, cleaning agents and other foreign matters from entering into the release system of the locking gas springs
Grease chamber
Permanent lubrication of the piston rod; thus lower friction forces and installation of the gas spring independent from the position. When designing the gas spring, a reduction of the usable stroke needs to be considered.
Valve
The valve allows the force of the gas spring to be adjusted. In the gas spring, it is located at the threaded pin of the base plate; in the tension spring, it is designed as a valve section on the piston rod.
Protection tube
Protects the piston rod from mechanical damage. Reduces the risk of bending for long strokes
Floating piston
Oil-hydraulic damping along the entire stroke, independent of the installation position
Locking device
Mechanical locking for extended piston rod. The locking device needs to be considered when calculating the length of the gas spring (GL).
Short release
The release way for locking gas springs is 0. 1 - 0.2 mm (standard
2 - 5 mm).
B3 - Sealing system
For gas springs with high forces and increased wear, e.g. use in building machines. Allows an installation of the gas spring independent of the position. When designing the gas spring, a reduction of the usable stroke needs to be considered.
NT Low-temperature design
For use of gas springs at an ambient temperature of up to - 40° C. Allows installation of the gas spring independent of the position. When designing the gas spring, a reduction of the usable stroke
needs to be considered.
HT High-temperature design
For use of gas springs at an ambient temperature of up to 200° C. Allows installation of the gas spring independent of the position. When designing the gas spring, a reduction of the usable stroke needs to be considered.
RK Friction element
Increases the friction force for gas springs for the secure positioning
of windows, skylights, etc.
Design and Function
ECKOLD Gas Springs are hydropneumatic, closed and maintenance-free adjustable elements.
The spring force F1 results from the internal pressure (160 bars without load) which is generated by the filling gas, nitrogen. The piston rod is extended when no load is applied, once a load is applied to the piston rod pushing it inwards, the volume in the cylinder is reduced, and the gas is compressed. The gas spring force increases (progression) depending on the diameter of the piston rod and the volume of the cylinder.
Eckold gas springs contain an oil filling for lubrication and end damping. Eckold gas springs are available in steel, in AISI 303/304 and AISI 316L/316Ti.
