All gas springs contain a small amount of oil to lubricate the main seal and rod and provide end of stroke damping (see damping). If standard gas springs are operated and mounted in a rod up orientation, fluid cannot reach the main seal or rod which leads to excessive seal wear and reduced life...

Once a gas spring has left the IGS factory, the only way to adjust its force is by removing some of the nitrogen gas contained inside the tube. Therefore the only possible adjustment will always lead to a less powerful gas spring. On first orders and prototypes, we always recommend that you...

Damping is achieved regulating the flow of gas and/or fluid through the valved orificing of the gas damper piston. Commonly used compression gas springs when mounted in a rod down orientation achieve maximum damping when the piston reaches the oil near the point of full extension. This is shown...

Gas Spring force is normally designated as P1 which is the force measured .2" (5 mm) from full extension in the extending direction. Force is a function of the charge pressure in the cylinder acting on the cross section of the rod. The smaller the diameter of the rod the lower the force at the same...

Gas springs are high friction devices. Users will notice a spike in the force required to first compress a gas spring compared to the rated P1 force of the spring. If tested on a common weight scale, this leads some users to conclude the spring is set at an incorrect force. Sometimes referred...

All IGS springs, with the exception of the micro gas springs, are available with release valves (RV). RV gas springs are fitted with an internal aerospace quality valve located under the removable stud on the cylinder end of the spring. These springs are generally supplied at a higher force than...

A gas filled spring consists of a precision rod attached to a piston moving within a sealed cylinder containing nitrogen at high pressure. Output forces are the result of the differential between the pressure in the cylinder and atmospheric pressure outside the cylinder acting on the cross-section...

The following chart gives the operating and survival temperature ranges for gas springs manufactured with standard, low temperature and high temperature seals. RV refers to "release valve" which is a standard option on most units. The seal properties of the RV reduce the temperature ratings...

The IGS Side Release Valve can be found on the Euroline range of gas springs. It can also be found on custom made gas springs where a SRV was specified. The advantage of this type of release is that the force can be released after the gas spring has been fitted on the application. It makes...

Use standard gas springs rod down, i.e. the spring should be mounted so that it spends most time in a rod down position, within 60° of vertical, thus ensuring the seal stays lubricated. For tension springs the exact opposite is true, i.e. use rod up. Once installed, test at least every three months...
