Why do gas springs fail?

There are two main reasons for gas spring failure: Firstly, dirt and other particles from the air get inside the spring causing long term damage. The second (and most common) reason for failure of gas springs is the loss of the high pressure nitrogen gas and lubricating oil found inside the spring.

How do gas springs work?

Gas springs consist of a precision rod attached to a piston, moving within a sealed cylinder containing pressurized nitrogen gas and oil. Their force (F) is equal to the pressure differential (P) between internal and external (environment) pressures, acting on the cross-sectional area of the rod (A).

Why is nitrogen used in gas springs?

Nitrogen is used inside gas springs as it is inert and nonflammable; it does not react with any of the internal components.

Is a damper the same as a shock?

The proper name for shock absorbers is “damper” as it serves to dampen motion. While shock is absorbed by the spring, the damper functions to modulate the oscillations (bouncing).

What does N mean in gas struts?

Newton Meters

How do I know which gas shocks to mount?

The force required to hold the lid open (F1) can be calculated using the formula: Gas Spring Force (F1) = Mass of lid x Centre of Gravity / Radius of Force x Number of Springs. The calculations show that the closer towards the hinge the moving mounting point gets, the higher the opening force required.

Where should gas struts be placed?

– The gas strut should always be fitted with the piston pointing down. – Use suitable end fittings and angle joints to avoid coupling jamming. – Gas strut are maintenance free, do not grease or lubricate shaft.

What is a gas spring mount?

Gas Spring: this type of monitor arm is a little more expensive than it’s mechanical counterpart. It silently moves and provides a slower release of force than the mechanical version. Mechanical Spring: the mechanical version is less expensive and last longer than the gas spring.

What strength gas strut do I need?

To calculate the size and the force of the Gas Strut you require for your application use the following guidelines. The extended length of the Gas Strut should be approximately 60% of the door or hatch length – e.g. a 1000mm high door should have a Gas Strut length of approximately 600mm.
