Gas springs are used in many different products - cars, boats, trailers, chairs, hatches, doors, motor heads, agricultural machinery etc. When something needs to be lifted or opened, the gas spring is often the best and most practical appliance available. The potential applications are almost endless: combining a gas spring with your own ideas and innovative thinking can create new and functional products.
A gas spring consists of a piston housing, a piston rod, a piston and a sealing system. It is charged with nitrogen gas at a very high pressure (up to 230 bar) in order to create a counterforce. Nitrogen gas is inert and is not flammable. Nor is it poisonous. Besides nitrogen gas, there is also a small amount of oil in the gas spring. The oil provides the right amount of lubrication at the same time as it provides the gas spring with a hydraulic damping at the end of its stroke.
Gas springs are maintenance free. Never lubricate a piston rod with grease or oil. The piston rod should not be painted, and it should also be protected from blows and other mechanical damage. Any deformation of the cylinder can cause damage that could compromise the sealing system. Gas springs should not be subjected to lateral impact. If light lateral impacts are unavoidable, special fastenings are available that can reduce the effects of such impacts.
Valeryds’ gas springs operate in ambient temperatures from -35°C till +90°C. Gas springs must not be heated, nor placed in an open fire.
Gas springs consist mainly of metal, so they can be recycled. However, they must first be depressurised.
Connections are essential to ensure a controlled output force. This guarantees ideal stroke and force transfer. Valeryd stocks a large selection of fastening eyes, fork connections and angle ball joints.
