Gas springs - Threads 316 - FDA Approved

Technical drawing - GFRF gas springs
Gas springs and gas dampers are made from acid-proof 316 stainless steel. This version can therefore be used in both dry and humid environments. The oil is FDA-approved, so these gas springs can be used in the food industry. The size of the thread depends on the piston rod.

Material

Cylinder and piston rod: Stainless steel gas springs are made from AISI 316 stainless steel.

Oil: FDA-approved oil. The oil is approved for food use. (Omnilube FGH 1046)

Gas: The gas is nitrogen gas.

Stock number

Gas springs in the Sodemann Industrifjedre A/S range are defined based on the thickness of the piston rod, the stroke and the force in N.
Naming of gas spring

Force curve

The force in a compression gas spring increases the more it is compressed, in other words as the piston rod is pushed into the cylinder. This is because the gas in the cylinder is compressed more and more due to displacement changes inside the cylinder, thereby increasing the pressure that results in the axial force that pushes the piston rod.

Description

Gas springs contain nitrogen gas under high pressure. This is a type of gas that cannot burn or explode, nor is it toxic if inhaled. No attempt must be made, in any circumstances, to take the gas spring apart or to refill it - this is extremely risky due to the high pressure! Do not burn, puncture, squash or dent the gas spring, and do not weld the surface of the cylinder. Do not scratch, paint or bend the piston.
