Vetus Gas Shock Absorber

Gas cushioning, stainless steel AISI 316, specially designed for marine use. All essential components are made of AISI 316 stainless steel or synthetic materials. Special seals ensure that there is no gas leakage, thus guaranteeing a long life cycle. When positioning vertically, ensure that the piston rod is facing downwards. 
• Fixings included.

There are many applications on board where the assistance of a gas strut will reduce the effort required. For example, heavy deck hatches or locker doors. V-Quipment gas struts are specifically designed for marine use. All external parts are made of stainless steel (AISI 316) or synthetic materials and the special seals guarantee long service life. When fitted vertically, make sure that the piston rod is pointing downward.

These gas-filled cylinders are supplied complete with fixings.
In order to calculate the maximum admissible weight which can be supported, the following data is required:
F = Force of the gas strut in N/m (see table)
G = Weight of the object to be lifted in N
W = Width of the object to be lifted in mm

The calculation goes as follows:
Force in N/m = (G 1x0½00W)/1000

Example:
The weight (G) of a hatch is 11 kg (≈110 N). The width (W) of the
hatch is 600 mm.

This means that:
(110 x 300)/1000 = 33 N/m is needed to hold the hatch open.

In the table we find that GASSP44 delivers 28.8 N/m, which means that an additional 4,3 N/m will have to be applied by the user.
In the case of two gas struts GASSP38, 18,9 x 2 = 37,8 N/m is delivered by the struts. In this case the user will have to push the hatch down with a force of 4,8 N/m.
