*Psi and Bar relates to the pressure inside the gas spring cylinder for this series.

*Kg and Lbs relates to the weight balanced by a specific Newton for this series

*Force For each application add 10% force to compensate for friction etc.

FORCE CALCULATION FOR HATCHES AS FOLLOWS:

Using 1 gas spring 8-18-250 with 500 Newton Force:

A hatch of max 39.5 inch or 1000 mm length with a weight of max 55 Lbs. or 25 kg

Using 2 gas springs with 500 Newton Force a hatch can weigh max. 110 lbs. or 50 kg.

Max Hatch Length: Best be max. 39.5 inches or 1000 mm.

Length is the distance from the hinge pin to the locking side.

Install the gas spring as far away as possible from the hinge within the range of the stroke.

Alternative: For a smooth operation we advise using the next series up – a 10-23-250 with 500 Newton.

Please note: Torque on the hinges will be at least be twice the force of the weight of the hatch.

GENERAL INFORMATION:

Use incremental lesser force for gas springs when hatch is lighter.

Use gas spring with a shorter stroke for smaller hatches.

When the hatch is thick, use a gas spring with the next size up. (For instance: 10-23-series with 300 mm stroke)

Use our 10-23 series gas springs with a Newton Forces up to 1200 N

Use our 14-28 series gas springs with a Newton Forces up to 2500 N.

Concidder our charging Kit #63.110 for professional users to charge your own gas spring.

Considder our Bleeding Kit #63.001 to bleed down the pressure in your gas spring.

Use mathematical calculations and scaled drawings to identify gas springs size and series
