Raccomandazione per l'installazione: freno ad olio

Required information

Weight of the flap (kg) ^{* Required field} Explanation for: Weight of the flap (kg)

Total weight 25kg = 2 x 12.5kg

Enter the total weight of the flap here. To determine the weight of an assembled flap, proceed as follows: Hold the flap horizontally and weigh the end facing you with the hinge side facing away from you. The total weight of the flap is twice the measured weight. Note: This method is only suitable for simple rectangular flaps.

Center of mass Explanation for: Center of mass

X (mm)

Y (mm)

The application's center of mass refers to the pivot or hinge point.

For symmetrical flaps, the center of mass is located in the middle of the flap.

CAD programs enable precise calculation of the center of mass.

The more precisely the center of mass is determined, the more accurate the calculation can be.

Starting angle of the flap αM (°) ^{* Required field} Explanation for: Starting angle of the flap αM (°)

Enter the angle in degrees when the flap is closed (starting from the horizontal, see illustration). You can download our paper protractor or measure the closed and open angle with your smartphone or tablet.

Opening angle α (°) ^{* Required field} Explanation for: Opening angle α (°)

Enter the desired opening angle here (from fully closed to fully open).

Download our paper protractor or use your cell phone or tablet to measure the angle when closed and open.

Flap length (mm) ^{* Required field} Explanation for: Flap length (mm)

Indicate the length of the flap. To do this, measure the side on which the pivot point is not located. (see illustration).

Operating temperature Explanation for: Operating temperature

Since the oil reacts very strongly to temperature changes, the operating temperature is necessary for the calculation

Damping direction ^{* Required field} Explanation for: Damping direction

Pressure

Tension

Both sides

Pressure = damped when retracting, damped when extending
Tension = damped when extending, undamped when retracting
Both sides = damped retracting and extending

Opening time ^{* Required field} Explanation for: Opening time

Time that the application should/may take to open/close

Material ^{* Required field} Explanation for: Material

Steel

V2A

V4A

Choose between steel and stainless steel here. The two stainless steel variants V2A and V4A differ primarily in their composition. V2A stainless steel is more sensitive to chlorides and acids, which can lead to (localized) corrosion. Stainless steel V4A, on the other hand, offers greater corrosion and environmental resistance due to its special composition, especially in aggressive environments such as salty areas.

Gas springs made from V4A stainless steel are also characterized by their particularly high quality. They are equipped with a grease chamber that ensures even lubrication of the gas spring seal in every position and have a wiper that wipes dirt off the rod so that it cannot penetrate the gas spring.

Field of application

Number of dampers per flap (pieces) ^{* Required field} Explanation for: Number of dampers per flap (pieces)

Please select the desired number of dampers here. As a rule, we recommend the use of two dampers - one on each side of the flap. Alternatively, it is also possible to use only one damper, although in some cases this can lead to the flap warping or not closing completely at the fixing point. To avoid this, the damper should be fitted in the middle of the flap.

Series production ^{* Required field}

Yes

Please select whether it is a one-off or recurring requirement.
