Installation recommendation: Oil brake

Take advantage of the expertise and experience of our specialists. Please complete this installation recommendation and attach a drawing/sketch. You will then receive a
non-binding offer. Please select the appropriate installation case and tell us your requirements. Please complete all fields marked with *!
Please note: Due to their function, oil brakes have an undamped free stroke. The damping behavior also changes considerably when the temperature changes.

More about the oil brake

Required information

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.

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.

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.

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.

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

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

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

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

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.

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.

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