Rotary Dampers
FDN-63-R

The flat disc brake for one direction of rotation

Continuous Rotation
Damping torque 8.5 +/- 0.8 Nm

The damping direction of the flat, strong FDN rotary dampers with steel body can be either right or left rotation. They can brake directly in the pivot point. ACE rotary dampers are maintenance-free and ready-to-install.

Technical data

Damping torque 8.5 +/- 0.8 Nm

Damping direction right

Construction size Ø 47 mm to 70 mm

Rotational speed max. 50 rpm

Lifetime 50,000 cycles (1 cycle = 360° left-hand, 360° right-hand). Even after this time, the dampers still produce over approx. 80 % of their original damping moment. The service life may be significantly higher or lower, depending on the application.

Operating temperature range -10 °C to +60 °C

Material Outer body: steel; Output shaft sleeve: nylon with metal freewheel

Mounting in any position

Information to the shaft FDN-47: Ø 6 +0 / -0.03
FDN-57 to FDN-70: Ø 10 +0 / -0.03
Hardness > HRC55, surface smoothness R_Z < 1µm mm

Mounting information

Turn the shaft in the opposite direction to the brake direction to avoid damaging the freewheel mount. No axial or radial forces may be induced via the shaft.

Safety information

Do not use rotary dampers as supports. Provide an external guide or support.

Protection systems for motor-driven cooker hoods

For ergonomic handling, modern cooker hoods can be driven by a motor into an up position and then down again. When driven downwards, an AC load can result in a total loss through current being fed back into the voltage source. One of the tasks of ...
