Rotary Dampers
FDN-63-R

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.
