Damping torque 97.36 +/- 8.85 in-lbs Damping direction left Construction size Ø 1.85 in to 2.76 in 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 14 °F to 140 °F Material Outer body: Steel; Output shaft sleeve: nylon with metal freewheel Mounting In any position Information to the shaft FDN-47: Ø 0.24 +0 / -0.001 | Mounting informationTurn 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 informationDo not use rotary dampers as supports. Provide an external guide or support.
