mechanicalsteel

Rotary Dampers FDN-L The flat disc brake for one direction of rotation Continuous Rotation 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. Damping direction left 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 RZ < 1µm
