Rotary Dampers FFD-SW-R Precise braking without oil Continuous Rotation In comparison to other rotary dampers, the ACE FFD product family does not need any fluid to generate the damping torque, but rather works on the principle of friction. That means temperature or speed changes have virtually no influence on the damping torque. The FFD is available in two different body variants and two types of bearings. ACE rotary dampers are maintenance-free and ready-to-install. Damping direction right Construction size Ø 25 mm to 30 mm Rotational speed max. 30 rpm Lifetime 30,000 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: plastic Mounting in any position Information to the shaft Ø +0 / -0.03 Hardness > HRC55, surface smoothness RZ < 1µm
