By combining the principle of SKF oil injection method on flexible shaft couplings, a high torque interference fit for plain, cylindrical shafts is obtained. Since there is no need for machining any keyways, splines or tapered shafts, smaller shaft diameters can be used, thus less weight. Categories . Federal Flexible Couplings™ reduce noise; absorb vibration; prevent electrolysis; Important facts about Federal Flexible Couplings™ protects transmission thrust bearings and seals from stress and wear due to shaft misalignment. Bobbin coupling - this is a double flanged coupling, used to space out the propeller shaft, or which can be used with two R&D flexible couplings to double insulated noise and vibration. $13.99 $ 13.
