SGF flexible couplings are flexible couplings. They are used to compensate radial, axial or angular displacements of rotating components (e.g. shafts), to dampen vibrations in the drive train and to minimise torque peaks. The SGFlex-3F Series coupling system incorporates industry proven SGFlex couplings with solid steel flanges to provide an integrated solution to our customers. SGFlex couplings are highly durable, reinforced flexible couplings made of high-quality elastomer and strong cord reinforcement for safe and effective torque transfer no matter what the application. they are able to operate in extreme conditions. Some common applications
include Pump systems, Hydraulic drives, Conveyor drivelines, compressors , fans and blowers, augers, agitators, mixing machines, vibrating screens, test benches, CHP and many more.
