Product Description
FCL Coupling/Shaft Coupling /Pin & Bush Coupling /FCL Flexible Coupling/NBK FCL Coupling is widely used for its compacts designing, easy installation, convenient maintenance, small and light weight.
As long as the relative displacement between shafts is kept within the specified tolerance, couplings will operate the best function and have a longer working life.
Thus it is greatly demanded in medium and minor power transmission systems driven by motors, such as speed reducers, hoists, compressors, conveyors, spinning and weaving machines and ball mills.
