NBK’s FCL-BUSH flanged shaft coupling

The most popular flexible shaft coupling in Japan that is compliant with JIS B 1452-1991 “Flexible Flanged Shaft Couplings”.
Simple structure comprised of a flange and coupling bolts. Easy-to-mount.
Bushings can be replaced just by removing coupling bolts. This makes maintenance and service easy.
While it absorbs misalignment such as eccentricity and argument, it prevents noise by absorbing torsional vibration. It will not transmit thrust load, either.
Two types are available: Cast Iron FCL and Carbon Steel FCLS.
