Characteristics

• 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.
