The most popular flexible shaft coupling in Japan that is compliant with JIS B 1452-1991 "Flexible Flanged Shaft Couplings". With a simple structure comprised of a flange and coupling bolts, this bushing is easy to mount.
Bushings can be replaced just by removing coupling bolts. This makes maintenance and service easy.
