U.S. Tsubaki Curved chain has additional clearance between the pins and bushings and between the roller links and pin link plates to permit extra flexibility and greater lateral displacement. The basic dimensions of this chain are the same as those of ASME/ANSI standard roller chain.

U.S. Tsubaki's unique design of the curved chain does not taper the pin diameter, which allows the pin diameter to be uniform throughout.
