Products

U.S. Tsubaki Power Transmission, LLC. produces high-quality products for a wide range of industries and applications including roller chains, conveyor chains, sprockets, cable & hose carrier systems, clutches and backstops, and continuous flex cables.

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.
