Tsubaki: ANSI Single Pitch Curved (CU) Chain

ANSI Single Pitch CU

ANSI Single Pitch Curved (CU) Chain

Due to Tsubaki's exclusive pin and bush structure and the wide plate to plate clearance, this roller chain has a large side flex radius. The basic dimensions of this chain are the same as ANSI standard roller chain. The ability to use ANSI standard sprockets makes curved transmission simple. Guides are required at all curved areas.
