BS standard (European regular) roller chains require unique BS sprockets (RS sprockets/JIS standards cannot be used because of a different tooth width and outer diameter).
Sizes, chain sprocket hardened teeth specs, and bore finishings not shown in the dimensional chart are also on an MTO basis. Get in touch with a Tsubaki representative to learn more.
Fit Bore Series is also available with finished bores.
Sizes not proven in the dimensional chart are also on an MTO basis (For instance: 20B, 56B). Get in touch with a Tsubaki representative for more information
