BS standard (European regular) roller chains require unique BS sprockets (RS sprockets/JIS standards can’t be used due to a different tooth width and outer diameter).

Sizes, hardened teeth specifications, and bore finishings not proven in the sprockets dimensional chart are also available on an MTO basis. Contact a Tsubaki representative to find out more.

Fit Bore Series is also available with finished bores.

Sizes not demonstrated in the dimensional chart are also available on an MTO basis (For instance: 20B, 56B). Contact a Tsubaki representative for more information
