The Complete Guide to Chain

1.1.2 BS/DIN Roller Chain

Transmission: General usage

Application Example

BS/DIN power transmission chains are regulated by international standards (ISO 606B) and are used primarily in Europe. In Japan and the United States, BS/DIN chains are used in transmission equipment imported from European countries or for licensed production.

Selection and Handling

Compared to the same-sized ANSI Roller Chains, the power ratings of BS/DIN chains in drive applications (tent curve) are a little lower (Table 1.1).
