1. Transmission Chains
(1) Carbon steel sprockets with plain bores. (Sintered metal or cast iron are sometimes used.) (2) Carbon steel sprockets with finished bores, keyway, and setscrews. TAPER-LOCK ® and QD ® bores are also available. (3) 304 stainless steel sprockets with plain bores. (4) Engineered plastic sprockets with plain bores. (5) POWER-LOCK ® sprockets, which do not require a keyway or setscrew.

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).
