In this article, you will learn more about the ISO standard SPROCKET

ISO

ISO standard R606 dictates sprocket uniformity for most European and African nations. This standard is in relation to British Standard Chain, which is dimensionally different than chains meant for ANSI sprockets.
ISO Sprockets have large pitches that are measured in sixteenths of an inch, but are expressed in metric units. British Standard Chain was developed before American-styled chain, but was limited in its development by what materials were readily available as roller chains evolved. The outer plates of an ISO chain are taken from the chain size one level above the application requirements. This led to bulkier, heavier chain with a longer fatigue life that is still used today. So, ISO standard R606 only includes single, double, and triple-strand sprockets.

In ISO naming conventions, the ‘B’ indicates adherence to European standards. An ISO sprocket may also feature a number as a suffix, which will indicate the number of chain strands. For example, 16B-2 sprocket will feature a pitch of one inch along with a double-strand spool.

ISO standard R606 ,specifies the characteristics of short-pitch precision roller and bush chains with associated sprockets suitable for the mechanical transmission of power and allied applications. It covers dimensions, tolerances, length measurement, preloading, minimum tensile strengths and minimum dynamic strength.
