Common sprocket chain roller chain model, common sprocket model size specification table, from 04B to 32B in the range of size, parameters are pitch, roller diameter, tooth size, row spacing and chain width, as well as some calculation methods of sprocket. For the parameters and calculation methods, please refer to the third volume of the Mechanical Design manual.

The chain number in the table multiplied by 25.4/16mm is the pitch value. The suffix A of the chain number indicates the A series, which is equivalent to the A series of the international standard ISO606-82 for roller chains and equivalent to the American standard ANSI B29.1-75 for roller chains; The B series is equivalent to the B series of ISO606-82 and is equivalent to the British roller chain standard BS228-84. In China, the A series is mainly used for design and export, and the B series is mainly used for maintenance and export.

The following is the common sprocket model size table:

Note: In the table, single row refers to single row of sprockets, and multi-row refers to multi-row of sprockets.
