SPROCKET PITCH DIAMETERS
The following table (based on chordal pitch) shows the correct sprocket pitch diameters for all types of chains
having a taut, uniform pitch of one inch.
Sprocket pitch diameters for other uniform chain pitches are directly
proportional to the chain pitch.
To determine sprocket pitch diameters for any other chain pitch, multiply the
tabular diameter by the chain pitch used.
