on . Posted in Gear

gear center to center dist 1Center-to-center distance, abbreviated as CC, is the center distance of two spur gears is the distance from the center shaft of one spur gear to the center shaft of the other.


Center-to-center Distance formula

\(\large{ CC = \frac{ PD_a \;+\; PD_b }{2} }\) 
Symbol English Metric
\(\large{ CC }\) = center-to-center distance \(\large{in}\) \(\large{mm}\)
\(\large{ PD_a }\) = pitch diameter gear a \(\large{in}\)


\(\large{ PD_b }\) = pitch diameter gear b  \(\large{in}\) \(\large{mm}\)
