Parameter description P: pitch, R: roller diameter, N: teeth of sprocket

Pitch diameter PCD = P/(sin180 ° / N)

Outside diameter OD = P/(0.6 + cot180 ° / N)

The following table shows the pitch diameter and outside diameter (pitch 1) of a standard pitch sprocket.

Ex. :

In order to get the pitch diameter and outer diameter of 120 NT(tooth number)25 sprocket, the pitch distance is 7.9789 from the table. So PCD=38.1 * 7.9789=303.98847, or 1 decimal place and round to 303.99.

The outer diameter can be found in the table as 8.516. Therefore, OD=38.10 * 8.516=324.4596, or 1 digit after the decimal point and rounded to 324.

Root circle diameter BD=PCD - R

Maximum root distance (caliper measurement) : CD

For odd teeth: CD=PCDcos90/N - R

For even teeth: CD=BD
