PJ Ribbed belts
To help you identify your belt if it is not marked, we advise the following. Step 1. Identification of the pitch, so measure from the middle of one rib across to the middle of the next rib to it. Step 2. Count the number of ribs. Step 3. Measure the circumference of the belt to determine the length (all the way around). So three things only, the pitch, the number of ribs and the length. To endorse the measurement of the pitch of the ribs, measure the width of the belt and then times X the number of ribs by the pitch, this will confirm. Example PH (the pitch ) 1075mm length and 7 is 7 ribs so PH1075/7 Ribs.
