PL (4.70mm pitch) length (mm) + number of ribs

Ribbed belts - Profile PL section (4.70mm pitch). Compressors (> 30 kW), industrial washing machines 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 PL (the pitch ) 1270mm length and 10 is 10 ribs so PL1270/10 Ribs.

The ribbed belt combines the high flexibility of flat belts with the high performance of V-belts. The V-shaped parallel ribs are made from a wear-resistant rubber compound. The high strength tension cord is designed for the many applications of the ribbed belt.

It is embedded in a rubber adhesive mixture and covers the entire width of the ribbed belt. Fibre reinforced, wearresistant rubber compounds ensure quiet operation, oil and heat resistance and a long belt life.
