PK ribbed belts
The most common ribbed belt, for vehicle engines, compressors, garden equipment and general machinery. PK belts have ribs spaced 3.56mm apart. Choose the number of ribs, or search by the code on your old belt, such as 6PK1200.
Choosing the right PK belt
Three things decide which PK belt you need: the section, the number of ribs and the length.
- Reading the code6PK1200 is 6 ribs, PK section, 1200mm long. The older inch code for the same belt is 472K6.
- Checking the sectionMeasure the width and divide by the number of ribs. If the answer is about 3.56mm, it’s a PK belt.
- Cut to orderBelts are cut to your rib count, so they can’t be returned unless faulty. Check the size before ordering, or call us to confirm.
