Poly-V belts

Poly-V belts have longitudinal V-ribs on a flexible body: they combine the flexibility of a flat belt with the grip of a V-belt. They transmit power in little space, at high speeds and with low noise, and are seen in pumps, fans, compressors and machine tools. They are selected by profile, number of ribs and length, data obtained from the pulley and center distance.

The designation carries all three. In SKF's PHG 10PJ1194, 10 is the number of ribs, PJ is the profile and 1194 is the length in millimeters; PHG 10PJ1321 and PHG 10PJ2083 read the same. The PJ profile has a rib pitch of 2.34 mm, so it does not cross with other profiles like PK or PL even if they look similar at first glance.

They are used in drives that need a stable ratio and low noise: centrifugal pumps, induced draft fans, screw compressors, machine tools and air conditioning equipment. To identify an old belt, count the ribs, measure the pitch between them and take the length.

In this subcategory we work with SKF. Send us the full code via WhatsApp or email or, if you don't have it, the profile, number of ribs and length. With that data we will indicate the correct belt and quote you promptly.
