SKF Poly-V belts with PK profile are used in drives that need to transmit power quietly at high speed and with significant speed ratios. They merge the suppleness of a flat belt with the strength of a V-belt. We supply these belts in multiple rib counts and lengths so they fit multi-rib pulleys. For a quote, just share the code marked on the old belt.
Reading the belt code is straightforward. The letters PHG come first, indicating the product line. Next comes a number that tells you how many ribs the belt has: PHG 6PK885 has 6 ribs, PHG 8PK1090 has 8 ribs. The digits after PK give the outside length in millimeters: 885 mm, 1090 mm, and so on. So PHG 7PK1610 is a 7-rib belt, 1610 mm long. The PK profile is a thin-section type, designed for pulleys of small diameter.
You will find these belts in machine tools, compressors, pumps, fans and other transmission equipment in manufacturing plants. They also appear in automotive accessories such as alternators, power steering and air conditioning. Because they transmit power in a compact space, they are common where room is tight and speed is high.
When selecting a Poly-V belt, check the number of ribs on the pulley and the outside length you need. Make sure the profile is PK and that the pulley has the same rib pitch. During installation, align the pulleys and set the correct tension: too much tension speeds up wear on bearings and the belt itself; too little causes slipping and heat. Inspect the pulleys and replace the belt if you see cracks or wear.
Poly-V belts are identified by profile and rib count, so a PK belt of similar specifications can be swapped between brands as long as the standardized dimensions match. Still, manufacturers may differ in compound and construction. To be sure of compatibility, request a quote with the exact code and confirm the technical data.
To request a quote for SKF Poly-V belts, send us the complete belt code on WhatsApp—for example, PHG 6PK885—or tell us the number of ribs and the length. We will help you find the right belt for your equipment. If you cannot locate the code, a photo or the pulley measurements will let us identify it for you.

Frequently asked questions
- How do I identify the Poly-V belt I need?
- Check the code stamped on the belt: it shows ribs and length. For instance, 6PK885 means 6 ribs and 885 mm. If the code is unreadable, measure the outside length and count the pulley ribs. With that information we can quote you.
- What does the PK profile mean on a Poly-V belt?
- PK is a standardized designation for thin-section belts with V-ribs. It is used in drives that require high speed and small-diameter pulleys. The rib count and length are part of the code.
- Can I replace a Poly-V belt from another brand with an SKF one?
- Yes, provided the profile, number of ribs and length are the same. Standardized dimensions allow interchangeability. We recommend checking pulley condition and alignment before installing the new belt.
