Poly-V belts

Poly-V belts are power transmission elements that combine the flexibility of a flat belt with the grip of a V-belt. They are used in equipment that requires transmitting torque with limited space and high speeds, such as pumps, fans, compressors, and machine tools. To select a Poly-V belt, consider the profile (the letter that defines the pitch and rib shape), the number of ribs, and the outer or pitch length. These data come from the pulley and the available space in the drive.

In the MR Accesorios Industriales catalog we work with SKF Poly-V belts. An example code is PHG 12PJ584: the initial letters identify the family and compound type, the number before PJ indicates the number of ribs (12), PJ is the profile, and the final number is the length in millimeters (584). Knowing this nomenclature allows you to read the label and order the correct belt without depending on physical samples.

Poly-V belts are used in drives where a stable transmission ratio and low noise are required. They are common in centrifugal pumps, induced draft fans, screw compressors, machine tools, and air conditioning equipment. They are also used in the food industry and process plants, where cleanliness and operational continuity are critical.

To request a quote for a Poly-V belt, we need the complete code (for example, PHG 12PJ584), or the profile, number of ribs, and length. If you do not have the code, we can help you identify it from the pulley: count the grooves, measure the pitch diameter, and the center distance. With that data we check the cross-reference and provide you with the available option.

At MR Accesorios Industriales, with more than 80 years in Buenos Aires, Argentina, we advise maintenance and purchasing teams to help them find the right belt. In addition to Poly-V belts, we offer timing belts, V-belts, pulleys, chains, and power transmission components. Write to us via WhatsApp or email with the code or dimensions, and we will provide you with a quote promptly.
