This Optibelt RB belt is a Poly-V (multi-rib) belt with a PK profile and a 1520 mm length. It is used on drives that need a flat, flexible belt to wrap small pulleys at speed. Before you fit a new one, check the drive and the sheaves it runs on.

Inspect each sheave for worn grooves, nicks, burrs and built-up debris. A groove that has worn wide or unevenly will let the ribs sit low, so the belt slips even when the tension is correct. Check that the sheaves are aligned and that the belt runs straight in the grooves with no side contact.

Check the bearings, tensioner and any idler for play or roughness, and confirm they turn freely. Look for oil, coolant or grit that can reach the belt path, since these shorten belt life. If the drive uses more than one belt, replace the full set so the load stays even across the ribs.

The same size is also listed under Gates PK 1520. If you are matching a belt already on the machine, read the marking on the back and send that part number, or send the profile and the length you need, and we will confirm the right belt or suggest an equivalent.

We carry Optibelt belts and serve maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America. Send your part number by WhatsApp or email and the team will reply promptly.
