The Optibelt PH 1290 RB is a poly-V (multi-rib) belt with a PH profile and a 1290 mm length. It is used on drives that take a flat, multi-rib belt running on matching grooved pulleys. This page covers how to match it to the belt you are replacing.
Start with the belt on the drive. Read the marking on the back of the old belt: you are looking for the profile, PH, and the length, 1290 mm, along with the part number PH 1290. If the back is worn or dirty, clean it and read it under good light. Compare what you find with the data on this page before you order.
Next, check the drive itself. The pulley grooves must match the PH profile, and the belt must sit correctly in them. Look at the pulleys for wear, chips or buildup in the grooves, and check the alignment of the pulleys and the tensioner. A belt that is the right profile and length can still run poorly on a drive that needs attention.
If the marking is unreadable, measure the old belt and note the profile and length, then send the part number PH 1290 and the drive details to our team. We can confirm the belt or suggest an equivalent. Send your request by WhatsApp or email and we will reply promptly.
