OPTIBELT PK 1245 belongs to poly-V belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PK 1245 and any equivalents.
This Optibelt RB belt is a Poly-V (multi-rib) belt with a PK profile and a length of 1245 mm. It is the correct replacement when the belt you are removing carries the same PK 1245 marking.
To match it to the belt being replaced, read the marking on the back of the old belt. The profile must be PK and the length must be 1245 mm. If both match, this Optibelt RB belt is the same size. The same size is also listed under Stark PK 1245 and Gates PK 1245, so you can compare what is already on the drive.
Before ordering, inspect the drive. Check the ribs for cracks, missing ribs or glazing, and confirm the pulleys are aligned and free of debris. A belt that has run hot or slipped may show a polished surface. Replacing a worn belt with the correct PK 1245 size helps restore consistent contact across the ribs.
If you are unsure, send the part number and a photo of the back marking via WhatsApp or email. The team can confirm the right belt or suggest an equivalent. We carry Optibelt belts and reply promptly to quote requests.
