Description
OPTIBELT PK 1285 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 1285 and any equivalents.
This Optibelt RB belt is a Poly-V (multi-rib) belt with a PK profile and a length of 1285 mm. The PK profile identifies the rib pitch, and 1285 mm is the datum length you match to the drive.
When you select by profile and length, the two values that matter are PK and 1285 mm. PK sets the rib geometry that engages the pulley grooves, and 1285 mm sets the belt length around the drive. Confirm both against the marking on the old belt or the drive documentation before you order.
This is a multi-rib belt, often called a serpentine belt, used where a single belt drives several accessories from one path. The RB series is the Optibelt line for this construction. If the belt has been running in a set with others, inspect the full set and replace together where the drive calls for it.
To request a quote, send the part number PK 1285, the profile PK and the length 1285 mm by WhatsApp or email. If you are unsure whether this is the right belt for the drive, include the old belt marking or a photo of the routing, and the team can help confirm the right belt or suggest an equivalent.
