The Optibelt RB PK 990 is a Poly-V (multi-rib) belt with a PK profile and a length of 990 mm. To match it to the belt being replaced, confirm the profile and the length on the old belt, then compare them with these values.
The marking on the back of a Poly-V belt typically shows the profile and the length. On this Optibelt RB belt, the profile is PK and the length is 990 mm. If the marking on your old belt reads PK 990, this is the same size. If the marking is worn or missing, measure the length along the belt and count the ribs to confirm the profile before ordering.
Poly-V belts are used on drives where several ribs run in matching grooves. A belt with the wrong profile or length will not sit correctly in the pulleys. Check the pulleys for wear, oil or debris, and make sure the ribs are not cracked or missing. If the drive uses more than one belt, replace all belts at the same time so the load is shared evenly.
