This page covers the Optibelt PJ 508 RB, a Poly-V (multi-rib) belt with profile PJ and a length of 508 mm. Use it when you need to match a belt already on the drive rather than start a new selection.
The most direct way to match this belt is to read the marking on the back of the belt you are replacing. If it reads PJ 508, this Optibelt RB belt matches that profile and length. The same size is also listed under Gates PJ 508, so you can compare the two listings if your drive currently runs that brand.
Confirm the belt is a Poly-V (multi-rib) type and that the profile is PJ before ordering. The length is 508 mm. If the old belt is worn or the marking is unreadable, measure the outside circumference and count the ribs so the replacement agrees with the drive.
Inspect the pulleys while the belt is off. Check for worn grooves, debris, or misalignment, since these can shorten the life of any replacement. If you are unsure between this belt and another listing, send the part number and a photo of the old belt marking to our team for confirmation.
