This page covers the Optibelt PL 991 RB, a Poly-V (multi-rib) belt with a PL profile and a length of 991 mm. If you are replacing a worn belt, start by reading the marking on the back of the old one and matching profile and length to this listing.
On many drives the old belt still carries its marking on the back. Read it before the belt is removed or discarded, note the profile and the length, and compare them with the PL profile and 991 mm length given here. A match on both points is what identifies the correct belt for the drive.
The same size is also listed under Gates PL 991, so when you are working from a marking in that form the size can be cross-checked against this Optibelt belt. We carry the Optibelt PL 991 RB as a Poly-V (multi-rib) belt in the PL profile.
For a quote, send the part number Optibelt PL 991 RB by WhatsApp or email. If you are unsure between two markings, include a photo of the back of the old belt and the drive it runs on, and the team can help confirm the right belt or suggest an equivalent.
