The Optibelt BX 72 Super TX is a cogged classical V-belt in the BX profile, with a length of 1905 mm. To match it to the belt being replaced, compare the part number and the profile marking on the old belt before ordering. This page covers what to check on the drive and what to send for a quote.
Start with the marking on the back of the belt. The old belt should read BX 72; the profile is BX and the length is 1905 mm. If the marking is worn or missing, measure the outside length and confirm the cross-section before selecting a replacement. A cogged belt in the same profile and length seats in the same sheave grooves.
Inspect the drive while the belt is off. Check sheaves for wear, alignment and debris, and confirm the take-up or tensioner has enough travel. Replace belts in sets when the drive uses more than one belt, so all belts share the load evenly. Keep the old belt for comparison until the new one is fitted and tensioned.
The same size is also listed under Dayco BX 72, which can help if you are cross-checking a shelf label or an old purchase record. Send the part number, the profile and the length from the back of the belt, and a photo of the marking if it is faded. The team can confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Match the part number on the old belt: BX 72. Confirm the profile is BX and the length is 1905 mm. If the marking is unreadable, measure the outside length and check the cross-section against the sheave groove.
- Should I replace all belts on the drive at the same time?
- Yes, when the drive uses multiple belts, replace them as a set so they share the load evenly. Mixing a new belt with worn belts can cause uneven tension and premature wear.
- What should I send to request a quote?
- Send the part number BX 72, the profile BX and the length 1905 mm, along with a photo of the marking on the back of the belt if it is still readable. If you have the old belt, include its condition and the drive details.
