The Optibelt XPA 1257 is a cogged narrow V-belt in the Super X-Power M=S series. It has an XPA profile and a length of 1257 mm. Before you fit it, take a few minutes to inspect the drive and sheaves.
Check sheave grooves for wear, rust, or embedded debris. Worn grooves can cause a new belt to sit too deep and slip. Confirm that sheaves are aligned and that the belt tensioner moves freely. If you are replacing a belt that failed early, look for the cause before installing the Optibelt XPA 1257.
This belt is a cogged narrow V-belt, often called a wedge belt. The cogged construction is common on drives with small pulleys. The XPA profile and 1257 mm length must match the old belt. Read the marking on the back of the old belt to confirm the part number.
When you request a quote, send the part number XPA 1257 and the quantity you need. If you are unsure, send a photo of the old belt marking and the sheave dimensions. The team can help confirm the right belt for your drive.

Frequently asked questions
- How do I confirm the Optibelt XPA 1257 fits my drive?
- Check the marking on the back of the old belt. It should show the profile and length. The XPA profile and 1257 mm length must match. If the old belt is unreadable, measure the sheave grooves and send the details for confirmation.
- Should I replace all belts on the drive at the same time?
- On a multi-belt drive, replace all belts as a set. Mixing new and worn belts can cause uneven tension and early failure. This applies to the Optibelt XPA 1257 when used with other belts.
- What should I inspect before installing a new belt?
- Inspect sheave grooves for wear, rust, or debris. Check alignment and tensioner operation. Correct any issues before fitting the new belt to avoid premature failure.
