The Optibelt 25 / 5M 4200 AFX is an Alpha Flex timing belt with an HTD 5M profile and a 4200 mm length. The most reliable way to order the correct replacement is to match the marking on the back of the belt you are removing.
Read the full code from the old belt: 25 / 5M 4200 AFX. Confirm the profile is HTD 5M, the length is 4200 mm and the pitch is 5 mm. If the marking is worn or missing, measure the belt width and the pitch length and send those figures with photos of the drive.
Send the part number, the belt marking and any photos of the pulleys and routing by WhatsApp or email. We carry the Optibelt Alpha Flex line and will confirm the 25 / 5M 4200 AFX or suggest the closest equivalent based on the data you provide. For drives with more than one belt, order the full set so all belts share the same age and load history.
Before fitting, inspect the pulleys for wear, check alignment and verify the tension. A new timing belt on worn or misaligned components will not reach its expected service life. If you are unsure whether the 25 / 5M 4200 AFX matches your drive, send the details and we will help you confirm it.

Frequently asked questions
- How do I confirm that the 25 / 5M 4200 AFX is the right belt for my drive?
- Check the marking on the back of the belt you are replacing. It should read 25 / 5M 4200 AFX. Also confirm the profile is HTD 5M, the length is 4200 mm and the pitch is 5 mm. If the marking is unreadable, measure the pitch length and width and send those figures with photos of the drive.
- What information should I send to request a quote?
- Send the part number 25 / 5M 4200 AFX, the belt marking from the old belt, the quantity, and any photos of the drive and pulleys. If you need help identifying the belt, include the width and pitch length you measured. We reply by WhatsApp or email.
- Should I replace all belts on a multi-belt drive at the same time?
- Yes. On drives that use more than one belt, replacing the full set at once keeps tension and load sharing even. Mixing new and used belts can cause the new belt to carry more load and wear faster.
