When you need to replace a timing belt, the first step is to match the belt you are removing. This Optibelt Alpha Flex belt carries the code 75 T20 / 1900 AFX, which identifies its profile and length. Use those two details to confirm it fits your drive.
The T20 profile and 1900 mm length are the key specifications. Check the marking on the back of the old belt: it should show the same profile and length. If the old belt is worn or the marking is unreadable, measure the length along the pitch line and confirm the tooth profile before ordering.
The 20 mm pitch is another fixed dimension of this belt. Do not substitute a different pitch or length without verifying the pulley geometry and center distance. A belt that is too short or too long will not tension correctly and can damage the drive.
If you are unsure whether this is the right belt, send the part number and a photo of the old belt marking to our team. We can help confirm the profile and length, or suggest an equivalent if one is listed.

Frequently asked questions
- How do I confirm this belt matches the one I am replacing?
- Compare the profile and length. The Optibelt 75 T20 / 1900 AFX has a T20 profile and a 1900 mm length. The old belt should carry the same profile and length marking.
- What if the marking on my old belt is worn off?
- Measure the length along the pitch line and identify the tooth profile from the pulleys. If you are unsure, send a photo of the old belt and the drive setup to our team for confirmation.
- Can I use a different length belt if the profile is the same?
- No. The length must match to maintain correct tension and alignment. Changing the length without adjusting the drive can cause poor performance or damage.
