This Optibelt Alpha Flex belt is a timing belt in the AT5 profile with a 10200 mm length and a 5 mm pitch. Long synchronous belts like this one are used on drives where two shafts sit far apart and the belt has to keep the driven side in step with the driver. Send us the part number and our team will confirm it against your drive.
The AT5 profile is a metric synchronous profile, so fit starts with the pulley. Check that the pulleys on the drive are cut for AT5 and that the belt width matches the pulley face. Then confirm the length: 10200 mm is the figure to compare against your old belt or against the drive drawing. A belt that is too short will not go on without forcing the shafts; one that is too long will not let you set tension.
On a belt this long, the marking on the back is the quickest way to identify what is on the machine. Read the profile, the length and the part number off the old belt before you order, and note the condition of the pulleys and the tensioning arrangement at the same time. If the old belt has failed early, the drive itself is usually worth a look before the replacement goes on.
When you request a quote, send the full part number, 25 AT5 / 10200 AFX, along with the belt width if it is marked, the pulley tooth count and the center distance. A photo of the back of the belt and of the drive helps us check the details.

Frequently asked questions
- How do I confirm this belt fits my drive?
- Match three things: the AT5 profile on the pulleys, the 10200 mm length and the 5 mm pitch. Compare those against the marking on your old belt or the drive documentation.
- What should I send with a quote request?
- Send the part number 25 AT5 / 10200 AFX, the belt width if it is marked on the back, the pulley tooth counts and the center distance. A photo of the drive is useful as well.
- Where is a belt of this type used?
- Timing belts are used on synchronous drives where the driven shaft has to stay in step with the driver. On a belt of this length, the two shafts are set well apart and the belt runs over the pulleys between them.
