The Optibelt 25 AT5K6 / 1600 AFX is a timing belt from the Alpha Flex series. Its AT5 profile and 1600 mm length identify the drive it fits, so you can match the belt to the pulley groove and center distance before you order.
The profile is AT5, a metric timing belt tooth form. The pitch is 5 mm, and the overall length is 1600 mm. These three values are what you compare against the old belt or the drive specification. If the profile and length agree, the belt is the correct size for that position.
When you request a quote, send the complete part number 25 AT5K6 / 1600 AFX. If you are replacing a belt that is worn or unmarked, include the profile and length you measured, or send a photo of the back of the belt. We can confirm the AT5 profile and 1600 mm length against your data and suggest an equivalent if needed.
For drives that use more than one belt, order the full set at the same time so all belts share the same profile, pitch and length. This belt is a timing belt, so it is used where synchronous tooth engagement is required. Inspect the pulleys for wear or damage before installation.
