When a timing belt needs replacing, the fastest way to identify the correct part is to read the marking on the back of the old belt. This Optibelt Alpha Flex belt is marked 25 AT5 / 3800 AFX. It has an AT5 profile, a 3800 mm length and a 5 mm pitch.
Before you order, clean the back of the old belt and photograph the full marking. Look for the profile and length: AT5 and 3800 mm identify this belt. If the old marking is worn or missing, check the drive drawing or the machine manual for the same profile and length. The belt width code is part of the part number, so confirm it matches the pulley width.
This is a timing belt, also called a synchronous belt. The AT5 profile and 5 mm pitch define how the teeth engage the pulleys. The 3800 mm length is the datum length. When you request a quote, send the complete part number 25 AT5 / 3800 AFX and the quantity you need. If you are replacing a belt on a drive with multiple belts, order the full set so all belts on the drive share the same age and wear.

Frequently asked questions
- How do I confirm the belt I need?
- Read the marking on the back of the old belt. If it shows 25 AT5 / 3800 AFX, that is the part number to request. If the marking is not clear, check the drive documentation for the profile and length.
- What does the part number tell me?
- The number identifies the belt by its profile, length and width code. This belt has an AT5 profile and a 3800 mm length. The 5 mm pitch is the distance between tooth centers.
- Can I replace just one belt on a multi-belt drive?
- For drives with multiple belts, it is common practice to replace all belts in the set at the same time. This helps maintain even tension and wear across the drive.
