The Optibelt 25 / 5M 3000 AFX is an Alpha Flex timing belt with an HTD 5M profile, a 3000 mm length and a 5 mm pitch. Before you fit it, take a few minutes to inspect the drive and the sheaves. A worn or misaligned drive will shorten the life of any new belt.
Check the sheaves for worn grooves, burrs, corrosion or debris, and confirm they are clean and aligned. Look at the bearings and the shaft for play, and verify that the tensioner moves freely. If the old belt failed early, the cause is often in the drive rather than the belt itself.
Confirm the part number on the back of the old belt matches 25 / 5M 3000 AFX. The profile is HTD 5M, the length is 3000 mm and the pitch is 5 mm. If the marking is unreadable, measure the length and count the teeth to identify the correct replacement.
Send the part number and the quantity you need by WhatsApp or email, and we will reply promptly. If you are unsure about the profile or length, include a photo of the old belt marking and the drive arrangement. We can help confirm the right belt or suggest an equivalent.
