The Optibelt 25 / 14M 6398 AFX is a timing belt in the Alpha Flex series with an HTD 14M profile. This page is for maintenance and purchasing teams matching it to the belt being replaced. Use the profile, the 6398 mm length and the 14 mm pitch to confirm it against the old belt's marking before requesting a quote.
To match this belt to the one being replaced, start with the marking on the back of the old belt. The Optibelt 25 / 14M 6398 AFX carries an HTD 14M profile, a length of 6398 mm and a 14 mm pitch. These three values are the core of the match. If the old belt shows the same profile and length, this part number is the one to quote.
When the old marking is worn or unreadable, work from the drive instead. Measure the belt length and confirm the profile from the pulley grooves. The 14M profile and 6398 mm length identify this belt. If the drive runs two or more belts, replace them as a set so the load stays even across the drive.
