This Optibelt 25 / 14M 3150 AFX belt is an HTD 14M timing belt from the Alpha Flex series. The profile and length are the two details that determine fit on a synchronous drive, so confirm both against the belt you are replacing.
The 14M profile is a synchronous belt profile with a 14 mm pitch. The code also gives a 3150 mm length, which is the datum length for this belt. On a timing drive, the profile controls how the teeth seat in the pulleys, and the length sets the center distance. A belt with the same profile but a different length will not run correctly, and neither will a belt with the same length but a different profile. Read both numbers from the old belt before ordering.
The belt is marked 25 / 14M 3150 AFX. The 14M and 3150 match the profile and length above, and AFX identifies the Alpha Flex series. If the back of the old belt is worn or the marking is hard to read, measure the length and count the teeth to confirm the profile and pitch.
