When you need to replace a timing belt, the most reliable starting point is the belt you are removing. The Optibelt 100 T20 / 4800 AFX from the Alpha Flex series gives you a specific profile and length to match before you order. We carry this belt for maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
This is a timing belt with a T20 profile and a 4800 mm length. The pitch is 20 mm. To match it, read the marking on the back of the old belt and compare each character with the part number above. The profile and length are the critical dimensions: T20 tells you the tooth shape and spacing, while 4800 mm is the datum length. If the old belt is worn or the marking is unreadable, measure the length along the back of the belt and count the teeth to confirm the profile.
A correct match also means checking the drive before installation. Inspect the pulleys for worn teeth, alignment and any debris that could affect belt tracking. Confirm that the replacement belt routes correctly and that the tensioning method follows your equipment documentation. If you are replacing more than one belt on the same drive, it is good practice to replace them as a set so they wear evenly.
