The Optibelt Alpha Flex 75 AT20 / 12000 AFX is a timing belt with an AT20 profile and a 12000 mm length. When you are replacing a belt, the most reliable way to match it is to read the marking on the back of the old belt and confirm the profile and length against this page.
The AT20 profile and the 12000 mm length are the key figures to check. If the belt you are removing is marked with the same AT20 profile and the same 12000 mm length, this Optibelt Alpha Flex belt is the direct match for that position. The 20 mm pitch is part of the AT20 profile and is stated here for reference.
Inspect the drive before ordering. Look for worn pulley teeth, misalignment, damaged flanges or tensioner issues that could have caused the original belt to fail. If the old belt is unmarked or the marking is worn away, measure the length and note the tooth profile from the pulleys so the replacement can be confirmed.
If you are unsure, send the belt marking, the profile and the length to our team. We carry the Optibelt Alpha Flex 75 AT20 / 12000 AFX and can confirm it against your application before you request a quote.
