The Optibelt 50 AT20 / 4600 AFX is an Alpha Flex timing belt with an AT20 profile. It measures 4600 mm in length and has a 20 mm pitch, so it is identified by profile and length when matching the belt you are replacing.
To match this belt to the one being replaced, read the marking on the back of the old belt. Confirm the profile is AT20 and the length is 4600 mm. The 50 AT20 / 4600 AFX is the part number to quote when the old marking matches these values.
If the marking is worn or unreadable, measure the old belt and count the teeth to confirm the AT20 profile and 4600 mm length. The 20 mm pitch is the distance between tooth centers. Use these three values to select the correct replacement.
Once you have confirmed the profile, length and pitch, send the part number 50 AT20 / 4600 AFX to our team by WhatsApp or email. We carry Optibelt Alpha Flex timing belts and can help confirm the right belt or suggest an equivalent.
