The Optibelt 100 AT10 / 4200 AFX is an Alpha Flex timing belt with an AT10 profile, a 10 mm pitch and a 4200 mm length. When you are replacing a belt, the marking on the back of the old belt is the best starting point. Use the part number and the profile and length values to confirm you are matching the same belt.
Read the old belt before you remove it. The back of the belt carries the part number, and on this belt that is 100 AT10 / 4200 AFX. The AT10 profile and the 10 mm pitch identify the tooth form, while 4200 mm is the length. Write these down and compare them with the belt you are ordering.
If the marking is worn or unreadable, measure the length and check the tooth profile against the pulley. The replacement must have the same profile, pitch and length. Send the part number, the profile, the pitch and the length to our team by WhatsApp or email and we will confirm the belt or suggest an equivalent.
