The Optibelt 25 AT10 / 11000 AFX is an Alpha Flex timing belt with an AT10 profile, a 10 mm pitch and an 11000 mm length. This page covers how to match it to the belt you are replacing.
The most reliable starting point is the marking on the back of the old belt. Read the profile, pitch and length, then compare them with the AT10 profile, 10 mm pitch and 11000 mm length of the 25 AT10 / 11000 AFX. If the old belt is worn or the marking is unreadable, measure the length along the belt and confirm the profile by checking that the teeth match the pulley grooves.
Confirm the width and tooth pattern against the pulleys before ordering. The 25 AT10 / 11000 AFX is built to the AT10 profile, so the pulley grooves must match that profile. On long-center drives, check that the belt is routed correctly and that the tension is set according to the drive manufacturer's procedure.
If you are unsure whether this is the correct replacement, send the belt marking or a photo of the old belt by WhatsApp or email. We carry Optibelt and can help confirm the right belt or suggest an equivalent.
