The Optibelt 75 AT20 / 6600 AFX is an Alpha Flex timing belt with an AT20 profile, a 6600 mm length and a 20 mm pitch. Before you fit it, inspect the drive and sheaves so the new belt runs true and lasts.
Check the sheaves for worn grooves, burrs, rust or debris, and confirm they are aligned and securely mounted. Measure the center distance and verify the belt path matches the 6600 mm length and AT20 profile. Any misalignment or damaged sheave will shorten belt life and cause noise or tracking problems.
Confirm the part number on the old belt matches 75 AT20 / 6600 AFX, or that the profile and length match the drive requirements. If you are replacing a belt on a multi-belt drive, fit the full set at the same time so loads stay even.
Send the part number, the belt marking and the drive details by WhatsApp or email, and our team will reply promptly. We can confirm the right belt or suggest an equivalent, and we supply customers across the United States, Canada, Mexico and South America.
