This Optibelt Alpha Flex timing belt is identified by its AT20 profile and 1800 mm length. The 20 mm pitch defines the tooth spacing, so it must match the pulley groove exactly. Use these three values to confirm the belt before you request a quote.
The AT20 profile is a synchronous belt profile. The 1800 mm length is the datum length for this belt. The 20 mm pitch is the distance from one tooth center to the next. All three values appear in the part number 100 AT20 / 1800 AFX, so you can compare them directly with the marking on your old belt or with your drive documentation.
When you request a quote, send the full part number 100 AT20 / 1800 AFX and confirm the profile, length and pitch. If the marking on the back of your belt is worn or unreadable, measure the pitch and the length and include those figures. We carry the Optibelt Alpha Flex line and can help you confirm the correct belt for your drive.
