The Optibelt 20 / 8M 3800 AFX is an Alpha Flex timing belt with an HTD 8M profile, a 3800 mm length and an 8 mm pitch. When you read the marking on the back of the belt you are replacing, this is the code to match.
The marking on a timing belt typically shows the profile and the length, and on this belt that reads HTD 8M and 3800 mm. The 20 / 8M 3800 AFX code identifies the belt in the Optibelt Alpha Flex series, so the cleanest way to confirm the correct replacement is to compare the old marking directly with this listing.
If the back of the old belt is worn, dirty or cut away, the profile and length are the two details to capture. This belt uses the HTD 8M profile with an 8 mm pitch and a length of 3800 mm. Send those values, or a photo of the marking, and we can confirm the match or suggest an equivalent.
For maintenance and purchasing teams, ordering by the full part number avoids confusion between similar profiles and lengths. We carry the Optibelt 20 / 8M 3800 AFX and quote by part number through WhatsApp or email.
