This Optibelt Alpha Flex timing belt is identified by its profile and length: HTD 5M and 4400 mm. The 5 mm pitch defines the tooth spacing, and the 4400 mm length sets the belt's reach on the drive. Use these two values to match the belt you are replacing.
The HTD 5M profile is a synchronous belt profile with a 5 mm pitch. The 4400 mm length is the belt's datum length. Together, they determine whether the belt will fit your drive without changing pulleys or tensioner positions.
When reading the back of an old belt, look for the profile and length. If you find HTD 5M and 4400 mm, this Optibelt Alpha Flex belt is the same size. If the marking is worn, measure the pitch and the overall length, or send us photos of the belt and the drive.
To request a quote, send the part number 100 / 5M 4400 AFX, or the profile and length, via WhatsApp or email. Our team will confirm the belt and can suggest an equivalent if needed.
