This Optibelt Alpha Flex timing belt is identified by its HTD 8M profile and 6400 mm length. It is used in industrial drives where synchronous power transmission is required. Confirm fit by matching both the profile and the length to your existing belt.
The 25 / 8M 6400 AFX is a synchronous belt with an 8 mm pitch and a 6400 mm length. The HTD 8M profile is common in drives that need precise timing and positive engagement. When replacing, check the belt marking on the back for the profile and length, then compare them to this belt.
To confirm fit, measure or read the old belt's profile and length. The profile must be HTD 8M and the length must be 6400 mm. If the marking is worn, send a photo of the belt and the drive pulleys so we can help verify the correct part.
