The Optibelt 25 AT5K6 / 11000 AFX is an Alpha Flex timing belt with an AT5 profile and an 11000 mm length. The AT5 profile and the 11000 mm length are the two dimensions that determine whether this belt fits your drive.
When you select by profile and length, the AT5 profile defines the tooth form and the 5 mm pitch, while the 11000 mm length sets the belt's reach around the pulleys. Both values are stated directly in the part data, so you can compare them with the belt you are replacing or with the drive's specification.
This is a synchronous belt, so it transmits motion through tooth engagement rather than friction. The Alpha Flex series and the AT5 profile belong to the Optibelt range we carry. If you are matching an existing belt, read the marking on the back of the old belt and note the profile, the length and the part number.
