This Optibelt Alpha Flex timing belt is identified by its 30 mm width, HTD 8M profile, and 1904 mm length. The 8 mm pitch and HTD 8M profile make it a synchronous belt for drives that require precise positioning and speed control.
The part number 30 / 8M 1904 AFX combines the belt's width, profile, and length. The 30 mm width and 8 mm pitch are fixed by the HTD 8M profile. The 1904 mm length is the datum length for this belt, so it must match the drive's required length for proper fit and tension.
When replacing an existing belt, confirm the profile, pitch, width, and length on the old belt's back. The marking 30 / 8M 1904 AFX identifies this exact Optibelt Alpha Flex belt. If the old belt is worn or unreadable, measure the length and check the pulley groove profile to confirm HTD 8M.
