The Optibelt 25 AT5K6 / 4000 AFX is an AT5 profile timing belt in the Alpha Flex series. The profile and the 4000 mm length are the two figures to match against your drive before ordering.
AT5 identifies the tooth profile, and 5 mm is the pitch, so the belt runs on a matching AT5 pulley. The 4000 mm length is stated as the belt length, which sets the center distance the drive can take. If your old belt is marked 25 AT5K6 / 4000 AFX, this is the same profile and length.
For a quote, send the part number 25 AT5K6 / 4000 AFX along with the quantity you need. If the marking on your belt is worn or unreadable, send the profile and length you measured, and the team can confirm the right belt or suggest an equivalent.
