The Optibelt 16 AT5K6 / 2500 AFX is an Alpha Flex timing belt with an AT5 profile, a 2500 mm length and a 5 mm pitch. When replacing a belt, match these three markings to the belt on the drive before you order.
Start with the marking on the back of the old belt. The profile, length and pitch printed there should read AT5, 2500 mm and 5 mm to correspond with this Optibelt belt. If the old belt is worn or the marking is unreadable, measure the drive and confirm the same three values.
The 16 AT5K6 / 2500 AFX is a timing belt, so it is selected by profile and length rather than by cross-section. AT5 describes the tooth profile, 2500 mm is the belt length and 5 mm is the pitch. Confirm all three against your drive documentation or the belt you are removing.
If you are unsure whether this is the correct replacement, send the part number from the old belt, the profile, length and pitch, and a photo of the marking. The MR team will confirm the match or suggest an equivalent. We carry the Optibelt Alpha Flex line and reply to quote requests by WhatsApp or email.
