This Optibelt Alpha Flex belt is a double-sided timing belt with a 4200 mm length, identified by the code 25 DT10 / 4200 AFX. It is built for drives that need synchronized power transmission from both faces of the belt. Use the code on the back of the belt to confirm you are matching the same profile and length.
Double-sided timing belts are common on reversing drives, tandem or dual-shaft arrangements, and any layout where pulleys contact both sides of the belt. The 4200 mm length is the reference dimension for confirming fit on your drive. Because both faces carry teeth, correct routing and pulley engagement matter more than on a single-sided belt.
To confirm fit, read the marking on the old belt and compare it to 25 DT10 / 4200 AFX. Check that the drive uses a double-sided timing belt and that the length matches. If the marking is worn or unreadable, send photos of the belt and the drive layout with your quote request.
