This Optibelt Alpha Flex belt is a double-sided timing belt with a 5400 mm length. Double-sided timing belts drive pulleys from both faces, which suits serpentine layouts where the belt must turn more than one driven pulley in opposite directions. This page covers where that construction is used and how to confirm the fit before you order.
Double-sided timing belts are common on reversing drives, twin-camshaft arrangements and any layout where one belt must rotate two shafts in opposite directions. The teeth on both faces engage pulleys on either side, so the drive can be compact without an idler to twist the belt. This Optibelt Alpha Flex belt is identified by the code 25 DAT10 / 5400 AFX and a length of 5400 mm.
To confirm the fit, read the marking on the back of the old belt and match the code and length exactly. Check that the drive uses toothed pulleys on both sides of the belt, since a double-sided belt will not run correctly on a flat or V-groove pulley. Count the pulley teeth and confirm the belt profile engages cleanly before ordering.
Send the full code, 25 DAT10 / 5400 AFX, along with the length and the equipment it runs on. A photo of the back marking and the pulley arrangement helps confirm the correct belt. If you are unsure, our team can review the details and help you match the belt to the drive.
