This Optibelt Alpha Flex timing belt is identified by the code 50 T20 / 10400 AFX. It has a T20 profile and a length of 10400 mm, with a pitch of 20 mm. It is a synchronous belt intended for drives that require exact timing between shafts.
This belt is used where a synchronous drive must maintain a fixed relationship between the driven and driving pulleys. The T20 profile and 10400 mm length make it suited to large, long-center-distance drives. Confirm fit by checking the belt marking on the back of the old belt, the pulley groove profile, and the measured length.
When requesting a quote, send the full code 50 T20 / 10400 AFX, the profile T20, and the length 10400 mm. If the marking is worn, measure the pulley pitch diameter and the center distance so we can help confirm the correct belt. We carry Optibelt Alpha Flex belts and can review your drive details before you order.
For drives with more than one belt, replace all belts at the same time and check pulley alignment and tension. Inspect the pulleys for wear or damage that could affect belt seating. If you need help reading a partial marking or matching a drive, contact us by WhatsApp or email with the part number and any photos of the old belt.
