This Optibelt Alpha Flex timing belt is identified by the code 50 AT20 / 3800 AFX. It has an AT20 profile, a 3800 mm length and a 20 mm pitch. Send us the part number and we will confirm it for your drive.
Timing belts in this size range are used on industrial drives where the belt has to run at a fixed speed ratio and stay in step with the pulleys. The AT20 profile and 3800 mm length put this belt in the larger end of that work, so it is worth checking the drive carefully before you order.
The most reliable way to confirm fit is to read the marking on the back of the belt you are replacing and match it to the code above. Also check the pulley grooves and the belt width, because a belt of the same length but a different profile will not seat correctly. If the old belt is worn or the marking is unreadable, measure the length and count the teeth if you can, and send those details with your request.
We supply this Optibelt belt to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America. Send the part number by WhatsApp or email and our team will reply promptly. If you are unsure between this belt and another, we can help you confirm the right one for the drive.
