This Optibelt Alpha Flex timing belt is built for synchronous drives that need a long, consistent pitch. The AT20 profile and 11800 mm length suit large, slow-turning equipment where exact tooth engagement matters. Use the markings and the drive layout to confirm it fits before you order.

Timing belts in this size range are common on large industrial drives such as main process rolls, bulk conveyors, and heavy positioning axes. The AT20 profile provides positive engagement, so the belt and pulleys stay in step without slip. Because the length is 11800 mm, a small mismatch in pulley diameter or center distance can add up quickly. Confirm the pulley tooth profile is AT20 and that the required pitch length is 11800 mm.

The easiest check is the old belt. Look for the part number on the back, along with the profile and length. If the marking is worn, measure the pitch length and count the pulley teeth. The belt data here gives a 20 mm pitch and 11800 mm length, which you can compare directly against the drive.

When you request a quote, send the full part number, 100 AT20 / 11800 AFX, and a photo of the belt marking if it is readable. If the drive uses more than one belt, note that as well so the set can be matched. We carry Optibelt Alpha Flex and can help confirm the right belt or suggest an equivalent.
