The Optibelt 16 AT5 / 4200 AFX is an Alpha Flex timing belt with an AT5 profile, a 5 mm pitch and a 4200 mm length. It is built for synchronous drives where the belt teeth mesh with pulley grooves to keep the driven shaft in step with the drive.
Timing belts of this type are common on industrial equipment that needs synchronized motion rather than friction drive: positioning axes, indexing tables, linear actuators, packaging and printing machinery, and similar drives. The AT5 profile and 5 mm pitch identify the tooth form and spacing, while the 4200 mm length sets the belt's path around the pulleys.
To confirm fit, read the marking on the back of the old belt and compare it with 16 AT5 / 4200 AFX. Check the pulley tooth profile, the belt width and the length, and inspect the pulleys for worn teeth or debris before installing a replacement. If the marking is worn away, send photos of the belt and pulleys along with your measurements.
We carry the Optibelt Alpha Flex line and supply this 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 confirm the belt or suggest an equivalent.

Frequently asked questions
- How do I confirm this belt fits my drive?
- Match the marking on the back of your existing belt to 16 AT5 / 4200 AFX, then verify the pulley profile, belt width and length. If the marking is unreadable, send photos and measurements for confirmation.
- What does the AT5 profile mean for my application?
- AT5 is the tooth profile, and the 5 mm pitch is the distance between tooth centers. Together they determine which pulleys the belt will mesh with, so the pulley groove form must match.
- Can you help if I only have the old belt?
- Yes. Send the part number if it is legible, or photos and dimensions of the old belt. Our team will identify the correct Optibelt belt or suggest an equivalent.
