OPTIBELT 85 / 8M 5200 AFX belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 85 / 8M 5200 AFX and any equivalents.
This Optibelt Alpha Flex timing belt is identified by the code 85 / 8M 5200 AFX. The profile is HTD 8M and the length is 5200 mm, with a pitch of 8 mm. Those three values are the ones to match against your drive before you order.
The profile and length do the real work here. HTD 8M is the tooth form, so the pulley grooves must be cut to suit that profile. The 5200 mm length is the datum for the run, and the 8 mm pitch is the spacing between tooth centers. If your existing belt is marked with the same profile and length, this is the direct size to specify.
The code on the back of the old belt is the fastest way to confirm what you need. Read the profile, the length and the part number off the belt and send them to us. We carry Optibelt and can check the 85 / 8M 5200 AFX against what came off the drive, or help you find the right belt if the marking is worn.
For a quote, send the part number 85 / 8M 5200 AFX by WhatsApp or email. If you have the old belt in hand, include a photo of the back marking and the pulley diameters. That lets us confirm the profile and length before you commit to the order.

- How do I confirm this is the right belt for my drive?
- Read the marking on the back of the old belt. If it shows HTD 8M and 5200 mm, or the code 85 / 8M 5200 AFX, it is the same size. Send us that marking and we will check it against the Optibelt listing.
- What should I send to get a quote?
