The Optibelt 25 T5 / 8400 AFX is a timing belt in the Alpha Flex series. It uses the T5 profile with an 8400 mm length and a 5 mm pitch. This page gives you the profile and length data you need to confirm the belt against your drive.
The T5 profile and 8400 mm length are the two dimensions that decide fit on a synchronous drive. The 5 mm pitch sets the tooth spacing along the belt, so the pulley grooves must match that pitch. Confirm the profile and length on the drive before you order.
The 25 in the part number is the belt width code from the manufacturer. The T5 profile, 8400 mm length and 5 mm pitch are the values to check against the old belt and the drive layout. If you are replacing a belt on a drive with more than one belt, replace the full set and check pulley wear at the same time.
To request a quote, send the part number 25 T5 / 8400 AFX, the profile T5, the length 8400 mm and the pitch 5 mm. If you are unsure of the exact belt, send the marking on the back of the old belt and a photo of the drive. We carry Optibelt and can help confirm the right belt or suggest an equivalent.

Frequently asked questions
- What do the profile and length tell me about this belt?
- The T5 profile and 5 mm pitch define the tooth shape and spacing, and the 8400 mm length defines the belt circumference. The pulley grooves and the drive center distance must match these values.
- How do I confirm this belt against the one on my drive?
- Read the marking on the back of the old belt and compare the profile, length and pitch. If the marking is worn, measure the old belt and check the pulley profile before ordering.
- What should I send to request a quote?
- Send the part number 25 T5 / 8400 AFX, or the profile T5, length 8400 mm and pitch 5 mm. A photo of the drive and the old belt marking helps confirm the correct belt.
