This Optibelt Alpha Flex timing belt is identified by the code 100 / 5M 2100 AFX. It uses the HTD 5M profile with a 5 mm pitch and a 2100 mm length. For maintenance and engineering teams, the code on the belt is the fastest way to confirm the correct replacement.
Timing belts in the HTD 5M profile are used in synchronous drives where the belt teeth mesh with pulley grooves to maintain position. This Optibelt Alpha Flex belt is built for those drives, with a 5 mm pitch and a 2100 mm length. The 100 / 5M 2100 AFX code is the reference point for selection.
To confirm fit, read the marking on the back of the old belt and match every part of it. If the existing belt shows 100 / 5M 2100 AFX, this is the same size. If the marking differs, send the complete code, the pulley tooth count, and the drive arrangement to MR. The team can verify the HTD 5M profile and 2100 mm length against your application.
When replacing a timing belt, inspect the pulleys for wear, check alignment, and confirm the belt is correctly tensioned. Replacing other drive components at the same time can prevent repeat failures. Send the belt code by WhatsApp or email to request a quote for the Optibelt 100 / 5M 2100 AFX.
