This Optibelt Alpha Flex timing belt is identified by its AT5 profile and 2100 mm length. The 5 mm pitch defines the tooth spacing along the belt. Use these three values to confirm the belt matches your drive before requesting a quote.
The AT5 profile is a synchronous belt tooth form. The 2100 mm length is the datum length of the belt, and the 5 mm pitch is the distance from one tooth center to the next. The part number 50 / AT5 2100 AFX combines these identifiers so you can match the marking on your existing belt.
When replacing a timing belt, read the profile, length and pitch from the back of the old belt or from the drive documentation. If the marking is worn or unreadable, measure the belt length and count the teeth to verify the pitch. Send the complete part number, 50 / AT5 2100 AFX, along with the application details for a quote.
Timing belts should be inspected for tooth wear, cracking, glazing and tension loss. Replace the belt if any of these conditions are present. On drives with multiple belts, replace all belts at the same time to maintain even load sharing.
