The Optibelt 640 8MDC 12 is a Delta Chain polyurethane timing belt with a 640 mm length. Before you fit it, take a few minutes to inspect the drive and sheaves so the new belt runs correctly from the start.
Check the sheaves for wear, burrs, corrosion or debris in the grooves, and confirm they are clean and aligned. Look at the shaft bearings and tensioner for play, noise or roughness, and correct any issues before installation. A drive that is out of alignment or has worn components can shorten the life of a new belt.
Verify that the part number on your old belt matches 640 8MDC 12, and note the profile and length. If you need help confirming the right belt or a suitable equivalent, send the complete marking and photos of the drive to our team by WhatsApp or email.
We carry the Optibelt 640 8MDC 12 for maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America. Request a quote by part number and we will reply promptly.
