Description

The Optibelt 640 8MDC 21 is a Delta Chain polyurethane timing belt with a 640 mm length. Before you fit it, inspect the drive and sheaves, because worn or misaligned components will shorten the life of any new belt.

Check the sheaves for wear, burrs, or debris in the grooves. Confirm that the shafts turn freely and that the bearings do not have excessive play. Verify that the sheaves are aligned and that the belt path is clear of obstructions.

Measure the old belt and compare it to the 640 mm length of the Optibelt 640 8MDC 21. Confirm that the profile and pitch match the sheaves. If the drive has more than one belt, replace all belts at the same time to keep the load evenly distributed.

When you request a quote, send the part number 640 8MDC 21 and the quantity you need. If you are unsure about the profile, include the belt marking and the sheave details so we can help confirm the right belt or suggest an equivalent.
