The Optibelt 4-C 3550 is a banded V-belt from the KB VB series, with a length of 3550 mm. When you are replacing a worn belt, matching the existing part number is the most direct way to confirm the correct replacement. This page covers what to check on the belt you are removing and what to send for a quote.

Start by reading the marking on the back of the belt you are replacing. The 4-C 3550 identifies this banded V-belt, and the length is given as 3550 mm. Confirm that the number on your old belt matches before requesting a quote, since a different length or a different banded construction will not interchange even if it looks similar at a glance.

A banded V-belt is typically used where multiple V-belts run as a set on the same drive. If the drive uses more than one belt, inspect all of them together: wear, elongation and cracking usually appear across the set, not on a single belt. Replacing the full set helps keep the drive running evenly.

If the marking is worn off or unreadable, send us what you can see. A photo of the belt and the drive, along with the machine or drive details, is often enough for our team to help confirm the right belt or suggest an equivalent. We carry Optibelt belts and serve customers across the United States, Canada, Mexico and South America.
