The Optibelt B KB 4500 is a banded V-belt with a 4500 mm length. To match it to the belt you are replacing, read the marking on the back of the old belt and compare the profile and length. If the numbers and profile agree, this is the belt to quote.
Banded V-belts tie two or more V-belts together with a common top layer. That construction keeps the ribs aligned and shares the load across the set, which is why banded belts are common on drives where a single belt would whip or turn over. The B KB 4500 uses the B profile and measures 4500 mm, so it fits drives built for that profile and center distance.
When you inspect the drive, check each sheave groove for wear and any debris. A worn groove can let a new belt sit too deep and slip. Also confirm the belt is not twisted and that the ribs run straight in the grooves. If the old belt is too worn to read, send photos of the drive and the belt cross-section.
For a quote, send the part number B KB 4500, the quantity, and the marking from the old belt if you have it. We carry Optibelt belts and can confirm the profile and length against your application.

Frequently asked questions
- How do I confirm the B KB 4500 matches my old belt?
- Read the marking on the back of the old belt. It should show the profile and length. If it reads B KB 4500, the profile and length match. If the marking is unreadable, measure the top width and the outside length, or send a photo of the belt and the drive.
- What should I check on the drive before installing a banded V-belt?
- Inspect the sheave grooves for wear, cracks, or embedded debris. Check that the sheaves are aligned and that the take-up can still adjust. Worn grooves or misalignment can shorten belt life and cause the ribs to run at different depths.
- What information do you need to quote the B KB 4500?
- Send the part number B KB 4500, the quantity you need, and the marking from the old belt if you have it. If you are unsure of the profile or length, include photos of the belt and the drive so we can confirm.
