The Optibelt D 390 KB is a banded V-belt built for drives that use several belts running as one unit. Before you fit it, inspect the sheaves and the rest of the drive so the new belt starts on a sound basis. We carry this belt and quote by part number.
Check each sheave groove for wear, rust, and buildup. Worn grooves let the belt sit too deep, so it slips and wears fast. Confirm the sheaves are aligned and the grooves are clean and dry. Spin the drive by hand and look for rough bearings or a seized idler.
A banded belt ties its ribs together, so it runs as a set rather than as separate belts. If one rib is damaged, the whole band is affected. Replace the banded belt as a complete unit, and check that the drive takes a banded V-belt of this profile and length before ordering.
Send the part number D 390 KB by WhatsApp or email. If you are unsure of the profile or length, send the marking on the back of the old belt and a photo of the drive. We reply promptly and can help confirm the right belt.

Frequently asked questions
- What should I check on the drive before fitting this belt?
- Inspect the sheave grooves for wear, rust, and buildup, and confirm the sheaves are aligned. Check bearings and idlers for roughness or seizure, and clean the grooves before the belt goes on.
- Can I replace just one rib of a banded belt?
- No. A banded V-belt runs as one joined unit, so it is replaced as a complete band. If one rib is damaged, fit a new band.

- Send the part number D 390 KB by WhatsApp or email. If you need help confirming the belt, include the marking on the back of the old belt and a photo of the drive.
