The Optibelt B KB 3250 is a banded V-belt from the KB VB series, listed at a 3250 mm length. It is built for drives that run several V-belts side by side, where the band holds the ribs together as one unit. Before you fit it, take a few minutes on the drive itself.
Banded belts are matched to a set, so the sheaves matter as much as the belt. With the drive locked out, check each groove for wear, rust, burrs and buildup. A groove that has worn wide lets the belt sit low and slip, and a new banded belt will not correct that. Look at the sheave alignment as well, since a banded belt is less tolerant of misalignment than single belts.
Inspect the rest of the drive while you are there: bearings for play or noise, the take-up for the range it still has, and the guard for anything that could rub. If the old belt failed early, the cause is usually on the drive rather than in the belt. Send us the part number B KB 3250 by WhatsApp or email and we will confirm the belt or suggest an equivalent for your application.
When ordering, the marking on the back of the old belt is the fastest reference, along with the drive it runs on and the number of ribs in the set. That lets us check the profile and the 3250 mm length against what you need.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Send the part number B KB 3250, the marking on the back of the old belt, and the drive it runs on. We will check the profile and the 3250 mm length and reply with a quote.
- Should I replace the whole set at once?
- On a banded drive, the belts in a set work together. Replacing only part of a worn set leaves the banded belt carrying an uneven load, so plan on the full set.
- What should I check on the sheaves before fitting?
- Check each groove for wear, rust and burrs, confirm the sheaves are aligned, and look at bearings and take-up. Worn or misaligned sheaves will shorten the life of a new banded belt.
