The Optibelt 3-B 1550 is a banded V-belt from the KB VB series, with a length of 1550 mm. It is the part number to work from when you are replacing a belt that carries the same marking. If your drive runs more than one belt, this is where you confirm the match before you order.
Start at the old belt. Read the marking printed on the back of it and compare it with 3-B 1550. A banded V-belt ties two or more V-belts together with a common top cover, so the number of ribs in the band matters as much as the length. If the old belt is worn or the marking has rubbed off, measure the belt cross-section and the length, and note how many ribs the band carries.
On banded drives, belts are normally replaced as a matched set rather than one at a time. Mixed wear across a set changes how the load is shared, so check every belt in the drive while you have it apart. Inspect the sheaves at the same time for worn grooves, and check that the take-up has enough travel to tension a new set.
Send the part number 3-B 1550 and the quantity you need by WhatsApp or email, and our team will confirm the belt and reply with a quote. If the number on your old belt does not match exactly, send a photo of the marking and the drive details and we will help you confirm the right belt.

Frequently asked questions
- How do I confirm this is the belt I am replacing?
- Read the marking on the back of the old belt and compare it with 3-B 1550. Also confirm the number of ribs in the band and the length, since a banded belt must match the drive on both.
- Should I replace all the belts in the drive at once?
- On a banded drive, the belts work as a set. Replacing the set together keeps the load shared evenly across the sheaves instead of letting the new belt carry more than its share.
- What do I send to get a quote?
- Send the part number 3-B 1550 and the quantity you need by WhatsApp or email. If the old marking is unclear, send a photo of it along with the drive details and we will help confirm the match.
