The Optibelt 4-B 2500 is a banded V-belt from the KB VB series. It has a 4-B profile and a length of 2500 mm. Banded V-belts are used in drives where multiple V-belts run in parallel and must stay aligned.
This belt is built as a single unit with four B-section ribs joined by a tie band. That construction helps keep the ribs from turning over or jumping out of the pulley grooves in drives with pulsating loads or vertical shaft arrangements. It is commonly found on industrial equipment such as compressors, crushers, and large fans where several belts work together.
To confirm fit, check the existing belt marking on the back. You should see the part number 4-B 2500 or the profile 4-B and the length 2500 mm. Also verify the number of ribs and the pulley groove profile match the B-section. If the marking is worn, measure the outside length and compare it to 2500 mm.
When ordering, send the full part number 4-B 2500 and the quantity needed. If you are replacing a set, it is good practice to replace all belts on the drive at the same time so they share the load evenly. Our team can help you confirm the right belt or suggest an equivalent based on your application.

Frequently asked questions
- What does the 4-B profile mean on this Optibelt belt?
- The 4-B profile indicates a banded V-belt with four B-section ribs. The B-section is a standard industrial V-belt profile, and the 4 means four ribs are joined together by a tie band.
- How do I confirm the length of the 4-B 2500 belt?
- The length is 2500 mm. You can verify by checking the marking on the back of the old belt or by measuring the outside length of the belt. The part number itself includes 2500, which corresponds to the length in millimeters.
- Can I replace just one belt in a banded set?
- Banded V-belts are designed to work as a set. Replacing all belts on the drive at the same time helps ensure even load distribution and proper alignment. If you need assistance, send us the part number and we can help you confirm the correct replacement.
