This Optibelt 4-D 6858 is a banded V-belt from the KB VB series, with a length of 6858 mm. Banded construction ties multiple V-belts together so they run as a single unit on drives that use matched sets. It is used where load is shared across several belt strands and where keeping those strands aligned matters.
Banded V-belts are common on heavy-duty industrial drives: crushers, mixers, large fans, compressors and similar equipment where a single belt would not carry the load. The band holds the individual strands at a fixed spacing, which helps prevent one belt from flipping or running at a different tension than the others. If your drive was built for a banded set, replacing it with loose belts can lead to uneven wear and vibration.
To confirm fit, read the marking on the back of the old belt and compare it with 4-D 6858. Check the profile and the 6858 mm length against your drive documentation, and count the number of strands in the banded set. If the marking is worn or unreadable, send us the drive make and model, pulley dimensions and a photo of the belt and nameplate. We will help confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I know if this banded V-belt fits my drive?
- Compare the part number on the back of your existing belt with 4-D 6858, and check the profile and 6858 mm length against your drive records. If you cannot read the old marking, send photos of the belt, pulleys and drive nameplate and we will help confirm.
- Can I replace a banded belt with individual V-belts?
- Banded belts are designed to run as a set with the strands held at a fixed spacing. Replacing them with loose belts can cause uneven tension, flipping and faster wear. Use a banded belt where the drive specifies one.
- What information do you need for a quote?
- Send the part number 4-D 6858, the quantity, and any drive details you have, such as the equipment make and model or pulley dimensions. If you are unsure of the number, a photo of the old belt marking helps.
