The Optibelt 3VX 425 KB is a banded V-belt in the KBX series, with a length of 1080 mm. Banded construction ties multiple V-belts together so they run as one unit on multi-groove drives. This belt is used where a single belt would be prone to flipping, stretching or whipping on high-ratio or pulsating drives.
Typical service is on drives that need several V-belts side by side: fans, blowers, compressors, mixers and similar industrial equipment. Because the ribs are joined by a common band, the belt stays aligned in the sheave grooves and resists the turnover that can occur with individual belts on shock-loaded or vertical-shaft drives. The 3VX profile is a narrow wedge cross-section, and the 1080 mm length is the datum length for this part.
To confirm fit, read the marking on the back of the old belt and compare it with the part number. Check the sheave grooves for wear, and verify that the number of ribs on the replacement matches the drive. If you are unsure, send the belt marking, the drive make and model, and the sheave diameters and groove counts to our team.
When replacing a banded belt, inspect the entire drive: sheave alignment, groove condition, and tension. A worn or misaligned sheave will shorten the life of any new belt. If the old belt has stretched or the drive has been modified, confirm the required length before ordering.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Read the part number on the back of the existing belt. If it matches 3VX 425 KB and the length is 1080 mm, it is the same size. Also check that the number of ribs and the sheave groove count match.
- Can I replace individual V-belts with a banded belt?
- A banded belt is designed for drives that use multiple belts. It keeps the belts aligned and prevents flipping. If your drive currently uses individual belts, check the sheave grooves and the drive requirements before switching.
- What information should I send for a quote?
- Send the part number 3VX 425 KB, the quantity, and any drive details such as sheave diameters and groove counts. Our team will confirm the belt or suggest an equivalent.
