The Optibelt 4-D 9906 is a banded V-belt from the KB VB series, built for drives that need multiple belts to work as a single unit. Its 9906 mm length matches the original specification, so you can replace like for like without modifying the drive.
Before fitting, inspect the sheaves for wear, misalignment, or debris. Worn grooves can shorten the life of any new belt, and misaligned sheaves cause uneven tension across the band. Check that all grooves are clean and free of rust or buildup, and confirm the sheave diameters match the drive requirements.
Because this is a banded V-belt, the individual ribs are joined together, which keeps them from turning over or jumping out of the grooves. That construction is useful on drives where vibration or pulsating loads would otherwise cause single belts to misbehave. When you replace a banded belt, always fit a complete new band rather than mixing old and new belts on the same drive.

Frequently asked questions
- What does the 4-D 9906 part number tell me?
- It identifies an Optibelt banded V-belt from the KB VB series with a length of 9906 mm. Use this number when requesting a quote or comparing against the belt you are replacing.
- Can I replace just one belt in a banded set?
- No. Banded V-belts are designed to operate as a set, so replace the complete band. Mixing a new belt with old ones can lead to uneven tension and premature failure.
- What should I check on the drive before installing a new belt?
- Inspect the sheaves for wear, misalignment, and buildup in the grooves. Clean or repair any issues before fitting the new belt, and verify that the sheave diameters and groove profile match the belt.
