The Optibelt BX 103 KB is a banded V-belt from the KBX series, with a 2692 mm length. The banded construction ties multiple V-belts together, which helps keep them running as one unit on drives that use several belts side by side. This page covers what the profile and length mean for your selection.
The BX profile is a narrow V-belt cross-section, often called a wedge belt. Narrow profiles carry more load per belt width than classic V-belts, so they are common where space is tight and power demand is steady. The KB designation in the series name indicates a banded belt, meaning the individual belts are joined by a top cover. That joint keeps the set from whipping or turning over, and it helps maintain matched tension across all the ribs in the drive.
The 2692 mm length is the datum length for this belt. When you measure a used belt, it will be stretched and worn, so the number on the old belt back is the reliable reference. Check that the profile matches BX and that the length matches 2692 mm before ordering. If the drive uses a set of banded belts, replace the full set at once so the load stays even across the bands.

Frequently asked questions
- What does the BX profile mean for my drive?
- BX is a narrow V-belt profile, also called a wedge belt. It fits pulleys machined for that cross-section. The banded KB construction means the belt is built as a joined set, so it runs as one unit on multi-groove drives.
- How do I confirm the 2692 mm length?
- Read the marking on the back of the old belt. If it shows BX 103 KB, the length is 2692 mm. Do not rely on a tape measure across a worn belt, since stretch and wear affect the reading.
- What should I send to get a quote?
- Send the part number BX 103 KB, the brand Optibelt, and the quantity you need. If you have a photo of the old belt marking or the drive setup, include it so we can confirm the profile and length.
