The Optibelt 3VX 450 KB is a banded V-belt in the KBX series with a length of 1143 mm. This page is written for maintenance and purchasing staff who need to confirm it against the belt currently on the drive. The most reliable check is the marking on the back of the old belt.
Start by reading the old belt. A banded V-belt carries its part number on the back, and the characters and spacing should match the Optibelt 3VX 450 KB exactly. If the marking is worn or the belt is missing, measure the outside length of the belt run and compare it with the 1143 mm figure given here. Note that this belt is a banded construction, so the ribs are joined across the top; a set of single V-belts is not a direct substitute where a banded belt was fitted.
Check the drive before ordering. Confirm the number of ribs in the band, the pulley grooves and the condition of the sheaves. A worn or misaligned pulley will shorten the life of any replacement, banded or not. If the drive runs several belts, replace the full set at the same time so the load is shared evenly.
When you have the marking and the drive details, send the part number 3VX 450 KB to our team by WhatsApp or email. We carry the Optibelt KBX series and will confirm the belt against your application, or suggest a suitable equivalent if the exact item does not match your drive.

Frequently asked questions
- How do I confirm this is the right belt?
- Read the marking on the back of the belt you are replacing. If it matches 3VX 450 KB, the belt is the correct one. If the marking is unreadable, measure the outside length and compare it with the 1143 mm length given for this belt.
- Can I replace a banded belt with individual V-belts?
- A banded V-belt such as the 3VX 450 KB has its ribs joined across the top. Individual belts are not a direct substitute where a banded belt was specified, because the band keeps the ribs aligned and shares the load across the drive.
- What should I send for a quote?
- Send the part number 3VX 450 KB, the quantity you need, and any details from the drive such as the number of ribs and pulley grooves. A photo of the old belt marking also helps us confirm the match.
