The Optibelt 8V KB 2120 is a banded V-belt in the KB SK series, built for drives that use multiple V-grooves and need the belts to stay tied together. Its 5385 mm length and banded construction suit high-torque, heavy-duty equipment where single belts can flip or whip. Confirm fit by matching the part number and length to the drive.
Banded V-belts are common on large fans, blowers, compressors, crushers, and process machinery that run several V-belts side by side. The band keeps the individual belts aligned, which helps control vibration and prevents one belt from rolling out of its groove. If your drive uses a set of V-belts and the existing belts are joined across the top, this is the type of belt to specify.
To confirm the Optibelt 8V KB 2120 fits, read the marking on the back of the old belt and compare the part number and the 5385 mm length. Check the pulley grooves for wear, oil, or debris, and make sure the sheaves are aligned before installing a new set. Ordering the exact part number avoids mismatched lengths that can cause uneven tension across the grooves.

Frequently asked questions
- How do I confirm the 8V KB 2120 is the right belt for my drive?
- Find the marking on the back of the belt you are replacing. If it shows 8V KB 2120 and the measured length matches 5385 mm, it is the same size. You can also send a photo of the marking and the drive setup for confirmation.
- What should I send to request a quote?
- Send the part number 8V KB 2120, the quantity you need, and any drive details you have, such as the pulley diameters or the application. If the old belt is unreadable, send the length and a photo of the drive.
- Can you help if the old belt marking is worn off?
- Yes. Send the length you measure and a photo of the drive and pulleys. The team can compare that against the 8V KB 2120 and suggest the closest match.
