The Optibelt BB 120 DK is a double-V (hexagonal) belt in the BB profile. It drives from both faces, so it suits drives where power is taken off more than one side of the belt run. Confirm the BB profile and the marking on the belt before you order.
Double-V belts are used on drives that need power transmitted from both the top and bottom faces of the belt, such as certain multi-pulley layouts where a single belt wraps pulleys on opposite sides. The BB profile sets the cross-section, and the part number identifies the belt length within that profile.
To confirm fit, read the marking on the back of the belt you are replacing and match it to the Optibelt BB 120. Check that the profile on the belt matches BB and that the drive uses a double-V belt rather than a standard V-belt or a banded belt. If the drive runs more than one belt, inspect the whole set and replace worn belts together so the load stays even.
The same size is also listed under Dayco BB 120 and Gates BB 120. Send the part number and a photo of the belt marking by WhatsApp or email, and we can help confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Read the marking on the back of the belt you are removing. If it matches the Optibelt BB 120 and the profile is BB, that identifies the belt. Also confirm the drive uses a double-V (hexagonal) belt, since a standard V-belt will not fit the same way.
- What should I send to get a quote?
- Send the part number, Optibelt BB 120, and a photo of the belt marking if you have one. If you are not sure of the number, send the profile and the drive details so we can help confirm.
- Is the same size listed under other brands?
- Yes. The same size is also listed under Dayco BB 120 and Gates BB 120.
