The Optibelt BB 124 DK is a double-V (hexagonal) belt in the BB profile. When you need to replace a worn double-V belt, matching the profile and the part number on the old belt keeps the drive running as designed. This page covers how to confirm the BB 124 is the correct replacement for your application.
Start by reading the marking on the back of the belt you are replacing. Look for the profile (BB) and the part number (BB 124). If the old belt is unmarked or the printing has worn off, measure the top width and the thickness to confirm the BB profile, and check the length against your drive documentation. The Optibelt BB 124 DK is a double-V belt, so it drives from both sides; a standard V-belt will not work in its place.
The same size is also listed under Dayco BB 124 and Gates BB 124. If you find one of those numbers on the old belt, the Optibelt BB 124 DK is a direct size match. For a quote, send the part number, the quantity, and a photo of the old belt's marking if you have one. Our team can confirm the BB 124 or suggest an equivalent based on the data you provide.

Frequently asked questions
- How do I know if the Optibelt BB 124 DK is the right replacement?
- Check the marking on the belt you are replacing. If it shows BB 124, or if the same size is listed under Dayco BB 124 or Gates BB 124, the Optibelt BB 124 DK matches that profile and part number. If the marking is unreadable, measure the profile and length to confirm.
- Can I use a standard V-belt instead of this double-V belt?
- No. The Optibelt BB 124 DK is a double-V (hexagonal) belt, which drives from both sides. A standard V-belt only drives from one side and is not a substitute.
- What information should I send for a quote?
- Send the part number BB 124, the quantity you need, and a photo of the old belt's marking if it is readable. If you have the drive details or a measurement of the old belt, include those as well so we can confirm the correct belt.
