This Gates BB 129 is a double-V (hexagonal) belt from the Hi-Power Dubl-V series. It has a BB profile and a length of 3350 mm. Double-V belts are used on drives that need power transmitted from both sides of the belt, such as reversing or multi-pulley layouts.
To confirm fit, check the belt marking on the back of the old belt. The profile should read BB and the length should match 3350 mm. Because a double-V belt contacts pulleys on both faces, also verify that the drive pulleys are designed for a hexagonal belt and not a standard single-V belt.
The same size is also listed under Optibelt BB 129. If you are replacing a belt on a drive that takes this size, you can compare that reference alongside the Gates part number. For a quote, send the part number BB 129, the profile BB and the length 3350 mm.
We carry the Gates Hi-Power Dubl-V line and can help confirm the right belt for your drive. If you send the old belt marking or the drive details, the team can check the profile and length against this listing.
