The Bestorq BB Series are wrapped, classical hexagonal V-belts engineered for drives requiring power transmission on both sides of the belt. Their double-V profile allows the belt to flex in both directions, providing stable performance and long service life in serpentine and reverse-bend applications.
Easy Replacement & Compatibility
Bestorq BB belts interchange with hex (double-V) belts from major brands (e.g., Gates®, Goodyear®, Carlisle®). To replace, simply match your existing belt number (e.g., BB46) to the equivalent Bestorq BB part.
Specifications: Section BB with nominal top width 0.66 in and height 0.55 in. Available lengths from 50.70 in (BB46) up to 304.70 in (BB300).
