How Banded V Belts Differ from Standard Belts and When to Specify Them for Industrial Use
Multi-belt drives , where several parallel V belts run side-by-side on matched pulleys , are common in high-power industrial applications. While matched individual belts serve many such applications adequately, banded V belts address a specific set of problems that arise in drives subject to vibration, shock loading, or variable tension across the belt width. Understanding when banded belts offer a genuine engineering advantage over standard individual belts guides correct specification decisions. What Banded V Belts Are Banded V belts (also called joined belts or tie-rib belts) consist of multiple V belt ribs moulded together under a common fabric backing that spans the full width of the belt assembly. Rather than installing three or four individual V belts on parallel grooves, a single banded belt assembly replaces them, with the ribs maintaining the correct centre-to-centre groove spacing throughout. The construction uses the same cross-section profiles as indivi...
