Banded V-Belts

Banded V-Belts

Sometimes called multi-groove belts, banded V-belts are recommended for applications where speed fluctuations, misalignment, shock, and vibration might cause single belts to whip, turn over, or fall off the pulley. They consist of two or more single V-belts held together with a reinforced backing that distributes the stress evenly across the belts and prevents the belt from turning over in the pulley. Banded V-belts can be used in wide belt drives that are designed for multiple single belts and are better suited than single V-belts for applications with stacked loads. When replacing a belt on a pulley, make sure the style (or series) and width of the belt match the pulley.

Classic Banded V-Belts (B-Section)

These classic banded V-belts are used in a wide range of industrial and commercial power transmission applications. They are a good choice for applications with unusual or demanding conditions, such as reverse-bending and twisted drive systems.

High-Torque Narrow Banded V-Belts (3V, 5V, & 8V Sections)

The individual sections of these belts have a narrow profile that lets them sit deep in the pulley groove. This provides more support for the belt in applications with high shock loads and maximizes the surface contact between the belt and the pulley groove for improved friction and torque compared to classic banded V-belts.
