Browning 4R5V80 4-Groove 5V Bushing Bore V-Belt Sheave Pulley 8" OD

Browning 4R5V80 4-Groove 5V Bushing Bore V-Belt Sheave Pulley 8" OD

The Browning 4R5V80 is a four-groove, 5V-section bushing bore V-belt sheave (pulley) with an approximate 8-inch outer diameter. It accepts a QD or taper-lock style bushing (sold separately) for mounting to a shaft, making it adaptable to a range of shaft sizes without changing the sheave itself. The sheave is cast iron construction, designed for use in multi-belt V-belt drive systems transmitting power between motors, fans, pumps, compressors, and similar industrial machinery.

Applications

5V-section bushing bore sheaves like the Browning 4R5V80 are standard power transmission components used throughout industrial and commercial equipment — including HVAC fans and blowers, pumps, air compressors, conveyor drives, and motor-to-machine power transfer systems. The 5V belt section is a wedge-type profile that handles higher torque loads in a more compact cross-section compared to classical A/B/C belts, making it common in higher-horsepower drive systems. Browning is one of the most widely recognized names in V-belt sheave manufacturing in North America, and their QD (Quick Detachable) bushing bore system has been an industry standard since the mid-twentieth century, allowing the same sheave to fit a wide range of shaft diameters simply by swapping the bushing. This sheave is appropriate for four-belt 5V drive configurations and is typically paired with a matching sheave on the driven machine.
