Description
The Browning AK46H is engineered for professionals who require more reliability than a standard “fixed-bore” pulley can offer. By utilizing the H-Series Split Taper Bushing, this sheave provides a true 360-degree grip on the shaft, virtually eliminating the shaft damage and keyway “vibration-wobble” common in lower-end components. Each AK46H is statically balanced at the factory to ensure smooth, quiet operation—critical for protecting sensitive motor bearings and ensuring long belt life. Its close-grain cast iron construction allows for precision machining to tight tolerances, making it the ideal partner for 3L, 4L, and A-Series V-belts in air handlers, pumps, and light-duty machinery.
Key Features
- H-Bushing Versatility: The bushed design allows this single sheave to fit shaft diameters from 3/8″ to 1-1/2″ by simply changing the bushing (sold separately).
- Vibration-Free Operation: Statically balanced to provide the smooth performance required for high-efficiency HVAC and industrial blowers.
- Multi-Belt Compatibility: Precision-machined grooves are designed to accommodate 3L, 4L, and A-Section (including Gripnotch) V-belts.
- Durable Cast Iron: High-quality gray cast iron provides excellent wear resistance and thermal dissipation compared to stamped steel alternatives.
- Rugged Enamel Finish: Baked-on enamel protects the sheave from corrosion in humid mechanical rooms or outdoor environments.
