The Browning AK59H Sheave is a high-performance 1-groove V-belt pulley engineered for reliable power transmission in fractional horsepower applications. Constructed from close-grain cast iron, this AK Series cast iron sheave is precision-machined and statically balanced to ensure smooth, vibration-free operation in demanding HVACR environments. It features a 5.75" outside diameter and is designed to interface with H series split taper bushings, allowing for a versatile bore range of 3/8" to 1-1/2".

This fixed-pitch v-belt sheave is optimized for 3L, 4L, and A-section belts, providing a 5.7-inch pitch diameter for A-belts and a 5.16-inch pitch diameter for 3L belts. The split taper bushed design ensures a secure, concentric fit on the shaft, reducing mechanical slip and extending the service life of both the motor and the driven components. Whether you are performing a field replacement or a new system installation, the Browning AK59H provides the durability required for industrial power transmission and commercial air handling units.

Key Benefits:

• Broad Compatibility: Engineered for use with 3L, 4L, and A-section classical V-belts.
• Precision Balance: Each unit is statically balanced to eliminate harmonic vibrations and protect motor bearings.
• Durable Construction: Manufactured from high-tensile cast iron for enhanced resistance to wear and deformation.
• Standardized Fit: Utilizes H-series bushings, making shaft mounting and removal efficient for technicians.
• Technical Tolerances: Finished with close-to-spec machining for consistent belt engagement and drive efficiency.

Common Questions:

• What belts are compatible with the AK59H? This sheave is optimized for A-section (4L) and 3L belts commonly found in light-duty HVAC applications.
• What is the difference between outside diameter and pitch diameter? While the outside diameter (OD) is 5.75", the pitch diameter (PD) for an A-belt is 5.7", which is the point where the belt effectively transfers power.
• Does this sheave require a bushing? Yes, this is a bushed sheave that requires an H-series split taper bushing (sold separately) to match your specific motor shaft diameter.
