Description
Boost your drive system’s torque and efficiency with the Browning 2AK74H. This heavy-duty, two-groove sheave is engineered for high-demand fractional horsepower (FHP) environments, such as large commercial HVAC blowers, air handlers, and industrial machinery. Specifically designed to accommodate 4L, A, and 3L belt sections, this pulley offers the versatility needed for diverse power transmission setups. Machined from high-grade, fine-grained cast iron, the 2AK74H is built for long-term durability and resistance to wear. Every unit is statically balanced at the factory to eliminate vibration, ensuring quiet operation and extending the lifespan of your belts and motor bearings. Using the precision “H” Split Taper Bushing system, it provides a secure, concentric fit that prevents shaft marring and simplifies installation.
Key Features
- Dual-Groove Design: Allows for two-belt drives, providing higher horsepower capacity and redundancy for critical systems.
- Precision Balancing: Statically balanced to provide smooth, vibration-free performance even at high RPMs.
- Multi-Belt Compatibility: Optimized for A (4L) and 3L belt series, making it a versatile choice for various drive ratios.
- Close-Grain Cast Iron: Rugged construction offers superior heat dissipation and maximum resistance to groove wear.
- Split Taper Mounting: Designed for use with an “H” Bushing, offering a larger bore range (3/8″ to 1-1/2″) and a tighter shaft grip than fixed-bore alternatives.
- Industrial Grade Finish: Gray powder-coat/paint finish provides enhanced corrosion resistance in damp or industrial environments.
