Browning 2AK56X 1 3/8 Sheave
The Browning 2AK56X 1 3/8 is a heavy-duty, two groove AK cast iron sheave designed for reliable power transmission in industrial HVACR applications. Engineered with a precision 1 3/8" fixed bore and a 5.45" outside diameter, this pulley is balanced to ensure smooth operation and reduced vibration in belt-driven systems. It is optimized for use with 3L, 4L, and A section V-belts, providing versatility for various motor and fan configurations. The high-grade cast iron construction offers superior wear resistance and thermal stability compared to light-duty alternatives. Contractors often specify the Browning 2AK56 for its consistent pitch diameter and robust fixed bore pulley design, which simplifies installation by eliminating the need for separate bushings. Whether you are replacing a worn drive component or upgrading a blower assembly, this cast iron V-belt sheave ensures maximum torque transfer and long-term alignment stability under high-static pressure loads.
Key Benefits- Dual Groove Design: Supports two-belt drive systems for increased torque capacity and redundancy.
- High-Grade Cast Iron: Provides exceptional durability and heat dissipation for continuous-duty cycles.
- Precision Machined Bore: The 1 3/8 inch bore features an accurate keyway and setscrew for secure shaft attachment.
- Multi-Belt Compatibility: Engineered to match A-section belts and 4L/3L fractional horsepower belts.
- Static Balance: Reduces bearing wear on motors and driven components by minimizing rotational imbalance.
What is the effective pitch diameter of the 2AK56X for A belts?
The pitch diameter for A-section belts is approximately 5.10 inches, which is critical for calculating precise drive ratios and RPM outputs.
Can this sheave be used with 5L or B-section belts?
No, this sheave is specifically grooved for 3L, 4L, and A belts. Using wider B-section belts will result in improper seating and premature belt failure.
Does this unit require a separate bushing for installation?
No, the Browning 2AK56X 1 3/8 is a fixed bore sheave, meaning the 1-3/8" diameter is machined directly into the hub for a direct-to-shaft fit.
