Browning BK120X 1 3/16 Sheave
The Browning BK120X 1 3/16 is a heavy-duty, single-groove cast iron sheave designed for reliable power transmission in industrial HVACR applications. Engineered for high-torque environments, this cast iron pulley features an 11.75-inch outside diameter and is precision-machined for a 1 3/16" fixed bore. It is compatible with a wide range of drive configurations, specifically accommodating A belt, B belt, 4L, and 5L series V-belts. The BK120X sheave is statically balanced to minimize vibration, extending the service life of motor bearings and connected blower shafts. Its robust construction ensures dimensional stability under significant thermal loads, making it an ideal replacement part for commercial air handlers and ventilation systems. By utilizing a 1 3/16 inch bore size with a standard keyway, this sheave provides a secure fit for HVAC motor pulleys requiring precise alignment and consistent rotational velocity in belt-driven assemblies.
Key Benefits
- Versatile Belt Compatibility: Designed to work seamlessly with 4L, 5L, A, and B section V-belts for maximum application flexibility.
- Durable Cast Iron Construction: High-grade cast iron sheave material provides superior wear resistance and heat dissipation compared to stamped steel alternatives.
- Precision Balanced: Minimized radial runout and axial wobble reduce mechanical stress on the 1 3/16 fixed bore interface.
- Corrosion Resistance: Finished with a protective coating to withstand moisture and environmental contaminants common in mechanical rooms.
Common Questions
What is the pitch diameter for this sheave?
The pitch diameter varies by belt type: it is approximately 11.0" for A belts and 11.4" for B belts, essential for calculating accurate drive ratios.
Does this sheave come with a set screw?
Yes, this fixed bore sheave includes standard set screws to secure the pulley and keyway to the motor or fan shaft.
Can I use this on a 1.1875 inch shaft?
Yes, 1 3/16" is the decimal equivalent of 1.1875", ensuring a standard fit for common NEMA motor shafts.
