Browning BK50H CLEAR PK Sheave
The Browning BK50H is a heavy-duty single groove sheave engineered for industrial HVACR applications requiring reliable torque transmission and high-fatigue resistance. Constructed from high-grade cast iron, this 4.75" outside diameter pulley is precision-machined to ensure static balance and minimize vibration across high-RPM cycles. Designed for maximum versatility, the BK50H is compatible with H series bushings and accommodates a wide range of power transmission profiles, including 4L, 5L, A, and B belts. Its robust construction ensures concentricity, reducing shaft wear and extending the service life of the drive assembly. When replacing a worn fixed-bore pulley, upgrading to this bushing-style sheave provides a more secure, press-fit connection that simplifies maintenance and field adjustments. This component is essential for maintaining proper belt tension and drive efficiency in commercial blowers and air handling units.
Key Benefits
- Versatile Belt Compatibility: Grooved precisely to accept 4L, 5L, A, and B section V-belts, providing flexibility in belt selection.
- High-Grade Cast Iron Construction: Delivers superior durability and heat dissipation under heavy mechanical loads compared to stamped steel alternatives.
- H-Series Bushing System: Facilitates a secure, tapered fit onto the shaft, reducing the risk of slippage or keyway damage.
- Precision Machined: Ensures a 4.75" OD with accurate tolerances for consistent pitch diameter and optimized drive ratios.
Common Questions
What is the difference between a BK50H and a fixed-bore sheave?
The BK50H requires a separate H-series bushing, allowing it to fit multiple shaft diameters, whereas a fixed-bore sheave is limited to a single permanent size.
Can I use this sheave with both A and B belts?
Yes, the groove geometry is engineered to accommodate A (4L) and B (5L) belts, though the pitch diameter will shift slightly depending on the belt profile used.
Does this include the H-bushing?
No, the BK50H is the sheave only. You must select the appropriate H-bushing based on the specific motor or fan shaft diameter of your equipment.
