Browning BK57X1 Sheave
The Browning BK57X1 Sheave is a professional-grade cast iron V-belt pulley engineered for high-performance power transmission in HVACR and industrial applications. This single groove sheave features a 5.45-inch outside diameter and is precision-machined with a 1-inch fixed bore to ensure a secure, direct-to-shaft fit. Designed for versatility, the BK series utilizes a combination groove profile compatible with 4L, 5L, A, and B belts, allowing technicians to standardize inventory while maintaining precise pitch diameters (4.9" for A-belts; 5.4" for B-belts).
Constructed from high-tensile cast iron, the Browning BK57X1 offers superior vibration dampening and heat dissipation compared to pressed steel alternatives, extending the service life of both the motor and the belt. The finished bore includes a standard keyway and setscrew, providing a reliable mechanical lock for high-torque startups. Whether you are replacing a worn blower pulley or configuring a custom air handler drive, this Browning BK sheave delivers the concentricity and balance required for quiet, efficient operation.
Key Benefits:- Universal Belt Compatibility: The unique combination groove supports 4L, 5L, A, and B section belts, offering maximum field flexibility.
- Durable Cast Iron Construction: Provides excellent wear resistance and thermal stability for continuous-duty HVACR equipment.
- Precision Finished Bore: The 1-inch bore is accurately machined with a 1/4" x 1/8" keyway for immediate installation without additional boring.
- Optimized Performance: Enhances drive efficiency and reduces belt slip in commercial refrigeration and ventilation systems.
- What are the specific pitch diameters for this sheave? For A/4L belts, the pitch diameter is 4.9 inches; for B/5L belts, the pitch diameter is 5.4 inches.
- Can this be used with dual-belt setups? No, the BK57X1 is a single-groove component. For multi-groove requirements, consider the 2BK series.
- Is the keyway included in the 1-inch bore? Yes, this sheave features a standard internal keyway and setscrew for a secure mechanical connection.
