Browning BK47H Sheave
The Browning BK47H Sheave is a precision-engineered single groove cast iron pulley designed for heavy-duty power transmission in HVACR blower assemblies and industrial fan drives. With a 4.45" outside diameter and a 4.1" pitch diameter for B-belts, this BK cast iron sheave utilizes H Series bushings to ensure a secure, slip-free concentric fit on the shaft. Engineered for versatility, the Browning BK47H is compatible with 4L, 5L, A, and B section belts, providing contractors with a reliable solution for various drive ratios. The high-grade ASTM class 30-35 cast iron construction offers superior dampening characteristics and wear resistance compared to stamped steel alternatives. Balanced to ISO G16 quality standards, this sheave minimizes vibration in high-RPM applications, extending the life of motor bearings and belts. When replacing a fixed bore sheave with this split taper bushing design, verify the required torque specifications to maintain drive integrity under high static pressure loads.
Key Technical Benefits:- Interchangeable H-Bushing System: Allows for flexible bore sizing and easy removal from the shaft during maintenance.
- Multi-Belt Compatibility: Engineered to run A belt, B belt, 4L belt, and 5L belt profiles without specialized adjustments.
- Cast Iron Durability: Provides excellent heat dissipation and structural rigidity for continuous duty cycles.
- Precision Balancing: Reduces harmonic resonance and mechanical stress on the drive train.
- What is the maximum RPM for the BK47H? In standard HVAC applications, these sheaves are typically rated for 6500 FPM rim speeds; always calculate the drive velocity before installation.
- Does this include the bushing? No, the H Series bushing is sold separately to allow for specific shaft diameter matching.
- Can I use this for a 5/8" or 7/8" shaft? Yes, the Browning BK47H is compatible with any H-bushing ranging from 3/8" to 1-1/2" bore sizes.
