Browning H 1 7/16 Bushing

The Browning H 1 7/16 Bushing is a high-performance split taper bushing engineered for critical power transmission applications in HVACR and industrial systems. Featuring a precision-machined 1 7/16" bore and a standard 3/8" x 3/16" keyseat, this component ensures a high-torque, non-slip connection between shafts and rotating elements like sheaves, pulleys, or sprockets. Its double-split barrel design provides superior concentricity, effectively gripping the shaft with a uniform clamp fit that minimizes vibration and extends bearing life. Built from high-strength cast iron or sintered steel, it utilizes a 3/4" per foot taper for a self-locking mechanical fit. This H-series bushing is a technician favorite for its ease of installation and removal, maintaining alignment even under heavy radial loads. Whether you are performing a pulleys and sheaves replacement or a new drive system install, this bushing offers the reliable torque transmission and shaft locking required for 24/7 mechanical operations.

Key Benefits

• Maximum Concentricity: The double-split barrel ensures a 360-degree grip, reducing runout and protecting high-rpm drive components.
• High Torque Capacity: Engineered for industrial power transmission, delivering 95 in-lbs of recommended cap screw torque for secure positioning.
• Easy Maintenance: The split taper design allows for quick removal and repositioning without damaging the 1-7/16 inch shaft.
• Durable Construction: Manufactured from robust materials to resist wear in demanding HVAC air handler and blower assemblies.

Common Questions

How do I ensure the bushing is properly seated?
Clean the shaft and 1 7/16" bore thoroughly, then align the 3/8" x 3/16" keyway. Tighten the cap screws sequentially in a circular pattern to approximately 95 in-lbs to achieve the necessary shaft locking force.

Will this fit any H-series sheave?
Yes, this Browning H bushing is standardized to fit all H-series industrial sheaves and sprockets, ensuring seamless HVAC drive component compatibility across different manufacturers.

What happens if I over-torque the cap screws?
Excessive torque can lead to flange stress or fracture. Always use a calibrated torque wrench to meet the Browning bushing specs for a safe and concentric fit.
