Browning H 1 3/8 5/16 Bushing

The Browning H 1 3/8 5/16 Bushing is a precision-engineered split taper bushing designed for high-torque mechanical power transmission in HVACR and industrial drive systems. Featuring a 1-3/8" bore diameter and a standard 5/16" x 5/32" keyseat, this component ensures a secure, concentric fit on the shaft, effectively eliminating the vibration and slippage common with straight-bore pulleys. The Browning H series bushing utilizes a double-split barrel construction to provide superior gripping power, distributing clamping force evenly across the shaft circumference. Manufactured from high-grade malleable iron or sintered steel, it is compatible with a wide range of Browning sheaves, sprockets, and pulleys. This tapered shaft bushing is essential for contractors performing maintenance on air handlers, cooling towers, and centrifugal pumps, providing a reliable interface between the motor shaft and driven components while simplifying the installation and removal process in tight mechanical spaces.

• High Torque Capacity: The split taper design provides a higher degree of shaft engagement compared to standard QD or straight-bore alternatives.
• Precision Machined: Maintains concentricity to reduce mechanical stress on bearings and drive belts.
• Universal Compatibility: Interchanges with standard H-series hubs across multiple manufacturers for versatile field replacement.
• Reduced Downtime: The 5/16" keyway ensures a keyed mechanical lock, preventing shaft galling and facilitating easier component swaps.

What is the torque rating for a Browning H 1 3/8 bushing?
Rating depends on the mating hub material, but these are typically utilized in light to medium-duty drive applications where a secure friction fit is required.

Can I use an H-series bushing in a QD-style hub?
No, H-series split taper bushings have a specific bolt pattern and taper angle that is not cross-compatible with Quick Detachable (QD) or Taper-Lock systems.

Is the key included with this bore size?
The bushing includes a standard keyseat; however, a separate hardened key is typically required to match the 5/16" x 5/32" specifications for optimal power transfer.
