Browning H 3/8 Bushing

The Browning H 3/8 is a high-precision H Series Split Taper Bushing designed for reliable power transmission in industrial HVACR systems. Built with a 3/8" bore, this component ensures a high-torque connection between shafts and rotating elements like v-belt sheaves, pulleys, or sprockets. Its double-split barrel design is a critical feature for contractors, as it provides a uniform, 360-degree clamp fit that maintains superior concentricity even under heavy vibration. The split taper bushing utilizes a 3/4" per foot taper to create a self-locking mechanical bond, significantly reducing the risk of shaft slippage compared to standard set-screw hubs. As a direct replacement for the legacy H-3/8 model, it maintains the same 2.5" flange diameter and 1.25" length through bore (LTB). The solid flange housing facilitates easy installation and removal using the two 1/4" x 3/4" cap screws, which should be torqued to 95 in-lbs for optimal seating. This mechanical power transmission part is essential for maintaining alignment in fan and blower assemblies.

• Double-Split Barrel: Delivers true concentricity and a positive clamp fit to protect shafts from scarring and fretting corrosion.
• High Torque Capacity: The split taper design ensures the load is distributed evenly, making it ideal for high-cycling HVACR motor applications.
• Direct Interchangeability: Seamlessly replaces older H 3/8 or H-3/8 units in existing Browning sheaves and sprocket drives.
• Simplified Maintenance: Features threaded removal holes in the flange, allowing for quick extraction without damaging the mating pulley or motor shaft.

• Is a keyway required for this specific 3/8" bore size? Small diameter H-series bushings like the 3/8" bore often do not utilize a standard keyway due to wall thickness; the high-pressure taper fit typically handles the rated torque for these fractional applications.
• Can this be used with other manufacturers' sheaves? Yes, this Browning bushing is designed for compatibility with any hub machined to accept a standard H-series split taper profile.
• What is the maximum torque the cap screws should handle? For the 1/4" cap screws included with the H 3/8, always utilize a torque wrench to reach the specified 95 in-lb limit to prevent flange cracking.
