Browning B 1 5/8 Bushing

The Browning B 1 5/8 Bushing is a precision-engineered split taper bushing designed for high-torque power transmission in industrial HVACR systems. Built with a double-split barrel and a solid flange, this component ensures maximum concentricity and a secure clamp fit, effectively reducing vibration and preventing shaft marring. The 1-5/8 inch finished bore features a standard 3/8 x 3/16 inch keyseat, enabling a robust key-to-key drive that transmits power through both the shaft and the driven component. Constructed from high-strength sintered steel or ductile iron, it utilizes a 3/4" per foot taper to provide a reliable mechanical lock. This B-series bushing is commonly used to mount B5V sheaves, pulleys, and sprockets onto blower motors and fan shafts. With a 3-11/16 inch outside diameter and a 192 in-lb torque rating, it is the professional choice for maintaining drive alignment in demanding applications.

• Concentric Alignment: The double-split barrel design provides a uniform grip around the shaft, minimizing runout and extending bearing life.
• Enhanced Torque Capacity: Features a key-to-key drive system that prevents slippage under heavy startup loads.
• Easy Installation: The tapered locking system allows for straightforward mounting and removal using three 5/16 x 1-1/4 inch cap screws.
• Durable Construction: Manufactured from ductile iron or steel to withstand the rigors of continuous HVAC operation.
• Versatile Compatibility: Engineered specifically for B-series sheaves and industrial pulleys with a 3-1/8 inch bolt circle.

• What is the torque specification for the mounting bolts? The recommended wrench torque for the 5/16 inch cap screws is 192 in-lbs to ensure a secure fit without over-stressing the flange.
• Will this bushing fit any brand of sheave? This is a B-series split taper bushing designed to be interchangeable with Browning and other manufacturers who utilize the standard B-type split taper specification.
• Does it require a special key? It utilizes a standard 3/8" x 3/16" keyway; always verify your shaft has a matching keyseat before installation.
