Browning 3694858 Split Taper Bushing Type B 1.75 in Bore

Product Description

The BROWNING 3694858 is a Type B split taper bushing designed for use in mechanical power transmission systems. It features a 1.75-inch bore with a 3/8-inch keyway width and 3/16-inch keyway depth, allowing positive shaft engagement with minimal slippage. The outside diameter measures 3.6875 inches, and the bushing is rated to a maximum torque of 192 inch-pounds. Constructed from iron, this bushing delivers reliable performance in industrial drive applications. Installation and removal are handled without special pullers, making it a practical choice for millwrights and mechanical contractors working on sheave and sprocket assemblies.

This bushing is specifically designed for use with B5V sheaves. Typical applications include belt drive systems in HVAC equipment, industrial fans, pumps, and compressors where a positive, concentric fit between the shaft and sheave is required. The split taper design allows the bushing to be tightened evenly around the shaft bore, reducing shaft stress. It is suited for both original equipment installations and maintenance replacement work in light commercial and industrial settings.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Ensure all drive shafts are fully de-energized and locked out before removing or installing this bushing. Clean the shaft, bore, and mating hub surfaces before assembly to ensure proper seating. Tighten mounting fasteners in a cross-pattern sequence to the manufacturer-specified torque value listed on the product documentation.
