Browning 3694742 Split Taper Bushing 7/8 Inch Bore

Product Description

The BROWNING 3694742 is a Type B split taper bushing designed for mounting sheaves and sprockets on drive shafts in industrial power transmission systems. With a 7/8-inch bore and 3/16-inch keyway width by 3/32-inch keyway depth, this bushing provides a secure, concentric fit on the shaft. Constructed from iron, it delivers the rigidity and wear resistance required in continuous-duty applications. The split taper design allows installation and removal without special tooling, reducing downtime during maintenance. Licensed mechanics and millwrights working on belt drive systems will find this bushing straightforward to install and re-torque to specification.

This bushing is intended for use with B5V sheaves in v-belt drive configurations. It is suited for residential and light commercial HVAC blower assemblies, industrial fans, pumps, and conveyor drives where a standard Type B split taper mount is specified. The outside diameter measures 3.6875 inches, and the bushing accepts a 5/16 x 1-1/4 thread size for the mounting screws. Maximum rated torque is 192 inch-pounds, making it appropriate for moderate-load shaft connections in single or multi-groove sheave setups.

Key Features

• Split taper design allows tool-free installation and clean removal without damaging the shaft
• 7/8-inch bore with 3/16-inch keyway width and 3/32-inch keyway depth for positive shaft engagement
• Iron construction provides durability and dimensional stability under load
• Maximum torque rating of 192 inch-pounds suits moderate-duty drive applications
• 5/16 x 1-1/4 thread size for mounting screws included in the bushing body
• Outside diameter of 3.6875 inches fits standard Type B sheave bores

Compatibility

Designed for use with B5V sheaves. Verify sheave bore and keyway dimensions before installation to confirm fit.

Installation Notes

Installation should be performed by a qualified mechanic or millwright. Disconnect and lock out all power to the drive system before beginning work. Clean shaft and bushing bore surfaces before seating the bushing to ensure proper taper engagement. Tighten mounting screws evenly in an alternating pattern to the fastener specification for the thread size used, and re-check torque after initial run-in.
