Browning 1078849 Type Q Split Taper Bushing 7/8 in Bore

Product Description

The BROWNING 1078849 is a Type Q split taper bushing designed to mount sprockets and sheaves onto shafts in power transmission systems. It features a 0.875 inch (7/8 inch) bore with a 3/16 inch keyway width and 3/32 inch keyway depth, and a 4.125 inch outside diameter. Constructed from iron, it delivers reliable clamping force when installed with split taper sprockets or sheaves. The bushing accepts a 3/8 x 1-1/4 thread size and is rated for a maximum torque of 348 inch-pounds. This component is installed by mechanical, industrial, and HVAC-adjacent technicians working on belt-and-sheave or chain-driven equipment where precise shaft-to-hub connections are required.

The BROWNING 1078849 belongs to the Q1 bushing series and is suited for use in commercial and industrial power transmission applications. It is used wherever split taper sprockets or sheaves must be secured to a shaft with a keyway. Typical install scenarios include fan drive assemblies, conveyor systems, pump drives, and other rotating equipment requiring a secure, removable hub connection. The split taper design allows for easy installation and removal without damaging the shaft or hub bore.

Compatibility

Designed for use with split taper sprockets and sheaves as noted in product specifications. Fits applications requiring a Q1 series split taper bushing with a 7/8 inch bore.

Installation Notes

Installation and removal should be performed by a qualified mechanical technician familiar with power transmission components. Disconnect and lock out all power sources before servicing any rotating equipment. Use the specified thread size fasteners and tighten in an alternating pattern to ensure even seating of the split taper. Do not use impact tools to drive the bushing into the hub, as this can damage the taper bore or hub.
