Browning 1078971 Type Q Split Taper Bushing 1.625 in Bore

Product Description

The BROWNING 1078971 is a Type Q split taper bushing designed for use with split taper sprockets and sheaves in power transmission applications. Machined from iron, this bushing features a 1.625-inch bore with a 3/8-inch keyway width and 3/16-inch keyway depth, providing a secure, keyed connection to the shaft. The split taper design allows for easy installation and removal without damaging the sprocket or sheave hub. With a maximum torque rating of 348 inch-pounds and a 4.125-inch outside diameter, it is built for demanding mechanical drive systems found in industrial and commercial settings. Licensed technicians and millwrights install this component as part of belt and chain drive assemblies.

This bushing is suited for use in industrial power transmission systems where split taper sprockets and sheaves are employed. Typical applications include conveyor drives, HVAC fan drives, pump drives, and other belt or chain drive configurations requiring a reliable, removable shaft-to-hub connection. The Q series bushing fits into compatible split taper hubs and is commonly specified in both new installations and replacement service work across light to medium industrial machinery.

Compatibility

Designed for use with split taper sprockets and sheaves that accept the Type Q bushing series. Verify hub bore and bushing series designation before installation to confirm fitment.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with power transmission components. Disconnect and lock out all power to the drive system before beginning work. Clean the bushing bore, shaft, and hub tapers thoroughly before assembly, and ensure the keyway and key are properly aligned before tightening the bushing screws. Do not force the bushing into the hub using impact tools, as this can damage the taper fit and compromise holding power.
