Browning 1078815 Type Q Sprocket Bushing 0.75 in Bore

Product Description

The BROWNING 1078815 is a Type Q split taper sprocket bushing designed for use in power transmission assemblies. It features a 0.75 inch bore with a 0.1875 inch keyway width and a 0.09375 inch keyway depth, allowing secure shaft-to-hub connections under load. The bushing fits sprockets and sheaves with an outside diameter range of 2.766 to 2.875 inches. HVAC and mechanical technicians use this style of bushing to lock belt-drive components onto shafts in fan, blower, and conveyor drive systems. Its split taper design allows quick installation and removal without special tooling in most applications.

This bushing is commonly installed in commercial and industrial drive assemblies where split taper sprockets or sheaves are used. Typical applications include belt-driven blower systems, pump drives, and compressor drive trains found in HVAC and mechanical equipment rooms. The Type Q designation identifies the bushing series, which corresponds to a specific range of sprocket and sheave hub bores. Technicians and millwrights working on scheduled maintenance or component replacement will find this bushing fits into standard Type Q hub configurations.

Compatibility

Designed for use with split taper sprockets and sheaves. Compatible with hubs in the 2.766 to 2.875 inch outside diameter range that accept a Type Q bushing bore configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. Disconnect and lock out all power to the drive system before beginning work, following OSHA lockout/tagout procedures. Clean the shaft, bore, and keyway surfaces before inserting the bushing to ensure proper seating and torque transfer. Do not force the bushing onto the shaft; the split taper design should allow hand-press or light mallet seating before fastener tightening.
