Browning 1078997 Type Q Sprocket Bushing 1.75 Inch Bore

Product Description

The BROWNING 1078997 is a Type Q split taper bushing designed for use with split taper sprockets and sheaves in power transmission applications. With a 1.75-inch bore, a 0.375-inch keyway width, and a 0.1875-inch keyway depth, this bushing provides a secure, concentric fit when mounting drive components onto shafting. The tapered design allows for easy installation and removal without requiring heat or special presses. Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals install this type of component when servicing belt drive and chain drive assemblies on fan systems, blowers, and related rotating equipment.

This bushing fits split taper sprockets and sheaves with an outside diameter range of 2.766 to 2.875 inches. It is commonly used in commercial and industrial mechanical drive systems where a reliable, precision-bored hub connection is required. The split taper design distributes clamping force evenly around the shaft, reducing the risk of fretting or shaft damage during extended operation. This part is appropriate for HVAC fan drive assemblies, conveyor systems, and other rotating machinery that use standardized split taper components.

Key Features

• Type Q split taper design for secure, concentric shaft-to-hub connection
• 1.75-inch bore accommodates standard shaft sizing
• 0.375-inch keyway width by 0.1875-inch keyway depth for positive torque transfer
• Compatible OD range of 2.766 to 2.875 inches for split taper sprockets and sheaves
• Removable design allows disassembly without shaft or hub damage

Compatibility

Designed for use with split taper sprockets and sheaves in the 2.766 to 2.875 inch outside diameter range. Intended for systems using the standardized Type Q split taper bushing interface.

Installation Notes

Installation should be performed by a qualified mechanical or industrial maintenance technician. De-energize and lock out the drive system before beginning any bushing installation or removal work, following OSHA lockout/tagout procedures. Ensure shaft and bore surfaces are clean and free of burrs before seating the bushing. Do not over-tighten fasteners beyond the fastener manufacturer specifications; consult applicable engineering references for proper assembly sequence.
