Browning 1078898 Type Q Sprocket Bushing 1.1875 in Bore

Product Description

The BROWNING 1078898 is a Type Q split taper bushing designed for use with split taper sprockets and sheaves in power transmission applications. It features a 1.1875-inch bore with a 0.25-inch keyway width and 0.125-inch keyway depth, providing a secure, precision fit on drive shafts. The bushing accommodates an outer diameter range of 2.766 to 2.875 inches and is engineered to deliver consistent clamping force when installed in compatible split taper components. Mechanical contractors, industrial maintenance technicians, and millwrights install this type of bushing in conveyor systems, pump drives, compressor drives, and general industrial power transmission assemblies.

This bushing is suited for use in both light and moderate-duty industrial drive systems where split taper mounting hardware is specified. The Type Q designation corresponds to a standardized taper series, making it a direct-fit component in a wide range of split taper sprocket and sheave configurations. It is commonly found in fixed-plant conveyor lines, blower drives, and pump stations where reliable shaft-to-hub engagement is required.

Key Features

• 1.1875-inch bore for precise shaft fit
• Keyway dimensions of 0.25-inch width by 0.125-inch depth for keyed shaft engagement
• Compatible OD range of 2.766 to 2.875 inches
• Type Q split taper design allows installation and removal without disturbing adjacent components
• Standardized taper series for broad fitment across split taper sprockets and sheaves

Compatibility

Designed for use with split taper sprockets and sheaves that accept a Type Q bushing with a 1.1875-inch bore.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disengage and lock out all power to the drive system before mounting or removing the bushing. Ensure the shaft, bore, and keyway surfaces are clean and free of burrs before assembly. Follow the sprocket or sheave manufacturer torque sequence for the mounting capscrews to achieve uniform clamping force.
