Browning 1078427 Type H Split Taper Sprocket Bushing

Product Description

The BROWNING 1078427 is a Type H split taper bushing designed for use with split taper sprockets and sheaves in mechanical power transmission systems. With a 1.5-inch bore diameter and 2.5-inch outside diameter, this iron bushing accepts a 3/8-inch keyway width by 3/16-inch keyway depth to secure the sprocket or sheave to a shaft. It is rated to a maximum torque of 95 inch-pounds. The 1/4 x 3/4 thread size is standard for the H bushing series. Installation is performed by millwrights, maintenance mechanics, and industrial technicians during drive assembly or component replacement.

This bushing is used wherever split taper sprocket and sheave assemblies are specified in industrial and commercial drive systems. The split taper design allows the bushing to be drawn into the sprocket or sheave hub as the fasteners are tightened, creating a concentric, zero-clearance fit on the shaft. Typical applications include conveyor drives, fan drives, and pump drives across light to medium industrial settings.

Key Features

• 1.5-inch bore with 3/8-inch keyway width and 3/16-inch keyway depth
• 2.5-inch outside diameter fits standard H-series sprocket and sheave hubs
• Maximum torque rating of 95 inch-pounds
• Iron construction for durability in industrial drive environments
• 1/4 x 3/4 thread size consistent with H bushing series standards

Compatibility

Designed for use with split taper sprockets and sheaves requiring an H-series bushing with a 1.5-inch bore.

Installation Notes

Installation is typically performed by qualified millwrights or maintenance mechanics. Shut down and lockout/tagout all power to the drive system before beginning any bushing installation or removal work. Use the specified fastener thread size and tighten in a star pattern to ensure even seating of the taper. Do not hammer the bushing into the hub; taper engagement under fastener load is the correct installation method.
