Browning 1078211 Type H Split Taper Sprocket Bushing

Product Description

The BROWNING 1078211 is a Type H split taper bushing designed for use with split taper sprockets and sheaves in industrial drive applications. Machined from iron, this bushing features a 0.5 inch bore with a 1/8 inch keyway width and 1/16 inch keyway depth, allowing secure shaft engagement with a keyed connection. The 1/4 x 3/4 thread size supports the standard split taper clamping method. Rated to a maximum torque of 95 inch-pounds, the 1078211 delivers reliable holding force in light-to-medium duty power transmission setups. Licensed HVAC, mechanical, and industrial service technicians routinely specify this bushing type for chain drive and belt drive systems requiring a removable, adjustable bore-to-shaft fit.

This bushing fits split taper sprockets and sheaves where a Type H bore insert is specified. The 2.5 inch outside diameter and H-series profile make it appropriate for a range of sprocket and sheave hub bores engineered around the split taper standard. Typical install scenarios include conveyor drives, fan drives, pump shafts, and other rotating equipment found in mechanical rooms, HVAC systems, and light industrial settings. Installers working in trade environments select this part when replacing a worn or damaged bushing without replacing the entire sprocket or sheave assembly.

Key Features

• Type H split taper design allows easy installation and removal without damaging the sprocket or sheave hub
• 0.5 inch bore with 1/8 inch keyway width and 1/16 inch keyway depth for keyed shaft connections
• Maximum torque rating of 95 inch-pounds for reliable holding force in power transmission applications
• Iron construction provides strength and durability in typical mechanical room and industrial environments
• 1/4 x 3/4 thread size is consistent with the standard split taper clamping screw specification
• 2.5 inch outside diameter suits a wide range of H-series sprocket and sheave hub bores

Compatibility

Designed for use with split taper sprockets and sheaves requiring a Type H bushing. Consult sprocket or sheave manufacturer documentation to confirm hub bore and bushing series compatibility before ordering.

Installation Notes

Installation is performed by qualified mechanical or millwright technicians. De-energize and lock out the drive system before disassembly or assembly. Clean the bushing bore, keyway, and mating hub surfaces before seating the bushing to ensure proper clamping. Tighten bushing screws evenly and in sequence to the specified torque for the H series; do not use air tools without a torque-limiting device, as overtightening can crack the hub.
