Browning 1078955 Type Q Split Taper Sprocket Bushing

Product Description

The BROWNING 1078955 is a Type Q split taper bushing designed for use with split taper sprockets and sheaves in mechanical power transmission systems. It features a 1.5-inch bore with a 3/8-inch keyway width and 3/16-inch keyway depth, and an outside diameter of 4.125 inches. Constructed from iron, this bushing is rated for a maximum torque of 348 inch-pounds. It installs into compatible split taper sprockets and sheaves, providing a secure, concentric shaft connection. Installation and removal are handled by millwrights, maintenance mechanics, and industrial technicians working on conveyor, pump, fan, and general power transmission drive systems.

This bushing suits industrial and commercial drive applications where a reliable, removable shaft-to-hub connection is required. The split taper design allows the bushing to lock onto the shaft with uniform pressure, reducing fretting and shaft wear. It fits split taper sprockets and sheaves across a wide range of industrial equipment including conveyors, blowers, and compressors. The Q series designation indicates this bushing belongs to the Q1 bushing series, with thread size 3/8 x 1-1/4 for the mounting screws.

Installation Notes

Installation is typically performed by qualified millwrights or maintenance mechanics. Disconnect and lock out all power to the drive system before installing or removing the bushing. Clean the bore, shaft, and taper surfaces before assembly, and do not apply lubricant to the taper mating surfaces unless specifically required. Follow the torque sequence recommended for split taper bushings to achieve uniform clamping force.
