Browning 1078534 Type H Split Taper Sprocket Bushing

Product Description

The BROWNING 1078534 is a Type H split taper bushing designed for use with split taper sprockets and sheaves in power transmission drive systems. It features a 24mm bore with an 8mm keyway width and 3.5mm keyway depth, providing a secure, concentric fit on shafting. The outside diameter measures 2.5 inches. Constructed from iron, this bushing delivers the rigidity and wear resistance required in industrial drive applications. A 1/4 x 3/4 thread size is used for the taper locking screws, and the bushing is rated for a maximum torque of 95 inch-pounds. Licensed HVAC and mechanical contractors, millwrights, and industrial maintenance technicians typically install this component during drive assembly or rebuild work.

This bushing is suited for light-duty industrial and commercial power transmission applications where a split taper mounting solution is required. It is compatible with split taper sprockets and sheaves across a range of industries including HVAC fan drives, conveyor systems, and pump drives. The split taper design allows for straightforward installation and removal without damage to the shaft or hub, making it practical for applications requiring periodic disassembly or service.

Compatibility

Designed for use with split taper sprockets and sheaves requiring a Type H bushing with a 24mm bore.

Installation Notes

Installation and removal should be performed by a qualified millwright or mechanical technician following lockout/tagout procedures before working on any drive system. Clean the bore, shaft, and keyway surfaces before assembly to ensure proper seating of the taper. Apply fastener torque evenly and incrementally in a cross pattern to draw the bushing uniformly into the hub. Do not use impact tools on the locking screws, as this can crack the bushing or damage the hub bore.
