Browning 1129246 Finished Bore Sprocket 14T 3/4in Pitch

Product Description

The BROWNING 1129246 is a finished bore roller chain sprocket designed for use with ANSI No. 60 roller chain. It features 14 teeth and a 3/4 inch chain pitch, with a maximum bore diameter of 1-7/16 inches and a hub diameter of 2.578 inches. The outside diameter measures 3.74 inches. Constructed from steel, this sprocket is built to handle the load and wear demands typical of industrial power transmission applications. Installation is straightforward for maintenance technicians and millwrights working on conveyor systems, HVAC drive trains, and general machinery.

This sprocket suits a wide range of industrial and commercial power transmission applications where ANSI No. 60 roller chain is used. Typical installations include conveyor drives, fan drives, pump drives, and other mechanical systems requiring a reliable finished bore sprocket. The finished bore configuration means the bore is machined to a fixed diameter at 1-7/16 inches, ready for direct shaft mounting without additional machining.

Key Features

• Finished bore at 1-7/16 inches for direct shaft installation
• 14-tooth count with 3/4 inch pitch for ANSI No. 60 roller chain
• Steel construction for durability in demanding drive applications
• 3.74 inch outside diameter with 2.578 inch hub diameter
• ANSI/UNSPSC classified for standard procurement and sourcing

Compatibility

Designed for use with ANSI No. 60 roller chain with a 3/4 inch pitch. The fixed finished bore of 1-7/16 inches is suited for shafts machined to that diameter.

Installation Notes

Installation is typically performed by a millwright or qualified maintenance technician. De-energize and lock out the drive system before beginning any sprocket replacement. Ensure the shaft diameter matches the finished bore of 1-7/16 inches before mounting. Align the sprocket and mating sprocket carefully to minimize chain wear and lateral load on bearings.
