Browning 1122282 Plain Bore Sprocket 14T 1/2 Inch Pitch

Product Description

The BROWNING 1122282 is a minimum plain bore roller chain sprocket designed for use with ANSI 40 chain at a 1/2 inch pitch. Built from steel, it features 14 teeth and accommodates bore diameters from 1/2 inch up to 1-1/8 inches, making it well-suited for custom boring to a finished shaft size. The outside diameter measures 2.49 inches. This sprocket is installed by millwrights, maintenance technicians, and industrial mechanics in power transmission applications where precise chain-and-sprocket alignment is required.

This sprocket is used in light-to-medium duty power transmission assemblies across industrial and commercial equipment. It is appropriate for conveyor drives, packaging machinery, agricultural equipment, and general mechanical drive systems running ANSI 40 roller chain. Because it ships in a minimum plain bore configuration, the end user bores and keys the sprocket to match the specific shaft diameter during installation. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation is typically performed by a millwright or qualified maintenance technician. Before installing or removing the sprocket, de-energize and lock out the drive system per OSHA lockout/tagout procedures. The plain bore must be machined to the correct shaft diameter and keyway before mounting. Ensure proper chain tension and sprocket alignment after installation to prevent premature wear.
