Browning 1880053 Finished Bore Sprocket 23T 1/2in Pitch

Product Description

The BROWNING 1880053 is a finished bore roller chain sprocket designed for use with standard 40-series chain. It features 23 teeth, a 1/2 inch chain pitch, and a 7/8 inch finished bore diameter, giving it an outside diameter of 3.94 inches. Constructed from steel, this sprocket is suited for power transmission applications where a pre-machined bore is required, eliminating the need for additional boring or machining before installation. It is typically installed by millwrights, maintenance mechanics, and industrial technicians on conveyor systems, drive assemblies, and general power transmission equipment.

This sprocket is intended for use with ANSI 40-series roller chain in industrial and commercial drive systems. It fits applications that require a direct-mount finished bore component without secondary machining. The 23-tooth count and 1/2 inch pitch make it a common selection for moderate-speed, moderate-load conveyor and drive configurations found in manufacturing, material handling, and agricultural equipment.

Key Features

• Finished bore design at 7/8 inch eliminates the need for additional machining prior to installation
• 23 teeth with 1/2 inch pitch for compatibility with ANSI 40-series roller chain
• 3.94 inch outside diameter suits compact drive assemblies
• Steel construction provides durability in demanding industrial environments
• Single-piece design for straightforward shaft mounting

Compatibility

Designed for use with ANSI 40-series roller chain with a 1/2 inch chain pitch. Intended as a direct-replacement or new-installation finished bore sprocket for industrial and commercial power transmission drive systems.

Installation Notes

Installation is typically performed by qualified millwrights or maintenance mechanics. Shut down and lock out the drive system completely before removing or installing any sprocket. Ensure the shaft diameter matches the 7/8 inch finished bore before mounting, and verify sprocket alignment with a straightedge or laser alignment tool to prevent premature chain and sprocket wear. Secure with appropriate set screws or keyway hardware as required by the shaft configuration.
