Browning 1883438 Finished Bore Sprocket 30T 3/4 in Pitch

Product Description

The BROWNING 1883438 is a finished bore roller chain sprocket designed for use with No. 60 chain at a 3/4 inch pitch. It carries 30 teeth, a 1 inch bore diameter, and a 4.016 inch hub diameter, with an outside diameter of 7.59 inches. Machined from steel, this sprocket arrives ready to install without additional boring or machining. It is a standard component in mechanical power transmission applications, typically installed by industrial maintenance technicians and mechanical contractors working on conveyor systems, drive trains, and similar chain-driven equipment.

This sprocket is suited for light to medium-duty power transmission setups that use ANSI No. 60 roller chain. Its finished bore construction makes it appropriate for direct shaft mounting in applications where the bore size matches the shaft exactly. Common installation scenarios include conveyor drives, agricultural equipment drives, and general industrial machinery where a 3/4 inch pitch chain is specified. The steel construction provides durability in demanding operating environments.

Key Features

• Finished bore design — no additional machining required before installation
• 30 teeth with 3/4 inch chain pitch, compatible with ANSI No. 60 roller chain
• Steel construction for strength and wear resistance in industrial environments
• 1 inch bore diameter for direct shaft mounting
• 7.59 inch outside diameter and 4.016 inch hub diameter for standard drive configurations

Compatibility

Designed for use with ANSI No. 60 roller chain at 3/4 inch pitch. Bore diameter is fixed at 1 inch; verify shaft diameter before ordering.

Installation Notes

Installation is typically performed by qualified mechanical or industrial maintenance technicians. De-energize and lock out the drive system before mounting or removing sprockets in accordance with applicable OSHA lockout/tagout procedures. Ensure the shaft is clean and free of burrs before pressing the sprocket into position. Align the sprocket face squarely with mating sprockets to prevent premature chain and tooth wear.
