Browning 1134600 Finished Bore Sprocket 45T 1/2in Pitch

Product Description

The BROWNING 1134600 is a finished bore roller chain sprocket designed for use with standard No. 40 chain on a 1/2 inch pitch. Machined from steel, this 45-tooth sprocket arrives ready to install with a 1 inch finished bore — no secondary boring or reaming required. The 3.5 inch hub diameter and 7.45 inch outside diameter are sized for typical industrial and mechanical drive applications. It is installed by mechanical contractors, maintenance technicians, and drive system specialists working on conveyor, pump, and general power-transmission equipment.

This sprocket suits light-to-medium duty roller chain drive systems that use No. 40 chain. Common install scenarios include conveyor drives, auger assemblies, pump drive trains, and other equipment requiring a precise finished bore with no additional machine work. The fixed 1 inch minimum and maximum bore diameter means this sprocket is specifically suited to 1 inch shafts and is not intended for re-boring to alternate shaft sizes.

Key Features

• Finished bore at exactly 1 inch — installs directly onto a 1 inch shaft without additional machining
• 45 teeth on 1/2 inch pitch for use with standard No. 40 roller chain
• Steel construction for durability in industrial drive applications
• 7.45 inch outside diameter with 3.5 inch hub diameter for balanced load distribution
• Sold as a single unit with no minimum order requirement beyond one piece

Compatibility

Designed for use with ANSI No. 40 roller chain on a 1/2 inch pitch. Fits 1 inch diameter shafts only. Suitable as an OEM-style replacement or new-installation sprocket in any drive system specifying a 45-tooth, No. 40 finished bore sprocket.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance mechanic. Disengage and lock out all power to the drive system before mounting or removing sprockets. Verify shaft diameter matches the 1 inch finished bore before installation, and ensure proper chain alignment and tension after assembly per the equipment manufacturer's drive specifications. Follow applicable ANSI and OSHA machine-guarding requirements for exposed roller chain drives.
