U.s. Tsubaki 40B16F-1C Finished Bore Sprocket 16T 1/2in

Product Description

The U.S. TSUBAKI 40B16F-1C is a finished bore sprocket designed for use with ANSI No. 40 roller chain. It features 16 teeth and a 1/2-inch chain pitch, with a finished bore diameter of 1-3/16 inches and an outside diameter of 2.81 inches. This sprocket is manufactured with a ready-to-install finished bore, eliminating the need for secondary machining before mounting. It is suited for power transmission applications in industrial and mechanical drive systems where accurate chain engagement and reliable torque transfer are required. Licensed mechanics and maintenance technicians are the typical installers.

This sprocket is applicable in light-to-medium duty power transmission drive assemblies using ANSI No. 40 roller chain. Common installation environments include conveyor systems, agricultural equipment, industrial machinery, and general mechanical drives. The finished bore configuration makes it ready for direct shaft mounting without additional boring or machining operations at the job site.

Key Features

• Finished bore design at 1-3/16 inches allows direct shaft installation without secondary machining
• 16-tooth count provides a balanced ratio option for standard drive configurations
• 1/2-inch pitch matches ANSI No. 40 roller chain specifications
• 2.81-inch outside diameter suits compact drive envelope requirements
• ANSI No. 40 chain trade size compatibility for straightforward replacement sourcing

Compatibility

Designed for use with ANSI No. 40 roller chain with a 1/2-inch pitch. Suitable as an OEM-style or replacement finished bore sprocket in standard industrial power transmission drive systems requiring a 16-tooth, No. 40 chain sprocket.

Installation Notes

Installation is typically performed by qualified mechanical or industrial maintenance technicians. Ensure the drive system is fully de-energized and locked out before removing or installing any sprocket. Verify shaft diameter matches the 1-3/16-inch finished bore before mounting, and confirm proper keyway and set screw engagement per the equipment manufacturer's specifications. Chain alignment should be checked after installation to prevent premature wear.
