U.s. Tsubaki 40B13FL Finished Bore Sprocket 13T 1/2in

Product Description

The U.S. TSUBAKI 40B13FL is a finished bore sprocket designed for use with ANSI No. 40 roller chain. It features 13 teeth and a 1/2 inch chain pitch, with a maximum bore diameter of 3/4 inch and an outside diameter of 2.33 inches. Constructed from steel, this sprocket is machined to a finished bore, meaning the bore is ready for direct shaft installation without additional machining. It is sized for light-to-medium duty power transmission applications and is installed by mechanical technicians and millwrights in conveyor, drive, and general machine applications.

This sprocket is suited for use in industrial and commercial power transmission systems where ANSI No. 40 roller chain is the selected drive chain. Typical applications include conveyor systems, packaging equipment, agricultural machinery, and general-purpose mechanical drives. The finished bore design makes it appropriate for installations where the shaft diameter matches the 3/4 inch maximum bore specification.

Compatibility

Designed for use with ANSI No. 40 roller chain at 1/2 inch pitch. Intended for shafts up to 3/4 inch in diameter. Verify shaft diameter, keyway requirements, and chain trade size before installation.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights. Disengage and lock out all power to the drive system before removing or installing any sprocket. Confirm shaft diameter does not exceed the 3/4 inch maximum bore before mounting. After installation, verify chain alignment and tension per the chain manufacturer's specifications before returning the system to service.
