U.s. Tsubaki 35B18FL Finished Bore Sprocket 18T 3/8in

Product Description

The U.S. TSUBAKI 35B18FL is a finished bore sprocket designed for use with ANSI No. 35 roller chain. It carries 18 teeth on a 3/8-inch pitch and features a fixed 3/4-inch bore diameter, making it a ready-to-install component that requires no additional machining. The sprocket body is manufactured from steel, providing the durability needed in industrial and mechanical power-transmission applications. With an outside diameter of 2.35 inches and a hub diameter of 1.719 inches, this sprocket suits compact drive configurations. It is installed by mechanical technicians and maintenance professionals working on conveyor systems, small machinery, and light industrial equipment.

This sprocket is suited for light-duty to medium-duty roller chain drive systems using ANSI No. 35 chain with a 3/8-inch pitch. Typical applications include conveyor assemblies, packaging equipment, agricultural machinery, and general mechanical drives where a pre-finished bore eliminates the need for secondary machining operations. The fixed 3/4-inch bore is both the minimum and maximum bore diameter for this sprocket, so shaft sizing must match exactly before installation.

Key Features

• Finished bore at 3/4 inch - no machining required before installation
• 18 teeth with 3/8-inch pitch for use with ANSI No. 35 roller chain
• Steel construction for durability in industrial power-transmission applications
• Outside diameter of 2.35 inches suits compact drive configurations
• Hub diameter of 1.719 inches for positive shaft engagement
• Single-piece ready-to-mount design reduces installation time

Compatibility

Designed for use with ANSI No. 35 roller chain at 3/8-inch pitch. The bore diameter is fixed at 3/4 inch; verify shaft diameter prior to ordering.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians. De-energize all drive equipment and lock out the power source before mounting or removing sprockets. Verify shaft diameter matches the 3/4-inch bore before pressing or keying the sprocket onto the shaft. Ensure proper chain tension and sprocket alignment after installation to prevent premature wear.
