U.s. Tsubaki 60B17F-1L Finished Bore Sprocket 17T 3/4in

Product Description

The U.S. TSUBAKI 60B17F-1L is a finished bore sprocket designed for use with ANSI No. 60 roller chain. It carries 17 teeth on a 3/4-inch pitch, with a minimum bore diameter of 1-3/4 inches and an outside diameter of 4.46 inches. Finished bore sprockets arrive ready to mount without additional machining, making them a direct drop-in for replacement or new drive installations. This sprocket is appropriate for light industrial, agricultural, and mechanical power-transmission applications and is typically installed by millwrights, maintenance technicians, or mechanical contractors working on chain-driven equipment.

The 60B17F-1L is suited for applications running ANSI No. 60 roller chain in single-strand configurations. Typical use cases include conveyor drives, pump drives, compressor drives, and general industrial machinery where a 3/4-inch pitch chain and a 17-tooth drive or driven sprocket is specified. The finished bore allows direct shaft mounting with a standard keyway and set-screw arrangement, reducing installation time in field and shop environments alike.

Key Features

• Finished bore construction eliminates post-purchase machining for standard shaft fits
• 17-tooth count provides a defined gear ratio reference point for drive design
• 3/4-inch chain pitch matches ANSI No. 60 roller chain standards
• 4.46-inch outside diameter suits compact drive envelopes
• Minimum bore diameter of 1-3/4 inches accommodates common industrial shaft sizes

Compatibility

Designed for use with ANSI No. 60 single-strand roller chain with a 3/4-inch pitch. Verify shaft diameter and keyway dimensions against bore specifications before installation.

Installation Notes

Installation is typically performed by a millwright or qualified maintenance technician. De-energize and lock out the drive system fully before removing or installing any sprocket. Verify shaft alignment and chain tension after mounting to minimize wear and vibration. Consult applicable ANSI and OSHA machine-guarding requirements before returning the drive to service.
