U.s. Tsubaki 40P23 Split Taper Sprocket 23 Teeth

Product Description

The U.S. TSUBAKI 40P23 is a split taper sprocket designed for No. 40 roller chain applications with a 1/2 inch chain pitch. Featuring 23 teeth and a P-series bushing bore, this sprocket accommodates a taper-lock style bushing that allows for straightforward shaft mounting and removal without disturbing surrounding components. The outside diameter measures 3.94 inches. It is suited for mechanical power transmission systems found in industrial, agricultural, and manufacturing environments. Installation and adjustment are handled by maintenance mechanics and industrial technicians.

This sprocket is used in drive systems that rely on No. 40 roller chain, the most common standard single-strand roller chain pitch class in North American industrial equipment. Split taper designs are common in conveyor drives, pump drives, packaging machinery, and material handling equipment where shaft removal must remain quick and accessible. The P-series bushing bore accepts a standard taper-lock bushing, which must be sourced separately to match the desired shaft diameter.

Key Features

• Split taper design allows bushing installation and removal without full shaft disassembly
• P-series bushing bore accepts standard taper-lock bushings for a range of shaft sizes
• 23-tooth count provides moderate speed reduction ratios in paired drive configurations
• Engineered for No. 40 roller chain with 1/2 inch pitch per ANSI standards
• 3.94 inch outside diameter suits compact drive configurations

Compatibility

Designed as an OEM-style replacement or new-installation sprocket for No. 40 roller chain drive systems using P-series taper-lock bushings. Bushing is sold separately and must match the target shaft diameter.

Installation Notes

Installation is typically performed by qualified industrial maintenance technicians familiar with mechanical power transmission components. Disconnect and lock out all power to the drive system before mounting or removing the sprocket. A matching P-series taper-lock bushing of the correct shaft bore size is required and must be installed per the bushing manufacturer torque and seating specifications. Verify sprocket alignment with a straightedge across both sprocket faces before returning the drive to service.
