Precision Power Transmission Sprocket

The Tritan 40BS23H is a finished-bore sprocket engineered for 40 chain size systems requiring exact pitch engagement. Its 23-tooth configuration delivers precise rotational control for industrial and agricultural drive applications. The 1in bore with integrated keyway ensures secure shaft mounting without slippage under load.

Sustained Load Performance

Under continuous operation the steel construction resists elongation and tooth deformation across extended duty cycles. Black oxide finish reduces surface wear where chain rollers engage the 3.672in pitch diameter. Two set screws lock the hub firmly against axial drift when vibration persists over long runs.

Thermal and Mechanical Stability

Steel body dissipates frictional heat evenly across the 3.94in outside diameter during normal power transfer. The 1in length through bore distributes radial forces across the full hub width of 3in. Fixed bore type eliminates backlash that can accelerate wear in high-cycle environments.

Questions about this item

Does the 3.94 in outside diameter sprocket generate noticeable heat or noise when running continuously?

The steel sprocket itself has no motor or bearings, so it produces no heat or noise; any sound or temperature rise comes from the chain and driver, not the 23-tooth wheel.

What shaft and key stock must I already have to mount this 1 in bore sprocket with its 1/4 in keyway?

You need a 1 in diameter shaft and a 1/4 in wide by 1/8 in deep key that matches the fixed bore and keyway dimensions.

Will this 40 chain pitch sprocket mesh with an older #40 roller chain I already own?

Yes, the 1/2 in pitch and 23 teeth match standard #40 chain, so it will engage correctly with existing #40 chain of the same pitch.
