Tritan 50BS12H 12T 50 Chain Sprocket 1in Bore Keyway Black Oxide

Precision power-transmission component

The Tritan 50BS12H sprocket is a finished-bore steel component built for single-strand 50 chain. Its 12-tooth profile and 1-inch bore with a 1/4-inch keyway suit machinery that demands accurate timing and torque transfer.

Keyway and set-screw retention

A 1/8-inch deep keyway mates with a standard key to prevent rotational slip, while two included set screws lock the hub axially on the shaft. The black-oxide finish adds corrosion resistance without altering critical dimensions.

12-tooth capacity and limits

The 2.415-inch pitch diameter and 2.71-inch outside diameter handle moderate loads on 5/8-inch pitch chain. Twelve teeth limit wrap angle, so high-speed or shock-load drives will need a larger sprocket to maintain chain engagement.
