Tritan 15-Tooth Sprocket for 50 Chain

This Tritan sprocket features 15 teeth and a fixed 3/4-inch bore with keyway and set screws. It is designed for single-strand 50 chain with a 5/8-inch pitch. The steel construction includes a black oxide finish for durability. It suits power transmission builds needing this exact chain size.

Capacity and Headroom

The pitch diameter measures 3.006 inches and the outside diameter is 3.32 inches. Hub diameter reaches 2 3/8 inches with a projection of .657 inches. Length through bore is 1 inch. These dimensions define the space it occupies and the load it can transmit. Larger ratios or higher speeds would require a different sprocket.

50 Chain Interface Limits

This sprocket only fits 50 chain size with a 5/8-inch pitch. The bore is fixed at 3/4 inch with a 3/16-inch keyway width and 3/32-inch depth. Two set screws secure the shaft. It cannot adapt to other chain pitches, bore sizes, or multi-strand configurations.

Questions about this item

Will the 15-tooth 50 chain sprocket with a 3/4 in bore and 3/16 in keyway fit the shaft on my existing gearbox?

The fixed bore is exactly 3/4 in with a 3/16 in wide by 3/32 in deep keyway and two set screws; match those dimensions to your shaft and key.

How do I verify the 50BS15H sprocket runs true after mounting it on the 3/4 in shaft?

Tighten both set screws on the key, rotate by hand and check for wobble at the 3.32 in outside diameter; chain should engage all 15 teeth without jumping.

Does the black-oxide finished sprocket come with the two set screws, or must I source them separately?

The box includes the sprocket with 1 in length through bore, 2 3/8 in hub diameter and both set screws already supplied.
