Tritan 50BS10H 10-tooth sprocket for 50 chain

The Tritan 50BS10H is a finished-bore sprocket with a 7/8 inch bore, keyway and set screws included. It is designed for single-strand 50 chain drives in power-transmission applications. The steel body carries a black-oxide finish for corrosion resistance. Collectors of industrial hardware will also appreciate the original packaging and branding.

Thermals noise and power draw in normal use

As a passive steel component the sprocket generates no noise, vibration or heat of its own. It adds negligible rotating mass to the shaft and imposes no electrical load on the system. Operating temperature and sound levels are determined entirely by the driven machinery and lubrication regime.

The specification that decides fit

The critical dimension is the 7/8 inch fixed bore with a 3/16 inch keyway width and 3/32 inch depth, matched to a 10-tooth, 2.023 inch pitch diameter profile for 5/8 inch pitch chain. Buyers needing a different bore size, tooth count or chain pitch cannot use this part.

Questions about this item

How do I install the Tritan 50BS10H sprocket and align the 3/16 in keyway correctly?

Slide the sprocket onto the 7/8 in shaft, engage the 3/16 in wide by 3/32 in deep keyway with the shaft key, then tighten both included set screws against the key and shaft flat to prevent rotation.

What maintenance will the black-oxide steel sprocket need over time?

Inspect the 10 teeth for hooking or uneven wear, check the 1 9/16 in hub and 1 in bore length for looseness, and re-tighten the two set screws if vibration develops; replace when tooth profile no longer matches 50 chain pitch.

At what point does the 2.023 in pitch diameter limit power transmission under sustained load?

The 2.023 in pitch diameter on a 10-tooth sprocket creates high tooth loading and chordal action, so chain tension fatigue and accelerated tooth wear become the limiting factors before hub or bore strength is reached.
