Product identity

The Tritan 50BS30H is a 30-tooth steel sprocket finished with black oxide and supplied with a fixed 1 1/4 inch bore, keyway and two set screws. It is intended for maintenance engineers and hobbyists who need a direct replacement on single-strand 50 chain drives.

Installation checks

Verify that your shaft measures exactly 1 1/4 inches and that the keyway dimensions of 1/4 inch width by 1/8 inch depth match the machine key. Confirm the chain pitch is 5/8 inch and that the 6.32 inch outside diameter clears adjacent guards or structure.

Thermals noise and power

In normal operation the steel body runs at ambient temperature with no active cooling and produces only the mechanical noise of chain engagement. Power draw is determined entirely by the driven load and the drivetrain efficiency, not by the sprocket itself.

Questions about this item

Does the sprocket come with the set screws already in the box?

Yes, the package includes two set screws along with the finished-bore sprocket.

How do I decide between different bore sizes for this 30-tooth model?

This unit has a fixed 1 1/4 inch bore with a 1/4 inch wide by 1/8 inch deep keyway; other bore sizes would be a different part number.

Will the 6.32 inch outside diameter clear my existing chain guard?

The sprocket measures 6.32 inches across the teeth, so compare that dimension directly to your guard’s inner clearance.
