30-tooth steel sprocket for 40 chain

This 30-tooth steel sprocket fits 40 chain with a 1/2 inch pitch. It has a plain bore of 5/8 inch and a hub on one side. The black oxide finish protects the steel surface. It is supplied new for power-transmission assemblies.

Sustained load behaviour

The steel body and black oxide coating resist wear during continuous rotation. A hub diameter of 3 1/4 inch and projection of .716 inch distribute torque evenly across the teeth. No keyway or set screws are present, so retention relies on a press fit or external locking device.

Pre-order checks

Verify that your shaft measures exactly 5/8 inch and suits a plain bore without keyway. Confirm the chain is single-strand 40 size with 1/2 inch pitch. Ensure the 5.06 inch outside diameter and 4.783 inch pitch diameter clear adjacent components. Buyers needing a keyway or a different bore size cannot use this sprocket.

Questions about this item

Does the 5.06 in outside diameter on this 30-tooth sprocket leave enough clearance inside my existing #40 chain guard?

The sprocket measures 5.06 in outside diameter and 4.783 in pitch diameter, so compare those dimensions with the guard's internal space before fitting.

What shaft size and keyway style do I need to mount this plain-bore sprocket?

The bore is 5/8 in plain with no keyway; you must supply a 5/8 in shaft and either drill a keyway or use a set-screw collar for retention.

Will the 1 in length through bore and .716 in hub projection fit the spacing on my older #40 drive?

Hub projection is .716 in and length through bore is 1 in; verify those measurements against your existing hub spacing and sprocket alignment.
