Sprocket for 50 Chain with 1 1/2 in Bore

This finished-bore sprocket fits 50 chain pitch and single-strand drives. It has 28 teeth, a 5.92 in outside diameter and a 5.582 in pitch diameter. The 1 1/2 in bore includes a 3/8 in wide by 3/16 in deep keyway plus two set screws for positive shaft locking.

Limits of 5/8 in Pitch Single-Strand Chain

The 5/8 in pitch and single-strand rating define the torque and speed envelope this sprocket can transmit. Hub projection of .907 in and 3 in hub diameter set the mounting envelope on the shaft. Black-oxide steel construction resists corrosion but does not change the fundamental chain-pairing constraints.

28-Tooth Count Determines Speed Ratio

The 28-tooth count fixes the driven-speed ratio relative to the driving sprocket. Buyers needing a different ratio must select another tooth count; this sprocket cannot be altered. The fixed bore and included keyway also mean it suits only shafts machined to 1 1/2 in with a matching keyseat.

Questions about this item

Should I choose the 28-tooth version or a different tooth count for my 50 chain?

The 28-tooth sprocket gives a 5.582 in pitch diameter and 5.92 in outside diameter; select a different tooth count only if your speed ratio or centre distance requires it.

What does the 5.92 in outside diameter mean once the sprocket is mounted on a 1 1/2 in shaft?

It sets the chain wrap envelope to 5.92 in, so guards and adjacent components must clear that circle; the 1 1/2 in bore with 3/8 in keyway and two set screws locks it to the shaft.

How does the 50 chain pitch limit what this sprocket can transmit?

The 5/8 in pitch (chain number 50) fixes the tooth profile; the steel sprocket with black-oxide finish and 3 in hub handles the load rating for that pitch in single-strand drives.
