New Steel Sprocket for Chain Drives

This 19-tooth steel sprocket is finished with a 1 1/4 in bore, keyway and set screws so it mounts directly on a shaft without additional machining. It suits maintenance teams and machinery builders who need a ready-to-install component for 50 chain size drives.

Fits Single-Strand 5/8 in Pitch Systems

The sprocket accepts single-strand 5/8 in pitch chain and its one-side hub design leaves the opposite face clear for guards or bearings. Black-oxide finish resists corrosion while the fixed bore and included set screws lock the unit in place without a separate locking device.

Consistent Engagement Under Continuous Operation

Hardened steel teeth and a 3.797 in pitch diameter maintain accurate chain engagement during sustained load cycles. The 4.12 in outside diameter and 3 in hub provide stable rotational mass, while the 1/4 in keyway width and 1/8 in depth transmit torque without backlash when the drive runs continuously.

Questions about this item

How much power does the 19-tooth steel sprocket transmit at continuous speed?

Power capacity depends on the chain tension and shaft speed in your drive; the sprocket itself is a passive 50-chain steel component with a 3.797 in pitch diameter and 1 in length through bore.

What noise or heat does the sprocket generate when running all day?

The sprocket has no moving parts of its own; any noise or heat comes from the chain mesh and bearing supports in your assembly, not from the 4.12 in outside-diameter steel hub.

Which shaft and keyway must I already have to mount this sprocket?

A 1 1/4 in diameter shaft with a 1/4 in wide by 1/8 in deep keyway matches the fixed bore and included set screws.
