60 Chain 12-Tooth Steel Sprocket

This finished-bore sprocket fits 60 series roller chain and carries 12 teeth on a 3.25 in outside diameter. The 1-1/4 in bore includes a 1/4 in keyway cut 1/8 in deep and two set screws for positive shaft locking. It is aimed at maintenance crews replacing worn sprockets on conveyors, agricultural drives or industrial gearboxes.

Black-Oxide Steel Holds Up Under Continuous Running

The carbon-steel body with black-oxide finish resists surface wear when the drive runs hour after hour at full rated speed. Heat-treated teeth maintain pitch accuracy at the 2.898 in pitch diameter, reducing chain stretch and vibration during sustained load cycles. The 2 3/8 in hub and .791 in projection keep the sprocket rigid so alignment stays true over long shifts.

Slide-On Fit With Keyway And Two Set Screws

Installation means sliding the bore onto a 1-1/4 in keyed shaft, engaging the key in the machined slot, then tightening both set screws against the key and shaft flat. The fixed bore cannot be enlarged, so the shaft must match exactly. Misalignment or an undersized key causes premature tooth wear — the most common reason these sprockets come back.

Questions about this item

How much heat does the steel sprocket generate when running continuously?

The steel sprocket itself produces no heat; any warmth comes from chain friction and bearing load in the drivetrain.

What shaft and key stock 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 matching the sprocket bore.

Will this 12-tooth, 60-chain sprocket mesh with my existing 60-chain and tensioner setup?

Yes, it matches 3/4 in pitch single-strand 60 chain and shares the 2.898 in pitch diameter used by standard 60-series tensioners.
