3307 Series 8mm Pitch Steel Set-Screw Sprocket (8mm REX™ Bore, 14 Tooth)

The 8mm REX™ bore of this 14 Tooth sprocket enables awesome positive drive on 8mm REX shafting–such as that of our 5203 or 5204 Series Yellow Jacket Planetary Gear Motors.

Importantly, its 8mm long protrusion matches the thickness of standard Sonic Hubs. This makes exact alignment a breeze when it’s paired with a larger sprocket mounted to a Sonic Hub!

Its steel construction also excellently resists wear, tear, and corrosion.
