This single-strand sprocket with hub runs on 3/8" pitch chain and carries 9 teeth. It suits compact drives that need a short ratio, and the hub lets you mount it straight onto a keyed shaft without adapters.

The sprocket is made of SAE 1045 steel. Its code, Simplex sprocket 3/8" Z9, tells you it is single-strand, has a hub, and counts 9 teeth (z=9). The 3/8" pitch matches chain of that size, which is common in light and medium drives. The hub provides enough body to sit on the shaft and to be locked with a screw or key, depending on how the equipment is built.

You will find this sprocket on agricultural machinery, conveyors, mixers, elevators and general power transmission equipment. It also shows up on shop-built implements and in mechanisms that call for a small reduction or step-up. Because the pitch is 3/8", it tends to appear in motion lines where compactness matters more than moving high power.

When choosing one, confirm the chain pitch is 3/8" and that 9 teeth give you the ratio you want. Check the shaft diameter and how the hub will be fastened. At assembly, line the sprocket up with the driven wheel and set the chain tension. Lubrication and alignment both affect how long the drive lasts.
