The simplex sprocket 3/8" Z9 is a chain drive sprocket with an integrated hub and 9 teeth. It is used to drive 3/8" pitch chains in equipment where space is limited and a short transmission ratio is needed. Its hub allows it to be mounted directly on a keyed shaft, without the need for adapters.

This sprocket has a 3/8" pitch, 9 teeth (z=9) and is manufactured in SAE 1045 steel. The designation Simplex Sprocket 3/8" Z9 indicates that it is single-strand, with a hub, and that its number of teeth is 9. The 3/8" pitch corresponds to chains of that pitch, very common in light and medium-duty drives. The hub gives it the body to mount on the shaft and allows it to be secured with a set screw or key depending on the equipment design.

It is used in chain drives for agricultural machinery, conveyors, mixers, elevators and power transmission equipment in general. It also appears in factory implements and in mechanisms where a reduction or multiplication with few teeth is required. Because it is 3/8" pitch, it is common in motion lines where compactness matters more than transmitting high power.

To select it, verify that the chain pitch matches 3/8" and that the number of teeth is suitable for the desired ratio. Check the shaft diameter and the type of hub fastening. During installation, align the sprocket with the driven wheel and check the chain tension. Proper lubrication and correct alignment extend the life of the assembly.
