Description

A single-row sprocket with a hub, built by EMMAR from SAE 1045 steel. The hub lets you mount it on a shaft and lock it with a key, a set screw, or both, depending on how the drive is set up. It suits low-speed mechanisms and moderate loads where a short ratio and good wear resistance are what matter.
Reading the designation tells you most of what you need. "Simplex" means one row of teeth. The 3/8" figure is the chain pitch the sprocket has to mesh with. Z8 is the tooth count, and that count sets the transmission ratio. SAE 1045 gives the part its strength and hardenability for moderate duty.
You will find this size in agricultural machinery, belt and roller conveyors, light lifting equipment, and general power transmission drives. The compact body and hub fit into tight spaces where you need to reduce speed or reverse rotation. It also works in hand-driven or low-power motorized mechanisms, where pitch accuracy and tooth count decide whether the drive stays in sync.
Before ordering, confirm three things: the chain pitch matches 3/8", the tooth count gives the ratio you want, and the hub bore fits your shaft and fastening method. Align the sprockets, set chain tension to the drive manufacturer's recommendation, and keep the assembly lubricated and clean.
If you need a different pitch, tooth count, or hub style, send the current part number along with a sketch of the main dimensions or a photo of the part and how it sits in the assembly. That is enough for our team to point you to the right equivalent.

Frequently asked questions
- Can this sprocket run with a chain of a different pitch?
- No. Pitch has to match exactly, or you get premature wear, noise, and a risk of the chain jumping. If your chain is another pitch, ask us about the matching version in our sprocket line.
- How do I ask for a special size or more teeth?
- Send your current part number on WhatsApp along with what you need: pitch, tooth count, hub diameter, and fastening type. We review feasibility and quote the option that fits your application.
- What information helps you identify an equivalent?
- The part number you use now, a sketch with the main dimensions, or a photo of the sprocket and the assembly. With that we can confirm compatibility before you order.
