This simplex sprocket with hub is identified by part number MR-PINON-SIMPLE-3-8-Z15. It mounts directly on a shaft with keyway, so no extra adapter is needed. The design suits drives that require a fixed and precise transmission ratio.

The sprocket belongs to the 3/8" pitch series and has 15 teeth. It is made of SAE 1045 steel, a medium-carbon grade known for good mechanical strength and hardenability in power transmission uses. The simplex configuration means a single row of teeth, while the hub is the central section that carries the bore and keyway for shaft mounting.

Typical applications include chain drives in agricultural equipment, conveyors, packaging lines, lifting systems, and other machinery where a constant speed ratio is needed. The combination of 3/8" pitch and 15 teeth makes it common in moderate-speed, medium-load mechanisms. It also serves as a replacement part when a sprocket wears out or when the ratio must be changed.

When selecting this sprocket, check three things: chain pitch (3/8"), number of teeth (15), and shaft diameter. The hub bore and keyway must match the shaft; if they do not, a bushing or adapter can be machined, but that is the user's responsibility. Also confirm alignment with the driven sprocket and correct chain tension. Install with the chain properly lubricated and avoid overtightening to prevent premature wear.

For an equivalent sprocket, send the exact part number or the full designation, such as Simplex sprocket 3/8" Z15. From that we can identify alternatives in the same series or with different tooth counts, as long as pitch and hub type are compatible. We can also help with the transmission ratio if you provide your machine data.
