This simplex sprocket with hub mounts directly on the shaft, eliminating the need for extra bushings and simplifying assembly. It suits equipment that requires a specific transmission ratio with a 3/8" pitch chain.

Manufactured by EMMAR in SAE 1045 steel, this sprocket has a 3/8" pitch and 39 teeth (Z39). The designation Simplex sprocket 3/8" Z39 refers to a single-plate sprocket with a central hub for direct shaft mounting. The 3/8" pitch matches standard chains of that pitch, while the 39-tooth count sets the transmission ratio when paired with another sprocket or gear on the same chain.

Typical uses include chain drives in agricultural machinery, conveyors, packaging equipment, and general motion systems. It is often chosen where moderate speed reduction or multiplication is needed and the mounting space accommodates a sprocket of this diameter. It also serves as a replacement in equipment originally fitted with 3/8" pitch sprockets of a similar tooth count.

When selecting this sprocket, confirm that the chain pitch is 3/8" and that the tooth count suits the desired ratio. The hub can be secured to the shaft by key or set screw, depending on the equipment design. Check alignment between sprocket and gear to prevent premature wear. SAE 1045 steel provides good mechanical strength and is suitable for surface treatments.

For a different tooth count, pitch, or hub configuration, we can manufacture it or find an equivalent.
