This item is a simplex sprocket with hub, manufactured by EMMAR in SAE 1045 steel, with 3/8" pitch and 39 teeth (Z39). The designation Simplex sprocket 3/8" Z39 indicates that it is a single-plate sprocket with a central hub for direct mounting on a shaft. The 3/8" pitch corresponds to standard chains of that pitch, and the 39-tooth count defines the transmission ratio when combined with another sprocket or gear of the same chain.

It is used in chain drives in agricultural machinery, conveyors, packaging equipment and motion systems in general. It is common in applications where moderate reduction or multiplication is needed and the mounting space allows a sprocket of this diameter. It is also used as a replacement component in equipment that originally comes with 3/8" pitch sprockets with a similar number of teeth.

To correctly select this sprocket, verify that the chain pitch matches 3/8" and that the number of teeth is compatible with the desired transmission ratio. The hub allows the sprocket to be secured to the shaft by key or set screw, depending on the equipment design. It is important to check the alignment between sprocket and gear to avoid premature wear. SAE 1045 steel offers good mechanical resistance and suitability for surface treatments.
