Its hub allows it to be mounted directly on the shaft with a keyway, without the need for additional hubs. It is machined from SAE 1045 steel, a material that offers good wear resistance and toughness for continuous service. It is a key part in power transmission systems that require specific reduction ratios.

This item is a simplex sprocket with hub with 1/2" pitch and 57 teeth, manufactured by EMMAR in SAE 1045 steel. The full designation is Simplex sprocket 1/2" Z57. The integrated hub facilitates mounting on the shaft and adds rigidity to the assembly. The 1/2" pitch corresponds to standard roller chains of that pitch, and the 57-tooth count defines the transmission ratio when combined with another sprocket on the same chain. It is a power transmission part for industrial service.

Typical applications include chain drives in agricultural machinery, conveyors, lifting equipment and motion systems in industrial plants. It is also used in gearboxes and mechanisms where a specific transmission ratio is needed in a small space. It is commonly found in replacements of worn sprockets or in new designs.

To correctly select this sprocket, take into account the chain pitch (1/2"), the number of teeth (57) and the shaft diameter where it will be mounted. Check that the hub has the appropriate bore and keyway; if they do not match, it can be machined to size. The alignment between sprockets and chain tension are critical to avoid premature wear. SAE 1045 steel allows the teeth to be hardened if greater strength is required, although that is determined by the application.

If you need an equivalent sprocket or a nearby size, the most practical thing is to send us the current part number, a photo of the part or the shaft and chain measurements. We can also evaluate variants in the number of teeth or in the type of hub. Write to us via WhatsApp and we will advise you with no obligation.
