This simplex sprocket with hub is identified by the part number MR-PINON-SIMPLE-1-2-Z57. It has a 1/2" pitch and 57 teeth, and it is machined from SAE 1045 steel. The hub allows direct mounting on a shaft with a keyway, so no separate hub is needed. It is a power transmission component for industrial drives that call for a specific reduction ratio.

The 1/2" pitch matches standard roller chains of that size, while the 57-tooth count sets the transmission ratio when paired with another sprocket on the same chain. The integrated hub adds rigidity to the assembly. EMMAR manufactures this sprocket in SAE 1045 steel, a material known for wear resistance and toughness in continuous service.

You will find this sprocket in chain drives on agricultural machinery, conveyors, lifting equipment and motion systems in industrial plants. It also appears in gearboxes and mechanisms where a defined ratio is required in a compact space. Replacements of worn sprockets and new designs are common uses.

When selecting this sprocket, check the chain pitch (1/2"), the number of teeth (57) and the shaft diameter where it will be mounted. Confirm that the hub bore and keyway fit your shaft; if they do not match, the hub can be machined to size. Proper alignment between sprockets and correct chain tension help avoid premature wear. SAE 1045 steel allows the teeth to be hardened if the application demands greater strength, though that depends on the specific use.
