The simplex sprocket 3/4" Z9 is a sprocket that MR Accesorios Industriales sells, designed to transmit motion in 3/4" pitch chains. Its hub allows it to be mounted on shafts and secured with a set screw or key depending on the case. It is used in power transmission equipment where a short transmission ratio and a wear-resistant component are needed. Being made of SAE 1045 steel, it offers good toughness and suitability for machining and subsequent heat treatment if the service requires it.

This item is a simplex sprocket with hub, 3/4" pitch and 9 teeth (z=9), sold by MR in SAE 1045 steel. The designation Simplex Sprocket 3/4" Z9 indicates that it is a single-plate sprocket with a central hub for shaft mounting. The 3/4" pitch defines the compatible chain, and the 9 teeth determine the transmission ratio and the tangential speed. The hub allows the sprocket to be secured to the shaft by means of a set screw, key or both, depending on the equipment design. It is a general-purpose power transmission part in machinery.

Typical applications include chain drives in conveyors, elevators, agricultural machinery, packaging equipment and linear motion systems. It is also used in gearboxes and mechanisms where a specific transmission ratio with few teeth is required. Because of its material, SAE 1045 steel, it withstands moderate loads and surface wear, and can receive heat treatment to increase the hardness of the tooth flanks if the application requires it. It is common in replacements and in the assembly of new equipment.

To correctly select this sprocket, check that the chain pitch matches 3/4" and that the number of teeth is suitable for the transmission ratio you are looking for. Check the shaft diameter and the hub fastening system: set screw, key or both. Consider the alignment between sprocket and chain, lubrication and chain tension. If the sprocket works under severe conditions, consider heat treatment or a material with greater wear resistance. Correct selection prevents premature failures and noise.

If you need an equivalent sprocket, the most practical thing is to send us the current part number, the number of teeth, the pitch and a photo or sketch with the main dimensions: outside diameter, hub diameter, bore and width. With that data we can identify the part or suggest an alternative from our line. We can also look for another size within the 3/4" pitch series or a compatible alternative. Do not hesitate to ask us about other sizes in the 3/4" pitch series.
