The simplex sprocket 3/4" Z9 is a sprocket that MR Accesorios Industriales supplies, designed to transmit motion in 3/4" pitch chains. Its hub allows mounting on shafts and securing with a set screw or key as required. 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), supplied 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 tangential speed. The hub allows securing the sprocket 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. Due to its material, SAE 1045 steel, it withstands moderate loads and surface wear, and can be heat treated to increase hardness on the tooth flanks if the application demands it. It is common in replacements and in the manufacture of new equipment.

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

If you need an equivalent sprocket or a neighboring size, the most practical 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 supplied line. We can also source custom-made if the volume justifies it. Do not hesitate to ask us about other sizes in the 3/4" pitch series.
