The simplex sprocket 3/4" Z12 is a chain sprocket supplied by MR Accesorios Industriales, 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 equipment design. It is used in conveyors, elevators and agricultural or industrial machinery that works with this chain pitch. Being made of SAE 1045 steel, it offers good resistance to wear and to the loads typical of the drive.

This sprocket has a 3/4" pitch, 12 teeth and is made of SAE 1045 steel. It is a simplex sprocket with hub, which means the toothed rim and the hub form a single piece, with a central bore for mounting on the shaft. The hub provides a larger bearing surface and allows it to be secured with a set screw or key. The 3/4" pitch corresponds to roller chains of that pitch, widely used in medium-speed, moderate-load drives.

Typical applications include belt or roller conveyors, bucket elevators, agricultural machinery, packaging equipment and drive systems in industrial plants. It is also used to replace worn sprockets on production lines that already work with 3/4" pitch. In all cases, it is advisable to verify that the chain pitch matches the sprocket pitch exactly to avoid skipping or premature wear.

To select the correct sprocket, take into account the number of teeth, the shaft diameter and the type of fastening the hub accepts. If the shaft is smaller than the bore, a bushing or sleeve can be used, but always maintaining concentricity. Also check the alignment between sprocket and chain: angular or parallel misalignment accelerates wear on both. Proper lubrication and correct chain tension are key to service life.

If you need a sprocket with a different number of teeth, a different hub diameter or a different pitch, we can source it or find the equivalent size. To do so, send us the part number MR-PINON-SIMPLE-3-4-Z12 or the full designation via WhatsApp and we will provide a quote.
