The simplex sprocket 3/4" Z11 is a toothed wheel supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. It has 11 teeth and a hub, and is machined in SAE 1045 steel. It is used in power transmissions where a small, robust sprocket with good shaft support is needed. If you need to replace it or build a new transmission, this part number gives you the exact size to order.

This item is a simplex sprocket with hub, 3/4" pitch and 11 teeth (z), machined in SAE 1045 steel. The designation says it all: simplex because it has a single row of teeth, with hub because the hub protrudes from the disc and allows mounting on the shaft with a longer support. The 3/4" pitch defines the chain it meshes with; the 11 teeth are the number of teeth on the sprocket. It is a power transmission part, not an optical precision component: it is selected by pitch, teeth and shaft diameter.

Typical applications of a 3/4" pitch sprocket with 11 teeth appear in low-speed, high-torque transmissions: chain conveyors, bucket elevators, agricultural machinery, material handling equipment and industrial machinery drives in general. It is also used as an output sprocket in gearboxes and gearmotors, or as an idler sprocket in systems where space is limited. In all cases it is advisable to verify that the chain is of the same pitch and that the number of teeth is compatible with the desired transmission ratio.

To mount and select this sprocket, take into account the shaft diameter: the hub is machined with the bore and keyway according to the shaft where it will be mounted. Also verify the chain pitch, which must be 3/4", and the number of teeth, which in this case is 11. If the sprocket works with a new chain, check the wear of the old chain; mixing a worn chain with a new sprocket accelerates wear on both. Alignment between sprockets and correct chain tensioning are key for the assembly to last.

If you need an equivalent or a nearby size, the most practical thing is to send us the full part number by WhatsApp. We can check whether there is another sprocket in the same series with a different number of teeth, or whether it is better to move to a larger pitch. We can also supply the sprocket with the bore and keyway made to your shaft size. The more data you give us — pitch, teeth, shaft diameter and chain type — the faster we can quote you.

This sprocket is supplied by MR. If you already have the part number at hand, send it by WhatsApp and we'll send you the quote. If you are not sure about the size, tell us what chain you use and for what equipment, and we'll help you identify the replacement.
