The simplex sprocket 3/4" Z28 is a sprocket supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. It has 28 teeth and a hub, and is machined from SAE 1045 steel. It is used in power transmissions where a durable sprocket with controlled dimensions is required, and it can be combined with ANSI chains of the same pitch to build the complete assembly.

This item is a simplex sprocket with hub, 3/4" pitch and 28 teeth (z=28), supplied by MR in SAE 1045 steel. The designation Simplex sprocket 3/4" Z28 summarizes its main data: a single toothed plate, with a central hub for shaft mounting, and a 3/4" chain pitch. SAE 1045 material is a carbon steel commonly used in machined parts that require good wear resistance and toughness. The hub allows the sprocket to be secured to the shaft with a key or set screw, depending on the equipment design.

Typical applications for a sprocket of this type are in chain drives for agricultural machinery, conveyors, elevators, mixers and power transmission equipment in general. Being 3/4" pitch, it is used with ANSI chains of that pitch, which are common in moderate-speed, medium-load drives. The 28-tooth count defines the transmission ratio when combined with another sprocket of the same pitch.

To correctly select this sprocket, take into account the chain pitch (3/4"), the number of teeth (28) and the shaft diameter where it is mounted, which must match the hub bore. Also check the type of fixing: keyway, set screw or both. During assembly, make sure to align the sprocket with the driven sprocket to avoid irregular wear and noise. Proper lubrication of the chain and sprocket extends the service life of the assembly.

If you need a sprocket with a different number of teeth, another pitch or a different hub size, we can source the equivalent. To do so, send us the part number MR-PINON-SIMPLE-3-4-Z28 or the full designation by WhatsApp, along with the chain and shaft data. That way we can quote the exact part or a variant compatible with your equipment.

At MR Accesorios Industriales we supply this type of sprocket as well as chains, bearings and transmission accessories. If your inquiry is for a nearby size or a replacement, write to us on WhatsApp and we will reply with the technical information you need to make your purchase decision.
