This item is a simplex sprocket with hub, 3/4" pitch and 45 teeth (z). It is made of SAE 1045 steel and supplied by MR, which gives it a suitable strength base for continuous service. The designation Simplex sprocket 3/4" Z45 summarizes its main data: a single toothed plate, 3/4" pitch and 45 teeth. The hub allows it to be secured to the shaft with the usual fastening elements. It is a part of the power transmission line that MR commercializes and sells.
It is used in 3/4" pitch chain drives in industrial equipment: conveyors, elevators, process machines and motion systems where a specific transmission ratio is required. Being a 45-tooth wheel, it is usually used as a driven or output wheel in assemblies where the goal is to reduce speed or multiply torque. It is also found in agricultural and industrial machinery applications that work with chains of that pitch.
To mount it, verify that the chain pitch matches the 3/4" pitch of the sprocket and that the number of teeth is suitable for the desired ratio. The hub must be aligned with the shaft and with the driving wheel to avoid uneven wear. Since it is made of SAE 1045 steel, the bore or keyway can be machined according to the equipment's needs. If you have doubts about selection, consult us with your machine data.
If you need an equivalent sprocket, send us the original part number, the number of teeth and the chain pitch. We can also look for another size within the line or a compatible alternative. MR Accesorios Industriales commercializes split plummer block housings, ANSI chains and pulleys, in addition to selling bearings and transmission products. Write to us by WhatsApp and we will quote you.
To finish, send the part number MR-PINON-SIMPLE-3-4-Z45 or the one of the part it replaces by WhatsApp. With that data we will provide the quote. If the sprocket is mounted in an assembly, it is advisable to also send the shaft and chain characteristics to avoid compatibility errors.
