The simplex sprocket with hub, 3/8" pitch and 43 teeth is a sprocket supplied by MR Accesorios Industriales, designed to transmit motion in 3/8" pitch chains. Its integrated hub allows it to be mounted directly on the shaft with a keyway or set screw, without the need for additional bushings. It is used in low and medium speed drives where a smooth, quiet reduction is required.

This sprocket is designated as Simplex sprocket 3/8" Z43 and belongs to the 3/8" pitch series. Its main attributes are: pitch 3/8", 43 teeth, material SAE 1045 steel and type simplex sprocket with hub. The hub is the central protruding part that allows direct mounting on the shaft, with a bore diameter that is adjusted according to the requested size. SAE 1045 steel is a carbon steel with good machinability and strength, suitable for moderate power transmission.

It is used in a wide variety of industrial applications: chain conveyors, agricultural machinery, packaging equipment, lifting systems and machinery drives in general. Being a 43-tooth sprocket, it is common in transmission ratios where the speed of the driven shaft is reduced relative to the driving shaft. It is also used as an idler or return sprocket in long chain runs.

To correctly select this sprocket, take into account the chain pitch (3/8"), the number of teeth (43) and the shaft diameter where it is mounted. The hub allows it to be fastened with a key or set screw, and it is important to verify alignment with the driving sprocket to avoid premature wear. If you need a different ratio, you can ask about other numbers of teeth within the same series.
