The double sprocket 3/8" Z33 is a chain drive sprocket with two toothed rings and a central hub, supplied by MR in SAE 1045 steel. It is used to transmit motion between parallel shafts in equipment where the output must be duplicated or two chains synchronized with a single part. Its 3/8" pitch and 33 teeth place it in the light and medium-duty drive range, typical of agricultural machinery, conveyors and packaging equipment.

This double sprocket has a 3/8" pitch, 33 teeth and is machined in SAE 1045 steel. The "double with hub" designation means it has two toothed rings mounted on a single central hub, with a seat for the shaft. SAE 1045 steel is a medium-carbon material, suitable for hardening and tempering, which gives it good wear resistance in continuous service. MR supplies it with dimensional control on the pitch and tooth profile to ensure correct meshing with the chain.

Typical applications of a double sprocket of this pitch appear in low and medium-power drives: seeders, round balers, belt conveyors, grain elevators, packaging machines and material handling equipment. It is also used in systems where a single chain must drive two mechanisms in parallel, or where the direction of rotation must be reversed with a single component. In those cases, the double toothing simplifies assembly and reduces the number of parts.

To select this sprocket properly, verify that the chain pitch matches 3/8" and that the number of teeth is suitable for the desired drive ratio. Check the shaft diameter and the hub mounting system: keyway, set screw or both. Check the alignment between sprocket and chain, and leave the correct tension to avoid premature wear. If the equipment works with pulsating loads or dusty environments, an additional surface treatment should be evaluated.

If you need a different size, we can supply a sprocket with another number of teeth, another pitch or a hub with special dimensions. For that, send us the current part number, the number of teeth, the pitch and a sketch or sample of the shaft. We can also quote an equivalent if you have the original manufacturer's data. The idea is that you don't end up with the machine stopped for a part that can't be found.
