The double sprocket with hub, 3/8" pitch and 22 teeth is a power transmission component manufactured by EMMAR in SAE 1045 steel. It is used in 3/8" pitch chain systems to transmit motion between shafts, especially when two chains need to be mounted on the same shaft or when mounting space is limited. Its hub allows it to be secured to the shaft with a key or screw, and its double row of teeth offers versatility for different drive arrangements.

This item is a double sprocket with hub, designated as Double sprocket 3/8" Z22. It has a 3/8" pitch and 22 teeth (z=22), and is manufactured in SAE 1045 steel. The double-row configuration with hub means it has two toothed rings integral to a central hub, which allows coupling two 3/8" pitch chains on the same component. The hub facilitates mounting on the shaft by key or set screw, depending on the equipment design.

Typical applications of this sprocket include chain drives in agricultural machinery, conveyors, lifting equipment and transmission systems in general. Being double-row, it is used when transmission capacity needs to be doubled or when two chains need to be synchronized with a single wheel. It is also common in implements where axial space is limited and the number of components is to be reduced.

For mounting, verify that the shaft diameter and keyway match the sprocket hub. Alignment between the sprocket and the driven wheel is essential to avoid premature wear and noise. Select the correct chain pitch (3/8" in this case) and make sure the number of teeth is compatible with the desired transmission ratio. SAE 1045 steel offers good mechanical strength and, if required, can be heat treated to increase surface hardness.

If you need a sprocket with a different number of teeth, another pitch or a single instead of double configuration, we can manufacture it. MR Accesorios Industriales has machining capacity to adapt dimensions. To request an equivalent or a nearby size, send the part number MR-PINON-DOBLE-3-8-Z22 or the technical specifications (pitch, teeth, hub type, material) via WhatsApp and we will quote you promptly.
