The double sprocket 3/8" Z40 is a chain wheel supplied by MR Accesorios Industriales, designed to transmit motion in 3/8" pitch chains. It has 40 teeth and a double row with hub, which allows it to be mounted on shafts and to engage two chains in parallel. It is used in conveyors, agricultural machinery and transmission equipment that needs to synchronize movements with a defined transmission ratio.
This item is a double sprocket with hub, machined in SAE 1045 steel, with 3/8" pitch and 40 teeth. The designation Double sprocket 3/8" Z40 indicates that it is a part with two toothed crowns integral to a central hub, suitable for mounting on a shaft and securing with a key or set screw depending on the equipment design. The 3/8" pitch corresponds to the chain that meshes with the teeth; the number of teeth defines the transmission ratio when combined with another sprocket or wheel of the same chain.
Typical applications of a double sprocket of this type appear in chain conveyors, bucket elevators, agricultural machinery, packaging equipment and transmission systems where two chain strands need to be driven with a single part. It is also used in gearboxes and synchronization mechanisms that require a chain wheel with hub to transmit torque from the shaft. As a product we supply, adaptation to specific machining needs can be evaluated within the limits of the material and the pitch.
To correctly select this sprocket, verify that the chain pitch is 3/8" and that the number of teeth is compatible with the desired transmission ratio. Check the shaft diameter and the hub fastening system, and make sure the overall width of the double sprocket fits the available space. During assembly, align both crowns with the corresponding chains and check the tension to avoid premature wear. If the equipment operates with variable loads, ask about heat treatment or additional machining.
If you need an equivalent or a nearby size, the most practical thing is to send us the part number MR-PINON-DOBLE-3-8-Z40 or the full designation by WhatsApp. From there we can check whether there is another number of teeth, a different pitch or a hub variant that fits your equipment. We can also evaluate supplying a custom part if the standard sprocket does not cover the application. The more data you provide — pitch, teeth, shaft diameter and fastening type — the faster the response.

Frequently Asked Questions
- What does it mean that it is a double sprocket with hub?
- It means it has two toothed crowns mounted on the same hub. This allows a single part to mesh with two chains in parallel, which is useful for synchronizing movements or duplicating the transmission on the same shaft.
- What material is this sprocket made of?
- It is machined in SAE 1045 steel, a carbon steel with good mechanical strength and machinability. It is suitable for power transmission applications under normal working conditions, and additional treatment can be evaluated depending on the use.
- How do I request a different size or an equivalent?
- Send us the part number MR-PINON-DOBLE-3-8-Z40 or the full designation by WhatsApp, along with the pitch, number of teeth and shaft diameter you need. With that data we will quote a variant or evaluate a custom supply.
