The double sprocket 1/2" Z13 is a power transmission component used to drive two chains in parallel from a single shaft. Its hub allows it to be mounted directly on the shaft, and its 13 teeth make it suitable for short transmission ratios. It is a part sold by MR Accesorios Industriales, designed for equipment that needs to synchronize two chain runs with the same pitch.
This item is a double sprocket with hub, made of SAE 1045 steel, with 1/2" pitch and 13 teeth. The designation Double sprocket 1/2" Z13 indicates that it is a toothed wheel with two rows of the same number of teeth, mounted on a common hub. The 1/2" pitch corresponds to ANSI 40 chain, and the 13 teeth define the transmission ratio when combined with another wheel of the same pitch. The hub allows it to be fixed to the shaft with a key or screw, depending on the equipment design.
It is used in chain drives where two lines need to be driven at once, such as in roller conveyors, packaging machines, wrapping equipment and lifting systems. It also appears in agricultural implements and in production lines that need to keep two sections synchronized. Being double, it allows the tension of each run to be set independently or doubles the drive capacity without adding a second sprocket to the shaft.
To select it, check that the chain pitch matches the sprocket pitch, that the number of teeth is suitable for the required speed and torque, and that the shaft diameter fits the hub. The alignment of the two rows with the chains is critical to avoid uneven wear. If the sprocket works in a dusty or humid environment, periodic lubrication and protection should be provided. MR sells this model in SAE 1045 steel, which gives it good wear resistance.
If you need a different size, we can source a double sprocket with a different number of teeth, a different pitch or a hub with a different shaft diameter. To do so, send us the part number MR-PINON-DOBLE-1-2-Z13 or the full designation by WhatsApp, along with the size you are looking for. We can also quote an equivalent if you send us the shaft dimensions, the chain pitch and the number of teeth. Our role as seller allows us to adapt the part to your equipment.

Frequently Asked Questions
- What does double with hub mean?
- It means it has two toothed rows mounted on a single hub. The hub is the central body that is fixed to the shaft, and the two rows allow two chains to be driven in parallel with the same pitch and number of teeth.
- What type of chain is this sprocket for?
- It is designed for 1/2" pitch chains, which correspond to the ANSI 40 series. It is important to verify that the chain you are going to use has exactly that pitch to ensure correct meshing and avoid premature wear.
- Can I request a special size?
- Yes, since it is sold by MR we can source the sprocket in other sizes. Send us the part number MR-PINON-DOBLE-1-2-Z13 by WhatsApp along with the characteristics you need, such as number of teeth, shaft diameter or pitch, and we will quote you.
