This 18-tooth double sprocket with hub is made from SAE 1045 steel and runs on 5/8" pitch chain. Its two rows of teeth let you drive two chain strands from one point on the shaft, which is useful when space is tight or when a single wheel has to handle two drives. MR supplies it under part number MR-PINON-DOBLE-5-8-Z18.

The design combines a central hub that sits on the shaft with two toothed rings side by side. The hub is what the shaft passes through and where the sprocket gets fastened; the paired teeth are cut to engage two chains at once. This makes it a power transmission component rather than a simple single-strand sprocket.

You will find this type of sprocket in drive lines that move two chain strands together: roller conveyors, chain elevators, packaging equipment and machines that run in continuous motion. It also appears in gearboxes and similar mechanisms where concentrating two drives at one shaft position simplifies the layout.

Before ordering, confirm that your chain is 5/8" pitch and that 18 teeth give the ratio you need. Check the shaft diameter and how the hub will be secured, and make sure the sprocket and chain will line up properly to avoid uneven wear. If the sprocket has to sit at an exact spot, account for the overall width of the double toothing and the room available on the equipment.

If this size does not fit your application, other tooth counts or pitches from the same line can be reviewed. To move forward, send the current part number, the number of teeth you require, the chain pitch, and a photo or sketch of the assembly. That information helps us point you to a suitable alternative.
