A double-row sprocket with a hub, identified as Double sprocket 1/2" Z20 and part number MR-PINON-DOBLE-1-2-Z20, is a power transmission part that fits onto a shaft and engages 1/2" pitch chains. The two toothed rings run side by side, and the central hub is the section that clamps or keys to the shaft. Compared with a single-row sprocket in the same pitch, this arrangement lets the drive handle higher torque or run two chains in parallel. MR supplies this sprocket for maintenance and assembly work on industrial drives.
Key specifications for this item: pitch 1/2", tooth count 20, material SAE 1045 steel, and type double sprocket with hub. SAE 1045 is a medium-carbon steel that machines well and can be heat treated later if the application calls for it. The hub is the central body that mounts to the shaft; the two toothed rings are what make it a double sprocket.
You will find this type of sprocket in chain drives on production machinery, conveyors, elevators, packaging lines, and linear motion systems. It is chosen when the drive needs more capacity without switching to a larger chain pitch, or when two parallel chains have to move together from one shaft. Gearboxes and transmission cases that need two toothed outputs also use it.
Before mounting, confirm that the shaft diameter and the hub fastening method match your equipment. Check that the sprocket and chain line up correctly; poor alignment leads to uneven wear. When selecting a replacement, review pitch, number of teeth, hub style, and material. For high-load or high-speed duty, heat treatment or an alloy steel may be required, and that is assessed case by case.

Frequently asked questions
- What does double with hub mean?
- It means two toothed rings are arranged in parallel, with a central hub that mounts to the shaft. The hub is the part that secures to the shaft, and the two rings allow higher torque transmission or two chains to be driven at once.
- What material is this sprocket made of?
- It is made of SAE 1045 steel, a medium-carbon grade. It machines well and can be heat treated if the application requires it. Final properties are confirmed with the technical data sheet.
- Can I request a different size or an equivalent?
- Yes. Send the part number or designation via WhatsApp and we will quote the same part or an alternative with another pitch, tooth count, or hub type. Custom manufacturing to drawing or sample is also offered.
