This double sprocket with hub is a power transmission component that lets two chains run from the same shaft, either side by side or on different planes. The hub provides a solid mounting point on the shaft, which simplifies alignment and keeps the setup stable.
The sprocket is made from SAE 1045 steel and carries the designation Double sprocket 3/4" Z50. That code tells you it has two toothed rings joined to a single central hub. The 3/4" figure is the chain pitch that both rings accept, and the 50 teeth set the transmission ratio. Because the hub mounts directly on the shaft, you can secure it with a keyway, a set screw, or both, depending on how the shaft is prepared.
Use this sprocket where a chain drive has to split its output or keep two branches moving together. Common examples are chain conveyors, agricultural equipment, lifting gear, and production lines that need two coordinated motions. It also works when you want to reverse rotation or drive two separate shafts at the same angular speed.
When choosing the sprocket, confirm that your chain matches the 3/4" pitch and that 50 teeth give the ratio you need. Check the hub bore against your shaft diameter, and make sure the fastening method suits the torque involved. Aligning both tooth rings precisely is important to prevent uneven wear and noise.
If your application calls for a different tooth count, pitch, or hub dimensions, MR can manufacture a custom sprocket. Send the reference MR-PINON-DOBLE-3-4-Z50 or the specifications (pitch, teeth, hub diameter, fastening type) and the team will prepare a quote. You can also ask for an equivalent if you are replacing another brand.

Frequently asked questions
- What does it mean that it is a double sprocket with hub?
- It means it has two toothed rings mounted on a central hub. This allows two chains to mesh simultaneously, either to duplicate the transmission or to synchronize two shafts. The hub makes it easier to fasten to the shaft using a key or set screw.
- Which chain pitch does this sprocket use?
- It uses a 3/4" pitch. Both tooth rings are cut for that pitch, so the same chain type meshes on each side.
- Can I request a different number of teeth or a custom hub?
- Yes. MR can manufacture sprockets with other tooth counts, pitches, or hub dimensions. Send the code MR-PINON-DOBLE-3-4-Z50 or your specifications and the team will quote accordingly.
