When you need to drive two chains from one shaft, a double sprocket with hub gets the job done. This one runs on 1/2" pitch roller chain and carries 19 teeth, so it suits equipment where two lines must move together or where the load is shared across two rows. It is supplied in SAE 1045 steel and is identified by the part number MR-PINON-DOBLE-1-2-Z19.
Break the designation down and you know what you are ordering: double row, 1/2" chain pitch, 19 teeth, hub type. The hub is the raised center section that slides onto the shaft and is held by a key or a set screw, depending on how your machine is built. Because there are two rows of teeth, one sprocket can serve two chains side by side.
You will find this configuration on drive shafts that branch into two chain runs, on agricultural implements that need synchronized motion, and on conveyors, elevators, mills and mixers where a single shaft has to handle more than one chain. The 19-tooth count sets the ratio between the sprocket and whatever it drives, so confirm that figure against your existing setup before ordering.
Fitting is straightforward once the basics line up. Check that your chain is 1/2" pitch, that the hub bore and fixing method match the shaft, and that the sprocket and chain sit in line. Misalignment is the usual cause of short chain and sprocket life, so take a moment to square everything up. Keep the chain lubricated and at the right tension, and the assembly will run as it should.
If the tooth count, pitch or row configuration you need is different, that is not a problem. Send the chain and shaft details along with the part number MR-PINON-DOBLE-1-2-Z19 or the designation Double sprocket 1/2" Z19 through WhatsApp or email, and the team will come back with the correct part or a suitable equivalent.

Frequently asked questions
- Does this sprocket work with a 1/2" pitch chain?
- Yes. It is built for 1/2" pitch roller chain. Confirm your chain matches that pitch, and if you are unsure, send us the chain part number and we will check it for you.
- What is the difference between double and hub in this sprocket?
- Double refers to the two rows of teeth, which let one sprocket drive two chains in parallel. The hub is the central section that mounts on the shaft and is secured with a key or a set screw.
- Can I order a different size?
- Yes. We source sprockets in other pitches, tooth counts and configurations. Send the pitch, number of teeth and shaft dimensions by WhatsApp or email, and we will quote what you need.
