The double sprocket 3/4" Z28 is a power transmission sprocket that MR Accesorios Industriales supplies with a built-in hub. It is used to drive two chains in parallel from a single shaft, with a 3/4" pitch and 28 teeth. It is machined from SAE 1045 steel, which gives it good resistance to wear and fatigue. It is a part designed for equipment where two chain runs need to be synchronized without adding a second sprocket to the shaft.
This item is a double sprocket with hub, 3/4" pitch and 28 teeth (z=28), machined from SAE 1045 steel. The designation Double sprocket 3/4" Z28 indicates the chain pitch and the number of teeth; the construction type is double with hub, meaning the two toothed rings are joined to a central hub that mounts on the shaft. It is a part from the power transmission line that MR supplies, within the 3/4" pitch series.
Typical applications appear in chain conveyors, bucket elevators, drag lines and machines where two chain runs must move at the same speed. By sharing the hub, the double sprocket maintains alignment between both chains and simplifies assembly: a single fit to the shaft instead of two. It is also used in dual-drive equipment where axial space is limited.
To select it, verify that the chain pitch matches the 3/4" pitch of the sprocket and that the number of teeth is suitable for the desired transmission ratio. Check the shaft diameter and the hub fastening system before mounting, and check the alignment between the sprocket and the driven sprockets to avoid uneven wear. Correct lubrication and adequate chain tension extend the life of the assembly.
If you need a nearby size, a different number of teeth or a hub variant, send us the part number MR-PINON-DOBLE-3-4-Z28 or the full designation by WhatsApp. With that data we can locate the equivalent within the 3/4" pitch series or evaluate a custom manufacturing. We can also advise you if the sprocket will work with an ANSI chain of the same pitch.
At MR Accesorios Industriales we supply this type of sprocket and have more than 80 years of experience in power transmission. If you have questions about selection, mounting or compatibility with your chain, write to us by WhatsApp with the item part number and we will advise you. Quotes are made with the part number at hand, so you don't need to look up equivalents on your own.

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 single central hub. This way you can drive two chains in parallel from a single point on the shaft, with a single fastening and without adding a second sprocket.
- What type of chain is this sprocket for?
- It is designed for 3/4" pitch chains. Before mounting it, verify that your chain pitch matches that value and that the number of teeth is the one your transmission ratio requires.
- Can I request a different number of teeth or a different size?
- Yes. Send us the part number MR-PINON-DOBLE-3-4-Z28 or the designation by WhatsApp and we will help you locate a nearby size within the 3/4" pitch series or evaluate a special manufacturing.
