A double sprocket with hub, 3/4" pitch and 28 teeth, machined from SAE 1045 steel. This sprocket lets you run two chains side by side from one shaft position. The two tooth rings share a central hub, so you get a single mounting point instead of two separate sprockets. It belongs to the 3/4" pitch series that MR supplies for power transmission drives.

The code tells you the main specs: 3/4" is the chain pitch and Z28 means 28 teeth (z=28). "Double with hub" describes the build: two toothed sections joined to one hub that fits on the shaft. That arrangement keeps both chain runs aligned and simplifies assembly, because you only need one fit on the shaft. It is common in chain conveyors, bucket elevators, drag lines and any machine where two chains must move at the same speed. It also helps when axial space is tight, since you avoid a second sprocket and its fastening.

When selecting, confirm the chain pitch matches 3/4" and that 28 teeth gives the transmission ratio you need. Check the shaft diameter and how the hub will be secured before mounting. After installation, verify alignment with the driven sprockets to prevent uneven wear. Proper lubrication and correct chain tension also help the assembly last.

If you need a different tooth count or another hub style, send the part number MR-PINON-DOBLE-3-4-Z28 or the full designation by WhatsApp. We can look for an equivalent in the 3/4" pitch series or review a custom manufacturing option. We can also tell you whether it will work with an ANSI chain of the same pitch.

MR supplies this sprocket as part of its power transmission line. If you have questions about selection, mounting or chain compatibility, message us on WhatsApp with the item part number. Quotes are prepared from the part number, so you do not have to search for equivalents on your own.
