This double sprocket with hub, identified as MR-PINON-DOBLE-3-8-Z39, is a chain drive component made from SAE 1045 steel. It has a 3/8" pitch and 39 teeth, and its two tooth rings are integrated with a central hub for shaft mounting. The combination of pitch and tooth count makes it suitable for medium-duty drives where speed and pulling capacity need to be balanced.
The term double sprocket means the part carries two sets of teeth on one body. A central hub connects them and provides the mounting surface for the shaft. The 3/8" pitch tells you which chain will mesh correctly, while the 39 teeth (z=39) determine the drive ratio when paired with another sprocket. The hub is designed for direct shaft mounting using standard fastening methods.
You will find this sprocket in chain drives on agricultural equipment, conveyors, lifting systems, and production lines. It is often chosen when one input must drive two outputs or when the rotation direction needs to be reversed from a single component. Gear reducers and transmission boxes that require two different ratios on the same shaft also use this configuration. SAE 1045 steel gives the sprocket wear resistance for continuous operation under moderate loads.
When selecting this sprocket, confirm that your chain has a 3/8" pitch and that the 39-tooth count matches your desired drive ratio. Check that the hub diameter and fastening method are compatible with your shaft. Alignment between sprocket and chain, as well as axial play, should be verified. During installation, lubricate the chain and set the tension correctly; too much tension will speed up wear on the teeth and bushings.
If you need a different tooth count or a single sprocket instead of a double one, provide the pitch, number of teeth, and required hub diameter. We can also review material or treatment alternatives. Send the part number MR-PINON-DOBLE-3-8-Z39 or the full description via WhatsApp, and we will quote the option that fits your equipment.

Frequently asked questions
- What does it mean that it is a double sprocket with hub?
- It means the sprocket has two tooth rings in one piece, joined by a central hub. The hub mounts on the shaft and allows fastening. This design is used when you need to transmit motion to two chains or create two different ratios from a single point.
- Which chain corresponds to the 3/8" pitch?
- The 3/8" pitch corresponds to chains of that nominal pitch, and they must match in type and inner width. To ensure compatibility, verify the chain designation and consult us on WhatsApp with the sprocket and chain part numbers.
- Can I request a different number of teeth or a single sprocket?
- Yes. We supply sprockets in different configurations. Tell us pitch, number of teeth, hub type, and shaft diameter. With that data we will quote the single or double variant you need.
