When you need to drive two chains from one shaft, the double sprocket 3/4" Z38 from EMMAR is a practical solution. It is machined from SAE 1045 steel and carries two rows of teeth on a single central hub. With a 3/4" pitch and 38 teeth, it fits medium-to-heavy drive applications.
This sprocket goes by the commercial name Double sprocket 3/4" Z38 and belongs to the 3/4" pitch family. Its construction joins two tooth rings to one hub, so you can run two chains or set up two ratios without adding a second shaft. SAE 1045 steel gives the body strength and allows the teeth to be hardened when needed.
You will find this type of drive in agricultural equipment, conveyors, chain elevators, material handling systems and process lines. Gear reducers and transmission boxes also use it when an extra ratio is required. Before installation, confirm that the chain matches the 3/4" pitch and that the tooth count works with the rest of the drive.
Selection comes down to three basics: chain pitch (3/4"), number of teeth (38) and shaft diameter. The hub must fit the shaft correctly, and you need to plan for the fastening method—key, set screw or taper bushing. Check alignment between sprockets and chain tension; misalignment speeds up wear on both teeth and chain. For high-speed operation, verify balancing.
If you are looking for a replacement, the quickest route is to send the part number MR-PINON-DOBLE-3-4-Z38 or the original sprocket data: pitch, teeth, hub diameter and fastening type. With that information we can check whether a variant in the same series exists or if a custom part makes sense. We can also review switching to a single sprocket with hub if your application allows it.

Frequently asked questions
- What does "double sprocket with hub" mean?
- It means two tooth rings are mounted on one central hub. This lets you drive two chains or create two ratios from a single shaft. The hub is the part that attaches to the shaft and carries the mounting.
- How do I request an equivalent?
- Send the part number MR-PINON-DOBLE-3-4-Z38 or the original sprocket details—pitch, teeth, hub diameter and fastening—by WhatsApp or email. We will review the series and offer an alternative or a custom-made part.
- Can I replace this double sprocket with a single sprocket?
- In some applications, yes. It depends on whether your drive needs two chains or two ratios. Share your setup details and we can evaluate if a single sprocket with hub works for you.
