This double sprocket with hub is designed for positive drive and synchronization in industrial equipment. It mounts on shafts and couples with other transmission components, making it suitable for agricultural machinery, conveyors, and systems that require reliable motion transfer.
The sprocket is made of SAE 1045 steel and has a 3/4" pitch with 12 teeth. Its double-row configuration consists of two toothed rings integrated with a central hub, which allows driving two chains at once or increasing transmission capacity on a single shaft. The SAE 1045 material offers wear resistance and toughness for continuous service.
Typical uses include chain conveyors, bucket elevators, agricultural machinery, packaging equipment, and synchronization mechanisms. It is also found in production lines that need two chain strands driven by one sprocket. The hub enables fastening by key or set screw, depending on the shaft design.
When selecting this sprocket, confirm that the chain pitch is 3/4" and that the 12 teeth match the required transmission ratio. Proper alignment of the chain rings with the chains and correct tension are important to avoid premature wear. If you need a different tooth count or pitch, we can help you find the right option.

Frequently asked questions
- What does "double with hub" mean?
- It means the sprocket has two toothed rings on a central hub. This allows driving two chains in parallel or increasing transmission capacity on one shaft, which is useful for synchronization or higher torque applications.
- How do I request a different size or an equivalent?
- Send the part number MR-PINON-DOBLE-3-4-Z12 by WhatsApp or email, along with the pitch, number of teeth, shaft diameter, and fastening type you need. Our technical team will advise you and provide a quote for the most suitable option.
- What should I check before installing this sprocket?
- Verify that the chain pitch is 3/4" and the tooth count is 12. Ensure the hub is properly fastened to the shaft by key or set screw, and that the chain rings are aligned with the chains. Check chain tension to avoid premature wear.
