Description
MR Piñón doble 3/4" Z31 belongs to sprockets and gears, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for Piñón doble 3/4" Z31 and any equivalents.
This double sprocket with hub has a 3/4" pitch and 31 teeth, and is made from SAE 1045 steel. It mounts on a shaft to drive two chains in parallel, with the hub secured by a set screw or key. The 3/4" pitch matches chains of that pitch.
The code MR-PINON-DOBLE-3-4-Z31 identifies a double sprocket: two tooth rings share one central hub, so a single part can drive two chains side by side. The hub fits onto the shaft and is locked with a set screw or key, depending on how the equipment is built. The 3/4" pitch sets the distance between teeth and the chain type that will mesh with it.
You will find this sprocket in chain drives for agricultural machinery, conveyors, elevators, mills and general industrial equipment. It suits setups where two chain lines must move together, such as seeders, harvesters or drag systems, and also appears in machine tools and material handling equipment that synchronize two chain runs from one drive wheel.
When selecting the part, confirm the chain pitch (3/4"), the number of teeth (31) and the shaft diameter where it will be mounted. The hub must match the shaft and the securing method. Check alignment between sprocket and chain, and keep lubrication in good condition. Under high load, inspect for wear periodically and replace the sprocket if the teeth show deformation.
If you need a different tooth count, another pitch or a different hub size, MR can manufacture it. MR also produces split plummer block housings, ANSI chains and sheaves, and distributes bearings, seals and power transmission products. To request an equivalent, send the code MR-PINON-DOBLE-3-4-Z31 or the characteristics you require and the team will advise you.

Frequently asked questions
- What does it mean that it is a double sprocket with hub?
- It means it has two tooth rings on the same central hub. The hub is the part that mounts on the shaft and is secured with a set screw or key. Thus, a single part can drive two chains in parallel, which simplifies assembly and reduces components.
- How do I request a quote or an equivalent?
- Write on WhatsApp and mention the code MR-PINON-DOBLE-3-4-Z31. If you are looking for an equivalent, send the shaft measurements, the chain pitch and the number of teeth. The team will quote the manufacturing options.
- What should I check before installing this sprocket?
- Verify the chain pitch (3/4"), the number of teeth (31), the shaft diameter and the hub securing method. Also check alignment between sprocket and chain, and ensure proper lubrication.
