This double sprocket with hub is identified by the code MR-PINON-DOBLE-3-4-Z76. It runs on 3/4" pitch roller chain and carries 76 teeth, giving the drive ratio when paired with another sprocket of the same pitch. The body is SAE 1045 steel, and the hub lets you mount it straight onto a shaft.
The 3/4" pitch sets the chain size it accepts. With 76 teeth, the sprocket defines the speed relationship in the drive. The double row of teeth shares the load and keeps the two chain strands aligned. The hub is the mounting point: it can be fixed to the shaft with a key or a set screw, depending on how the equipment is built.
Typical installations are low-speed, high-torque drives. You will find this sprocket on chain conveyors, bucket elevators, and machinery in cement, mining, food processing and woodworking. It also suits material handling systems that need a large reduction on 3/4" pitch chain, especially when the sprocket goes on a keyed shaft and a locally sourced replacement is preferred.
When selecting, confirm three things: the chain pitch (3/4"), the tooth count (76), and the shaft diameter at the hub. Also check how the hub fastens, whether by key, set screw or flange. At assembly, align the sprockets and set chain tension following the equipment maker's instructions. Lubrication and regular wear checks help the drive last.
Need a different tooth count, pitch or hub style? We can source it. MR Industrial Accessories LLC manufactures split plummer block housings, roller chains and sheaves, and supplies bearings, seals, lubrication and power transmission parts. To ask for an equivalent, send the code MR-PINON-DOBLE-3-4-Z76 or the shaft and chain dimensions.

Frequently asked questions
- What does "double with hub" mean?
- It means the sprocket has two toothed rings made as one piece with a central hub. The hub is what mounts on the shaft, using a keyway or set screw, and it adds rigidity and transmission capacity compared with a single sprocket.
- Can I order it with a different number of teeth?
- Yes. We can source 3/4" pitch sprockets with other tooth counts and hub types. Send the current code and the dimensions you need on WhatsApp, and we will quote the variant.
- How do I know if it is compatible with my chain?
- The pitch must match: this sprocket is for 3/4" pitch chain. Also check the number of teeth and the shaft diameter. If you have any doubts, send us the chain and shaft data and we will advise you.
