This double sprocket with hub is identified as Double sprocket 1/2" Z18 and carries the part number MR-PINON-DOBLE-1-2-Z18. It is a power transmission component that mounts on a shaft and drives chain. The double-row configuration lets two 1/2" pitch chains run in parallel, which suits setups that need synchronization or load sharing. The sprocket is supplied in SAE 1045 steel.
Key technical data: pitch 1/2", number of teeth 18 (z), material SAE 1045 steel, type double sprocket with hub. The hub is fixed to the shaft by keyway or set screw. Because there are two rows, two 1/2" pitch chains can be mounted on the same body.
Typical uses include roller conveyors, bucket elevators, packaging machines, material handling equipment, and drives on agricultural or industrial machinery. The double row is chosen when more torque must be transmitted or when two chain strands need to move together. It also fits where axial space is limited and a single two-row component is preferred.
When selecting this sprocket, confirm that the chain pitch is 1/2" and that 18 teeth give the transmission ratio you need. Match the hub to the shaft diameter and to the fastening method, keyway or set screw. Align both rows with their chains and check tension to avoid premature wear. SAE 1045 steel provides good mechanical strength and hardenability for continuous service.
If you need a different tooth count, another pitch, or a single-row version, an equivalent alternative can be sourced. Send the part number MR-PINON-DOBLE-1-2-Z18 or the full designation by WhatsApp, together with pitch, teeth, and shaft diameter, so the exact part for your machine can be quoted. If you are unsure about chain compatibility or shaft mounting, ask by WhatsApp and the team will advise.

Frequently asked questions
- What does "double with hub" mean on this sprocket?
- It means the body has two toothed rows and a central hub for shaft mounting. This allows two chains to be driven in parallel or more torque to be transmitted with one component.
- Which chain does this sprocket fit?
- It is made for 1/2" pitch chains. Check that the pitch matches exactly to prevent premature wear or chain skipping.
- Can I request a different size or configuration?
- Yes. If you need another number of teeth, a different pitch, or a single-row sprocket, send the details by WhatsApp and an equivalent option can be quoted.
