The double sprocket with hub, 1/2" pitch and 18 teeth, is a power transmission component mounted on shafts to transmit motion through chains. Its double-row design allows driving two chains in parallel, which is useful in applications where synchronization or load distribution is required. Supplied by MR in SAE 1045 steel, it is designed to withstand the wear of continuous operation in industrial machinery.

This item is a double sprocket with hub, identified as Double sprocket 1/2" Z18. Its technical attributes are: pitch 1/2", number of teeth 18 (z), material SAE 1045 steel and type double sprocket with hub. The hub allows it to be fixed to the shaft by keyway or set screw, and the double configuration allows the mounting of two 1/2" pitch chains. It is a part supplied by MR, designed to be integrated into chain drive systems.

Typical applications include roller conveyors, bucket elevators, packaging machines, material handling equipment and drives for agricultural or industrial machinery. Because it has a double row, it is used when higher torque must be transmitted or when two chain strands must move in a synchronized way. It is also common in systems where axial space is limited and a single component with two rows is preferred.

To correctly select this sprocket, verify that the chain pitch is 1/2" and that the number of teeth is compatible with the desired transmission ratio. The hub must match the shaft diameter and the fastening system (keyway or set screw). It is important to align both rows with the corresponding chains and to control tension to avoid premature wear. SAE 1045 steel offers good mechanical strength and hardenability, suitable for continuous service.

If you need a sprocket with a different number of teeth, a different pitch or a single instead of double configuration, we can source an equivalent alternative. To do so, send us the part number MR-PINON-DOBLE-1-2-Z18 or the full designation by WhatsApp, along with the pitch, teeth and shaft diameter data. That way we can quote the exact part or a nearby size that fits your machine.

At MR Accesorios Industriales we supply this type of component with more than 80 years of experience in the field. If you have doubts about compatibility with your chain or mounting on the shaft, ask us by WhatsApp and we will advise you. Send the part number MR-PINON-DOBLE-1-2-Z18 and we will reply with the quote.
