The double sprocket 3/8" Z19 is a power transmission component used to drive two chains in parallel from the same shaft. Its hub allows direct mounting on the shaft, and its 19 teeth place it in a medium transmission ratio. It is a part that MR supplies, intended for replacement in production lines, conveyors and machines where two chain strands need to be synchronized.

This item is a double sprocket with hub, made of SAE 1045 steel, with 3/8" pitch and 19 teeth. The designation Double sprocket 3/8" Z19 indicates that it is a part with two toothed rings integral to a central hub, which allows two chains to be driven simultaneously. The 3/8" pitch corresponds to chains of the ASA 35 series, and the 19 teeth define the pitch diameter and tangential speed. The hub facilitates mounting on shafts with keyway or screw fastening.

It is used in applications where motion must be transmitted to two chains at the same speed, such as double-chain conveyors, packaging machines, bottling equipment and lifting systems. It also appears in assembly lines and machine tools that need to synchronize two strands. As a part that MR supplies, it can be adapted to specific machining needs, such as adding keyways or modifying the hub.

To select this sprocket correctly, take into account the chain pitch (3/8" in this case), the number of teeth (19) and the diameter of the shaft where it is mounted. The hub must have a bore that matches the shaft, and a keyway is commonly required to transmit torque. Also verify the alignment between the two chain strands and proper lubrication. If you need a different number of teeth or a different pitch, it can be obtained custom-made.

If you are looking for an equivalent or a nearby size, the most practical thing is to send us the part number MR-PINON-DOBLE-3-8-Z19 or the full designation. From there we can confirm other combinations of teeth or pitches, or offer you a compatible replacement. We can also advise you on the appropriate chain for this sprocket and the fastening systems. The idea is that you don't end up with a component that doesn't fit your machine.
