The double sprocket 3/8" Z17 is a power transmission chain sprocket that is mounted on shafts to drive 3/8" pitch chains. Its double-row design with hub allows transmitting motion in two chain lines simultaneously or doubling the load capacity.

This item is a double sprocket with hub, 3/8" pitch and 17 teeth, machined from SAE 1045 steel. The designation Double sprocket 3/8" Z17 indicates that it has two tooth rings integral to a central hub, with the same number of teeth on both. The 3/8" pitch defines the compatible chain, and the 17 teeth determine the transmission ratio when combined with another sprocket or wheel. The hub allows mounting it on the shaft with a suitable fastening system, depending on the equipment design.

It is used in chain drives of agricultural machinery, conveyors, bucket elevators, mixers and material handling equipment. It also appears in mechanisms where the chain line needs to be doubled, as in some dual-branch drives or synchronization systems. It is a common replacement part in plants that work with 3/8" pitch chains and need to replace the sprocket without modifying the rest of the assembly.

To select the sprocket, check that the chain pitch matches 3/8" and that the number of teeth is suitable for the desired transmission ratio. Check the shaft diameter and the hub fastening system: keyway, set screw or taper bushing, as applicable. Also check the alignment between sprockets and the chain tension, because poor alignment accelerates wear on teeth and chain. If space allows, choose a sprocket with more teeth to reduce speed and increase torque.

If you need a different size, we can manufacture a double sprocket with a different number of teeth or for another chain pitch. To order an equivalent or a nearby size, send us the part number MR-PINON-DOBLE-3-8-Z17 or the full designation, along with the pitch, the number of teeth and the required shaft diameter. You can also send a photo or a dimensioned sketch of the original part. With that data, we will quote the alternative that best suits your equipment.
