The double sprocket 3/8" Z13 is a double-row chain sprocket with hub, supplied by MR, in SAE 1045 steel. It is used in 3/8" pitch chain drives to move two chains in parallel from the same shaft, typical in conveyors, elevators and compact transmission machines. Its hub allows mounting directly on the shaft with key and screw, without additional bushings. If you need to replace it or adapt it to your equipment, send us the code and we will quote.

This item is a double sprocket with hub, 3/8" pitch and 13 teeth, in SAE 1045 steel. The designation Double sprocket 3/8" Z13 indicates the chain pitch, the number of teeth and the double-row configuration with hub. SAE 1045 material is a carbon steel with good machinability and strength, suitable for tooth machining and subsequent heat treatment if the use requires it. The integrated hub facilitates mounting on the shaft and allows transmitting torque without intermediate parts.

It is used in chain drives where two lines need to be moved in parallel, such as roller conveyors, bucket elevators, packaging machines and compact transmission equipment. It also appears in power distribution systems where a single shaft must drive two synchronized chains. Due to its 3/8" pitch and 13 teeth, it is common in low and medium speed applications with moderate loads, where a specific transmission ratio is sought without increasing the size of the assembly.

To select it, verify 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, and make sure the alignment between sprocket and chain is correct to avoid premature wear. If the original sprocket has heat treatment or special tolerances, indicate it when requesting the quote to evaluate custom manufacturing.

If you need an equivalent or a nearby size, such as another number of teeth or a different pitch, send us the current code and the shaft measurements. With that data we can offer you an alternative from our line or evaluate special manufacturing. We can also advise you on the type of steel and treatment according to the load and speed of your equipment.
