The double sprocket 3/4" Z30 is a chain wheel supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. It has 30 teeth and a double row of teeth with a central hub, which allows it to be mounted on shafts and to couple two chains in parallel. It is used in power transmission equipment where movements need to be synchronized or the output duplicated.
This item is a double sprocket with hub, machined in SAE 1045 steel, with 3/4" pitch and 30 teeth. The designation Double sprocket 3/4" Z30 means exactly that: two chain rings integral with a central hub, for 3/4" pitch chains. The SAE 1045 steel gives it wear resistance and toughness for continuous service. The hub allows it to be fixed to the shaft with a key or set screw, depending on the equipment design.
It is used in chain drives in agricultural machinery, conveyors, elevators, mixers and material handling equipment. It also appears in systems where the drive needs to be duplicated or the direction of rotation reversed with a single wheel. It is common in machines that already work with 3/4" pitch chains and require a 30-tooth sprocket with double output.
To select it, check that the chain pitch matches 3/4" and that the number of teeth is suitable for the desired transmission ratio. Check the shaft diameter and the hub fastening system. If the sprocket works in a dusty or dirty environment, consider periodic lubrication and alignment control between sprockets to avoid uneven wear.
If you need a nearby size, a different number of teeth or a single sprocket instead of the double one, we can source it. Send us the part number MR-PINON-DOBLE-3-4-Z30 or the full designation by WhatsApp and we will quote you. We can also advise you if you have doubts about compatibility with your chain or mounting on the shaft.
At MR Accesorios Industriales we supply split plummer block housings, ANSI roller chains and pulleys (sheaves), as well as bearings, seals and power transmission. More than 80 years of experience back us. Write to us by WhatsApp with the product part number and we will reply with the quote.

- Can it be used with a standard 3/4" pitch chain?
- Yes, it is designed for 3/4" pitch chains. Check that the chain is the same pitch and that the number of teeth matches the transmission ratio you need. If you have doubts, ask us with the part number.
- Do you make custom sprockets?
- Yes, we can source sprockets with other sizes, number of teeth or hub type. Send us your requirement by WhatsApp and we will quote you. We can also source single sprockets if you do not need the double one.
