The RUADIGON X-13/120 coupling, also identified as X-120/120, is a power transmission component made up of a normal hub and a solid hub. It is used to join two shafts and transmit motion between them in industrial equipment, and its design allows it to absorb small misalignments depending on the assembly. At MR Accesorios Industriales we carry it as part of our coupling line for maintenance and replacement.
This item is a coupling from the RUADIGON X series, designated X-13/120 and equivalent to X-120/120. It is made up of a normal hub and a solid hub, which are the two parts that form the assembly. It is not a complete flexible coupling with a built-in elastic element, but rather the hubs that mate with each other. To confirm dimensions, shaft diameters and tolerances, consult the manufacturer's data sheet.
Couplings of this type are used in transmission lines where a motor or gearbox needs to be linked to a machine. They appear in conveyors, pumps, fans, mixers and process equipment in general. The combination of normal hub and solid hub responds to configurations where a rigid or semi-rigid connection between shafts is sought, depending on the assembly design and service conditions.
To select the correct coupling, take into account the diameter and length of the shaft at each end, the torque to be transmitted, the operating speed and the type of misalignment allowed. Check that the hubs fit in the available space and that the keyway matches the one on the shaft. An assembly with the proper fit and careful alignment reduces vibration and extends the life of the assembly.
If you need an equivalent or a nearby size, send us the part number X-13/120 or X-120/120 along with the shaft data: diameter, length and keyway. With that information we can look for the variant that best suits your needs. We can also advise you if the coupling requires an elastic element or if you need only one of the hubs separately.

Frequently Asked Questions
- What is the difference between a normal hub and a solid hub?
- The normal hub and the solid hub are two different configurations of the part. The solid one usually has greater mass and rigidity, while the normal one follows a different construction design. To know which one corresponds to your equipment, compare the original part or consult the manufacturer's data sheet.
- Is the X-13/120 coupling the same as the X-120/120?
- Yes, it is listed as equivalent. The part number X-13/120 corresponds to X-120/120, so when ordering it you can mention either designation so that we identify the same item.
- How do I request a nearby size or an equivalent?
- Send the coupling part number and the shaft data by WhatsApp: diameter, length and keyway. With that we review the X series and offer you the closest variant for a quote.
