The RUADIGON X-13/120 coupling, also referred to as X-120/120, is a power transmission component consisting of a normal hub and a solid hub. It connects two shafts to transmit motion in industrial machinery, and its design accommodates minor misalignments depending on how it is assembled. MR Industrial Accessories LLC supplies this coupling as part of its power transmission line for maintenance and replacement needs.
This coupling belongs to the RUADIGON X series and is designated X-13/120 or X-120/120. The assembly comprises two parts: a normal hub and a solid hub. It is not a complete flexible coupling with an integrated elastic element; rather, it consists of the hubs that mate with each other. For detailed dimensions, shaft diameters, and tolerances, refer to the manufacturer's data sheet.
Couplings like this are commonly found in transmission lines linking a motor or gearbox to driven equipment. They appear in conveyors, pumps, fans, mixers, and various process machines. The pairing of a normal hub with a solid hub suits setups that require a rigid or semi-rigid shaft connection, depending on the overall design and operating conditions.
When selecting a coupling, consider the shaft diameter and length at each end, the torque to be transmitted, the operating speed, and the type of misalignment permitted. Verify that the hubs fit within the available space and that the keyway matches the shaft. Proper fit and careful alignment during installation help reduce vibration and extend the service life of the assembly.
To request a quote for an equivalent, send the part number X-13/120 or X-120/120 along with shaft details: diameter, length, and keyway. With this information, we can identify the variant that best meets your requirements. We can also advise whether an elastic element is needed or if you require only one of the hubs separately.

Frequently asked questions
- What distinguishes a normal hub from a solid hub?
- The normal hub and solid hub are two different configurations. The solid version typically has greater mass and rigidity, while the normal hub follows a different construction. To determine which one matches your equipment, compare with the original part or consult the manufacturer's data sheet.
- Is the X-13/120 coupling equivalent to the X-120/120?
- Yes, they are listed as equivalent. The part number X-13/120 corresponds to X-120/120, so you can mention either designation when ordering, and we will identify the same item.
- How do I request an equivalent coupling?
- Send the coupling part number and shaft data via WhatsApp or email: diameter, length, and keyway. We will review the X series and offer the appropriate variant for a quote.
