The RUADIGON X-3, also referred to as X-30, is a coupling built around a solid hub that is secured with screws. It connects two shafts and carries torque through a bolted fastening arrangement rather than an elastomer element or a disc pack, so it belongs to the rigid side of the RUADIGON X series. MR supplies this model as part of its coupling range.

In practical terms, the X-3 is a hub of solid construction that clamps onto the shaft with screws. That distinguishes it from flexible elastomer couplings and from disc couplings: there is no intermediate elastic or laminated element doing the work, just a bolted joint between hub and shaft. Depending on how the assembly is set up, a small amount of misalignment can still be accommodated.

Machine tools, pumps, fans, conveyor drives and continuous process equipment are the kinds of applications where this model tends to appear. It suits installations that call for a direct shaft-to-shaft connection, reasonable torsional stiffness, and the ability to take the coupling apart without reaching for special tooling. Where the envelope is tight, a compact screw-fastened hub is often the more practical choice than other fastening methods.

When specifying an X-3, work from the shaft diameters being joined, the torque the drive has to carry, the running speed and the nature of the load. Confirm that the solid hub matches the shaft diameter and the available shaft length. During installation, bring the shafts into alignment within the permitted tolerances and tighten the screws as the manufacturer directs. If the equipment runs with vibration or pulsating loads, it is worth checking whether this rigid design is the right fit or whether a flexible coupling would serve better.

If you are looking for an equivalent within the X series, send the exact part number or simply the shaft dimensions. MR can help pin down the variant that matches your application, whether the deciding factor is diameter, fastening style or hub configuration, and can point you to other RUADIGON coupling models when this one does not cover the requirement.
