The RUADIGON X-4 coupling, catalogued interchangeably as X-35, is a shaft-to-shaft torque transmission element built with solid hubs. It connects two rotating shafts while compensating for small alignment deviations and reducing vibration in the drive train. Maintenance and purchasing teams specify it wherever a dependable mechanical link is required.

Each solid hub is a one-piece body that slides onto the shaft end. Because there is no longitudinal slot, the hub is fitted by pushing it onto the shaft rather than clamping it around it. Paired with the flexible or rigid element of the design, the hubs complete the torque path between the driving and driven sides. The X-4 and X-35 references both appear in RUADIGON documentation for this item, which belongs to the X series of couplings.

Rotating equipment such as centrifugal pumps, fans, compressors, conveyor drives and mills commonly uses this style of coupling with solid hubs. It suits installations that call for a mechanical joint able to carry moderate to high torque while absorbing limited angular or radial offset, staying inside the manufacturer's limits. Gearboxes and machine tools also rely on it where precise, long-lasting transmission matters.

Proper selection starts with the shaft diameters on both sides, followed by torque demand, operating speed and the misalignment the drive is expected to see. Confirm that the solid hubs match the shaft dimensions and that the coupling suits the surrounding conditions, including temperature and exposure to dust or moisture. During mounting, use the correct tooling and align the shafts carefully; poor alignment leads to vibration and early wear.

If you are working from an equivalent reference, quote the part number X-4 or X-35 and we will help you match it. Guidance is available for choosing within the same X series or from other RUADIGON lines, based on the specifications of your equipment. Share the shaft data and working conditions and the selection becomes straightforward.
