The RUADIGON X-13/90 coupling is a rigid, detachable shaft connection made up of a solid hub with screws. It carries no flexible insert, so motion is transmitted directly through metal. The same component is also referenced under the code X-120/90. MR supplies this coupling as part of its power transmission line and can help you confirm it matches your application.

This item is the solid hub with screws for the RUADIGON coupling model X-13/90, which the brand also lists as X-120/90. The hub mounts on the shaft and is secured with screws. Because the design is solid, there is no elastomeric element between the two halves—the drive path is entirely metallic. When replacing a part, compare the code on the existing hub before ordering.

Typical installations include pumps, gearboxes, agitators and other process equipment with aligned shafts, where a firm connection is required and misalignment or vibration absorption is not part of the design intent. The screwed fastening also suits assemblies that are opened frequently for maintenance, since the hub can be removed without cutting or modifying the shaft. Plants that already have this coupling model specified will find it a straightforward replacement.

Correct selection starts with matching the hub bore to the shaft diameter and length. Inspect the screws for wear or damage and tighten them properly during reassembly. Because there is no flexible element, any shaft misalignment is transferred as load to bearings and seals, so alignment deserves attention. Before remounting, check the hub for cracks or deformation around the screw area.

To identify the right part, send a photo of the coupling and the designation marked on it.
