The RUADIGON X-13/90 coupling is a power transmission component consisting of a solid hub with screws, designed to connect two shafts and transmit motion without intermediate flexible parts. It is used in equipment where a rigid and detachable connection is needed, and its commercial designation also appears as X-120/90. At MR Accesorios Industriales we handle it as part of the line of couplings we carry, and we help you verify that it is the part that goes on your machine.

This item is the solid hub with screws of the RUADIGON coupling model X-13/90, which the brand also references as X-120/90. The hub is the part that is mounted on the shaft and fastened by means of screws, and since it is solid it has no flexible insert: the connection is metallic and direct. The assembly is identified by that designation and by the component indicated, so if your equipment has a hub of this type, it is advisable to compare the code before replacing it.

It is used in machines where the transmission must be firm and where absorbing misalignment or vibrations is not sought, such as pumps, gearboxes, agitators or process equipment with aligned shafts. It also appears in assemblies where the coupling is assembled and disassembled frequently for maintenance, because fastening by screws allows the hub to be removed without cutting the shaft. It is a common replacement part in plants that already have the coupling model defined for their equipment.

To choose it correctly, verify that the shaft diameter and length match the hub bore, and that the screws are in good condition and correctly tightened. Alignment between shafts is key: since there is no flexible element, any misalignment is transmitted as stress to the bearings and seals. Also check that the hub has no cracks or deformations in the screw area before remounting it.
