For drives that link a standard hub to a solid hub, the RUADIGON X-13/90 handles the connection and keeps torque flowing. Its code places it inside the X series, and the same unit is also referenced as X-120/90. Maintenance teams in agricultural and industrial settings use it when a dependable joint between rotating parts is required.

The assembly brings together two hub styles: one standard and one solid, which gives flexibility in how the coupling is mounted. The X-13/90 label identifies this particular variant in the RUADIGON X range, and X-120/90 points to the same item. By joining two shafts or rotating elements, the coupling transfers torque while accommodating a degree of misalignment. Metal construction and the way the hubs seat together support consistent operation in tough working conditions.

You will find this coupling on agricultural equipment such as seeders, harvesters and trailed implements, where power take-off feeds other mechanisms. Conveyors, industrial drives and cardan shaft arrangements also rely on it for a solid link between hubs. Moderate speeds with changing loads are typical in these setups, and the part often appears on preventive and corrective maintenance lists.

Choosing the right unit starts with the hub type you plan to connect, standard or solid. Check that the shaft diameter and spline profile line up with the matching hub, and confirm alignment to reduce vibration and wear. Before mounting, clean the contact surfaces and tighten to the torque figure the manufacturer specifies. When swapping out a similar coupling, compare dimensions and spline count first.
