The RUADIGON X-4 coupling is a power transmission component equivalent to the X-35 model. It is a solid hub with screws, designed to join shafts and transmit torque in industrial equipment. Its solid design and screw fastening system allow firm and removable assembly, ideal for maintenance and replacements in plant. MR Accesorios Industriales carries this line as part of its offering in couplings and transmission accessories.

This item is the solid hub with screws of the RUADIGON X-4 coupling, which is equivalent to the X-35 model. The hub is the central part that mounts on the shaft and receives the torque; being solid, it has no housing for an elastic element, so it is used in rigid configurations or as part of an assembly built with other components. The screws allow the hub to be fastened and removed without hydraulic presses or special tools. The X-4 designation and its X-35 equivalence are the data you must use to identify the spare part.

Typical applications of a solid hub with screws include couplings between motor and gearbox, low and medium speed transmissions, and equipment where a removable joint with good concentricity is needed. It is also used in plant machinery such as conveyor belts, mixers, pumps and industrial fans. Since it has no flexible element, it requires careful alignment between shafts to avoid parasitic loads on bearings and seals. It is a common maintenance part in scheduled replacements.

To select and mount this hub, first check the shaft diameter and the type of keyway, data that is confirmed against the manufacturer's product page. Check angular and radial alignment before tightening the screws: a misalignment greater than the allowable value accelerates wear on the equipment's bearings. Apply the tightening torque in a cross and progressive pattern. If the coupling works with rotation reversal or pulsating loads, periodically check the screw tightness and the condition of the contact surfaces.

If you need an equivalent or a nearby size, send us the complete part number shown on the part or on the drawing. With the X-4 model, the X-35 equivalence and the component (solid hub with screws) we can look for the option that best fits your equipment. We can also guide you if the original coupling came assembled with another configuration. The more data you send us — shaft diameter, type of fastening, number of screws — the more accurate the proposal will be.
