The RUADIGON X-4 coupling is a power transmission component used to join two shafts and transmit motion between them. In this case it is the plain hub with screws, the part that is mounted on the shaft and secured by screws, and which is equivalent to model X-35. It is a practical solution for replacements and assemblies where a removable and reliable connection is needed.
This item is the plain hub with screws of the RUADIGON X-4 coupling, which is equivalent to model X-35. The hub is the part that is fitted onto the shaft and secured with screws, which allows the transmission to be assembled and disassembled without the need for presses or permanent adjustments. It is a replacement part designed to keep the coupling in service when the original hub wears out or is damaged.
It is used in power transmission lines where shafts must be connected and small misalignments absorbed. It appears in conveying equipment, mixers, pumps, fans and machines in general that work with continuous rotary motion. It is also common in industrial maintenance, where hubs and screws are replaced to restore the coupling without changing the entire assembly.
To mount the hub, verify that the shaft diameter and the hub bore match, and that the screws are in good condition and at the proper torque. Check that the bearing faces are clean and free of burrs. If the coupling works with misalignment, it is advisable to align the shafts before tightening the screws to avoid vibrations and premature wear.
If you need an equivalent or a nearby size, send us the part number of the coupling or of the hub you are replacing. With that data we can look for the compatible part within the RUADIGON line or suggest an alternative. A photo of the part and the shaft measurement also works, so we can confirm properly before quoting.
At MR Accesorios Industriales we carry the RUADIGON line and can advise you so that the replacement is the correct one. Send the part number X-4 or X-35 by WhatsApp and we'll send you the quote with the data you need for your equipment.
