This elastic band is the flexible element that fits inside the RUADIGON X-14/140 coupling, a unit also coded X-140/140. Its job is to carry torque from one shaft to the other while letting the assembly tolerate a degree of misalignment and softening the torsional pulses that would otherwise reach bearings, gears and frames. Because it works as a wear item, it is replaced on a schedule rather than repaired. We supply it as a spare for existing equipment, so you can keep the coupling in service instead of swapping the whole unit.

The band is not a complete coupling. It is the insert that sits in the coupling body and, through its shape and compound, transfers motion between shafts with a certain amount of give built in. When the original band ages, stiffens or loses its spring, this is the part that comes out and the new one that goes in. In commercial terms the item is listed as X-14/140, and the X-140/140 reference points to the same piece.

You will find this type of insert on centrifugal pumps, fans, compressors, conveyors, mixers and machine tools, among other driven equipment. The task is always the same: link two shafts while accepting some angular, radial or axial offset, and act as a filter for torsional vibration that would otherwise travel into bearings and structural members. It also helps keep noise down and absorbs small movements caused by temperature changes.

Reading the code correctly is the first step in selecting the right band. Look at the coupling nameplate or the equipment manual and match the designation shown there. X-14/140 is the number to confirm; X-140/140 is the alternate marking you may find on the same machine. During installation, wipe the hub faces and check for burrs, seat the band without forcing it, and keep shaft alignment inside the range the coupling permits. An insert that is worn or fitted off-center wears the rest of the assembly faster.

If you are not sure the X-14/140 is the one you need, send the full coupling code, a photo of the part and the housing dimensions. With that information we can confirm the match or point you to another variant in the X series. We can also check whether a coupling from a different maker is dimensionally compatible with this band.
