Description
RUADIGON X-8 · Banda elástica belongs to coupling, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for X-8 · Banda elástica and any equivalents.
The elastic band is the flexing element of the RUADIGON X-8 coupling, the part that carries torque from one hub to the other while letting the assembly tolerate a degree of angular and radial offset. It also serves as the replacement band for couplings designated X-70. Buyers typically order it to bring a worn coupling back to its working condition rather than to replace the whole unit.
The commercial designation is X-8 · Elastic band. In service, the band sits between the two hubs and is the only component that flexes, so it takes the movement that the shafts cannot absorb on their own. Once it hardens, cracks or deforms permanently, the coupling loses that flexibility and the transmission starts to run rough.
Couplings of this type appear on centrifugal pumps, fans, compressors, conveyors and machine tools, and also on drives that start and stop often, where torque spikes have to be absorbed. Damping vibration and covering small alignment errors is what keeps the connected bearings and the surrounding equipment out of trouble.
Before ordering, confirm that the coupling on the machine is an X-8 or its X-70 equivalent. At assembly, the band should seat without being forced and without excess clearance, since either condition shortens its life. Shaft alignment should be checked at the same time, and the hub faces should be free of burrs or wear, as rough surfaces will damage a new band. Periodic inspection for cracking or permanent deformation tells you when to replace it.
If you are looking for an alternative, send the code X-8 · Elastic band or the coupling model. We can review options within the RUADIGON line and among the other brands we supply, confirming that dimensions and function match your application. If the designation on your equipment is unclear, ask and we will help you identify it.
Quotes are handled by WhatsApp or email. Include the code X-8 · Elastic band and we will reply with what you need to place the order. Coupling and power transmission parts outside this line can be quoted the same way.

Frequently asked questions
- Does the X-8 elastic band also fit the X-70 coupling?
- Yes. X-70 is the equivalent designation, and the X-8 band is the flexing part for that coupling. If you are unsure which model you have, send us the coupling code and we will confirm.
- What tells me the elastic band needs replacing?
- Look for cracks, permanent deformation, hardening or uneven wear on the band. Unusual vibration or noise from the transmission is another sign. Keeping the shafts aligned during assembly helps the band last longer.
- Which details should I send when asking for an equivalent band?
- Give us the coupling model (X-8 or X-70), the brand, and if possible a photo or sketch with the housing dimensions. With that we can check a compatible option or confirm the part. WhatsApp is the quickest way to reach us.
