About the FLEXXOR Coupling
The FLEXXOR is a diaphragm flexible shaft coupling that has been widely used since the1960’s. It operates by carrying torque through thin spokes between an inner and outer rim, much like a bicycle wheel. Paired with Anderson Keyless Clamp Hubs, they can be installed on straight or tapered shafts in only a few minutes, yet carry tremendous amounts of torque. The FLEXXOR is an excellent solution for high-speed applications and situations with significant axial and/or angular misalignment. For applications with short shaft-to-shaft spacing or where reduced moments are needed, see our page on Close Coupled and Reduced Moment Couplings. View Page
FLEXXOR Coupling In Action
Extreme Flexibility in High-Speed, High-Torque Applications
The exclusive holed diaphragm design that sets the standard for coupling flexibility, the FLEXXOR shaft coupling, is manufactured by Coupling Corporation of America. The FLEXXOR shaft couplings are designed to provide extreme flexibility in high-speed and high-torque applications. The angular and axial spring rates are far lower than any other coFLEXXOR flexible shaft coupling diaphragm couplings in the industry. The FLEXXOR shaft couplings have been consistently the most flexible and durable shaft couplings on the market. Its unique holed diaphragm design allows for several degrees of misalignment while still transmitting the highest torque values. The FLEXXOR diaphragm works like a bicycle wheel. The tension in the “spokes” transmits the torque from inside to outside. The thin, hold-filled diaphragm flexes easily to accept angular and axial misalignment. Power plants, refineries, and large process plants use our FLEXXOR shaft couplings for applications that include high-speed pumps, gas turbines, centrifugal compressors, aircraft applications, and API 671 applications.
FLEXXOR flexible shaft coupling offers complete application flexibility
Factory assembled elements simplify installation of FLEXXOR shaft couplings. There are no loose parts so that FLEXXOR shaft couplings maintain balance. Bolts are delivered in sets and are weight balanced on high speed or API applications.
Unmatched Benefits of the FLEXXOR Flexible Shaft Coupling
| Feature | Value to User |
|---|---|
| Multiple paths of torque transmission share the load | Scratch or other damage to a diaphragm will not destroy coupling. |
| No lubrication or maintenance required | Reduces maintenance cost |
| Very low spring rates | Low forces on shafts, bearings, and seals for longer system life. |
| Dynamically balanced | No coupling related vibrations |
| Internal spin-off protection | Plant safety in case of a machine malfunction. |
| Easy hub adjustment for flange to flange spacing | Faster installation and no hot work permits required. No shim packs required. |
| Spacer or reduced moment designs | Outstanding application flexibility |
