Siemens RUPEX couplings serve as adaptable compensating couplings in applications that demand dependable torque transmission in challenging operating environments.

The buffer pins have conical seats. This simplifies mounting while also eliminating the need for maintenance. The barrelled buffers with an optimal design enable easy plug-in assembly and keep the circumferential backlash constantly low.

The couplings are available in many variants, such as with brake motor couplings, for limiting the axial play, or with brake disk.
