Siemens Rupex Pin & Bush Couplings

RUPEX couplings are used as flexible compensating couplings in all applications requiring a reliable transmission of torque under harsh operating conditions. The conical seats of the buffer pins facilitate mounting and guarantee maintenance-free operation.

The optimised shape of the barrelled buffers allows simple plug-in assembly and low circumferential backlash. Many type variants are offered, e. g. with brake disk, axial play limiting device, or brake motor couplings.
