RUPEX Pin and Bush Coupling

Damping, fail-safe pin and bush coupling for medium and higher torques
Nominal torque range from TKN = 200 Nm up to 1,300,000 Nm with 26 sizes
Temperature range: from –50 °C to +100 °C

Robust and proven a million times

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 optimized shape of the barreled 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.
