What is a RUPEX coupling?

RUPEX is a fail-safe pin-and-bush coupling series by FLENDER for heavy industrial drives. Steel pins fixed in one hub carry resilient rubber bushes (buffers) that sit in bores of the other hub; torque is transmitted through the elastic bushes, which damp shocks and compensate misalignment. Hubs are available in grey cast iron (type RWN) or steel (type RWS), and versions with brake discs or brake drums are offered for crane and conveyor drives.
