Paraflex

These are pin-bushing type couplings whose bodies are made of aluminum alloy. Backlash is kept extremely low by making the torsional stiffness of all components very high and combining high-precision pins with dry metal. A universal system is used for hub coupling, which makes shaft reaction force due to mounting misalignment extremely small. There is also a damping effect from sliding at the friction surface between the pin and dry metal. A clamp system employing friction is used to mount the coupling on the shaft, making mounting easy. PARAFLEX comes in both CPU models that allow angles of deflection up to 4°and inexpensive CPE models that allow angles of deflection up to 1°.
