These are pin-bushing type couplings whose body is made of aluminum alloy. Backlash is kept extremely low by combining high-precision pins with dry metal.The compact design limits total length and the angle of deflection allowed is 1°. 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.
Friction damping effect
There is a damping effect from sliding at the frictional surface of the pin and metal bush.
Extremely small shaft reaction force
The reaction force caused by mounting error is extremely small thanks to the pin/metal bush construction.
