Features

・Anti-misalignment, multi-purpose.
・Two types of plate materials to suit all applications.
・Polyimide - due to its superb flexibility, it has a low reaction force, phase error and torque fluctuations, even when misaligned.
・Carbon FRP - multi-purpose type, with good balance of characteristics, offering high levels of flexibility, transmission torque, and torsional rigidity.		 ms 01

・Heat resistance(ambient temperature): polyimide:-40℃ to 200℃, carbon FRP:-25℃ to85℃ *1/2 the allowable torque should be used at maximum temperature.
・Maximum torque is basically twice as large as allowable torque. When selecting size, please note that applied torque must be equal to or less than the given value for allowable torque, and its instantaneous maximum load torque must be equal to or less than the given value for maximum torque.
