Metal Disc Couplings Metal Disc Couplings SERVOFLEX Max. rated torque [N∙m] Bore ranges [mm] Operating temperature [℃ ] Drive Ultra-high stiffness Low inertia High response No backlash 8000 φ3 ～ 115 －30 ～ 120 100） （ Servomotor/stepper motor Machine tool / semiconductor manufacturing equipment / printing press / packing machine High-stiffness and Low-inertia Servomotor Couplings Metal disc couplings developed for high-speed and high-precision positioning and ultra-precise control of servomotors, etc. While achieving high stiffness, high torque, low inertia, and high response speed, these couplings are also flexible in the torsional direction, in the uneven directions, and in the shaft direction, and are totally free from backlash. Models with various characteristics are available, and each model has a single element type that emphasizes stiffness and a double element type that emphasizes fle

Metal Disc Couplings Customization Cases ■ SFC Model　with slit plate The all-stainless-steel construction provides even better A slit plate is mounted between the hubs to allow it to be used with position detection sensors such as an encoder and photo sensor. ■ SFC Model　with long spacer ■ SFF Model　For non-excitation brake assemblies This is a specification for when the mounting distance The device design can be made more compact by forming between shafts is long. It can be used in applications such the spline to the outer diameter of the SFF model and using as synchronization of gantry...

What are the durability and aging deterioration of the SERVOFLEX? We conduct a torsional durability test by applying a load Static stiffness after the durability test Initial static stiffness larger than the rated torque. SERVOFLEX passed the test by After 10 million cycles withstanding the metal fatigue limit of 10 million cycles of torque with high precision for a long period of time. the deterioration is extremely slow, and it is able to transmit SPEED CHANGERS & REDUCERS INVERTERS repeated load.
