Spring washer couplings enable backlash-free angularly aligned transmission of rotary movements. Very high torsional stiffness, low restoring forces. Extremely robust stainless steel spring washers. Good compensation of all misalignment, vibration damping. Tried-and-tested transmission element, also for critical applications. Long service live, maintenance-free, noiseless operation. Mounting with adjusting screw or clamping flange.
