Coupling description

ROTEX® GS is a three-part, axial plug-in coupling backlash-free under pre-stress. In spite of its vibration-damping characteristics it is torsionally stiff so that it is not necessary to make any concessions to accuracy even with highly dynamic servo drives. ROTEX® GS is available in different types of hubs which can be combined within one coupling size.
