The RADEX

®

-NC servo laminae coupling is a backlash-free, torsionally stiff and flexible steel 

laminae coupling. It has been developed particularly for the ranges of servo technology in 
order to meet the demands of high torsional stiffness (e. g. use in indexing tables, planet and 
worm gear pairs, ball roll spindles etc.).
