Oscillation is a movement similar to joints of the human body. Various parts are joined together and gaps that would otherwise be created by complex movements are smoothly brought together. "Joints" or "couplers" between machine parts are also well known. THK products exhibiting oscillating movements include "Link Balls," "Rod Ends" and "spherical plain bearings". In particular, our high-performance link balls have been manufactured based on our unique technologies since the formation of THK.
