I-UNS/UN Piston Rod Seal ine-cross-section ebanzi futhi iyindandatho yokuvala emise okwe-u e-asymmetric enobude obufanayo bezindebe zangaphakathi nezingaphandle.Kulula ukungena esakhiweni se-monolithic.Ngenxa yobubanzi be-cross-section, i-UNS Piston Rod Seal ngokuvamile isetshenziswa kusilinda samanzi esinengcindezi ephansi. Njengoba isisetshenziswe kakhulu kumasilinda adonsa amanzi, i-UNS ingasetshenziselwa ukufaka i-piston nenduku ngenxa yobude bazo zombili izindebe ezivalayo. kulingana.
