USI itha kugwiritsidwa ntchito posindikiza pisitoni ndi ndodo.Kupaka uku kuli ndi kagawo kakang'ono ndipo kamakhala koyikidwa mumsewu wophatikizika.
YA ndi chosindikizira cha milomo chomwe chitha kugwiritsidwa ntchito pa ndodo ndi pisitoni, ndichoyenera mitundu yonse ya masilinda amafuta, monga ma silinda opangira ma hydraulic cylinders, masilinda agalimoto zaulimi.
Mtundu wa UPH chisindikizo umagwiritsidwa ntchito posindikiza pisitoni ndi ndodo.Mtundu uwu wa chisindikizo uli ndi gawo lalikulu la mtanda ndipo ungagwiritsidwe ntchito pazinthu zosiyanasiyana.Zida za mphira za Nitrile zimatsimikizira kutentha kwakukulu kogwiritsira ntchito ndi ntchito zosiyanasiyana.
Pokhala atagwiritsidwa ntchito kwambiri mu masilinda a hydraulic, USH itha kugwiritsidwa ntchito popangira pisitoni ndi ndodo chifukwa chokhala ndi kutalika kofanana kwa milomo yonse yosindikiza.Yokhazikika ndi zinthu za NBR 85 Shore A, USH ili ndi zinthu zina zomwe ndi Viton/FKM.
UNS/UN Piston Rod Seal ili ndi gawo lalikulu ndipo ndi mphete yosindikizira yooneka ngati asymmetrical yokhala ndi kutalika kofanana kwa milomo yamkati ndi yakunja.Ndizosavuta kulowa mumtundu wa monolithic.Chifukwa cha gawo lalikulu, UNS Piston Rod Seal nthawi zambiri imagwiritsidwa ntchito mu silinda ya hydraulic yokhala ndi pressure yochepa. Popeza imagwiritsidwa ntchito kwambiri mu masilindala a hydraulic, UNS imatha kugwiritsidwa ntchito popangira pisitoni ndi ndodo chifukwa chokhala ndi kutalika kwa milomo yonse yosindikiza. ofanana.
