O-rings yog haum rau siv nyob rau hauv ntau yam khoom siv kho tshuab, muab kev sib khi ua haujlwm raws li qhov ntsuas kub, qhov siab, thiab cov kua thiab roj sib txawv, txawm tias nyob ruaj ruaj lossis hauv kev txav mus los. Lawv tau siv dav hauv cov cuab yeej siv tshuab, nkoj, tsheb, khoom siv aerospace, metallurgical machinery, tshuaj machinery, engineering machinery, siv machinery, mining machinery, roj av machinery, plastics machinery, agricultural machinery, thiab ntau yam twj paj nruag thiab meters.
O-rings feem ntau yog siv rau qhov zoo li qub thiab sib txuas lus sib txuas. Thaum siv rau kev sib txuas lus sib txuas, lawv raug txwv rau qis -ceev rotary sealing li. O-rings feem ntau yog ntsia rau hauv lub voj voos ntawm sab nrauv lossis sab hauv ntawm lub nplhaib rau kev sib khi. O-rings tuav zoo sealing thiab vibration damping zog txawm nyob rau hauv ib puag ncig tiv taus roj, acids, alkalis, puas, thiab tshuaj corrosion. Yog li ntawd, O-rings yog ib qho ntawm feem ntau siv sealing Cheebtsam hauv hydraulic thiab pneumatic kis tau tus mob.
