Li cas pob bearings tau ua
Kev tsim khoom lag luam rau cov kabmob pob khoom yog sib tov ntawm precision engineering thiab lub sijhawm ntsuas lub sijhawm {}}
Nws txhua tus pib nrog xaiv cov khoom siv raw, feem ntau yog cov txheej txheem txias rau hauv nws, tab sis nrog lub nplhaib sib tw txias ib puag ncig nws, hu ua "burrs," uas ua rau nws zoo li lub Ntiaj Teb Saturn .
Tom ntej no, cov pob tau pub rau hauv lub tshuab nruab nrog cov pob loj, hu ua "ib lub ntsej muag muaj nyob hauv ib txoj kab sib dhos burrs tau maj mam muab tshem tawm, muab cov khoom ntim ntau dua li cov hlau, ua kom lub ntsej muag zoo nkauj dua cov khoom thiab cov phiaj xwm ua rau cov cua sov {}}
Tom qab thawj zaug ua kom zoo li cas, cov khoom tuaj yeem yuav tsum tau kho tshav kub {}} Cov pob txha no ua kom tiav (thiab ua kom cov pob zeb no tseem yuav tsum tau ua kom tiav)} kawg qhov ntev .
Thaum kawg, cov npas yog av . cov txheej txheem sib tsoo siv cov khoom sib tsoo uas siv cov khoom sib tsoo uas siv cov khoom siv du-precision machinery {}}
