Kev sib txhuam coefficient ntawm cov kabmob dov yog me dua li ntawm cov kabmob zawv zawg, thiab kev sib kis tau zoo yog siab. Feem ntau, qhov kev sib txhuam coefficient ntawm zawv zawg bearings yog {{0}}}08-0.12, thaum cov bearings tsuas yog 0.001-0.005;
2. Rolling bearings tau tiav standardization, serialization thiab generalization, yog haum rau loj ntau lawm thiab muab, thiab yog heev yooj yim mus use thiab tswj;
3. Rolling bearings yog ua los ntawm cov kabmob steel thiab tau txais kev kho cua sov. Yog li ntawd, dov bearings tsis tsuas yog muaj cov cuab yeej siv siab thiab lub neej ua haujlwm ntev, tab sis kuj tuaj yeem txuag tau cov hlau tsis muaj hlau siv hauv kev tsim cov zawv zawg bearings;
4. Qhov kev tshem tawm sab hauv ntawm cov kabmob dov yog me me, thiab kev ua tiav ntawm txhua qhov yog siab, yog li kev khiav haujlwm siab yog siab. Nyob rau tib lub sijhawm, rigidity ntawm cov kabmob tuaj yeem nce ntxiv los ntawm kev thauj khoom ua ntej. Qhov no tseem ceeb heev rau precision machinery;
5. Qee qhov dov bearings tuaj yeem dais radial load thiab axial load tib lub sijhawm, yog li cov qauv ntawm cov kabmob txhawb nqa tuaj yeem yooj yim;
6. Vim muaj kev sib kis tau zoo thiab tsis tshua muaj hluav taws xob tsim ntawm dov bearings, kev noj cov roj lubricating tuaj yeem txo qis, thiab kev tu lub lubrication kuj yooj yim;
7. Rolling bearings tuaj yeem siv tau yooj yim rau cov ncej hauv txhua qhov kev taw qhia hauv qhov chaw.
