1. Qhov tseeb qhov ntev: Precision bearings yuav tsum muaj qhov ntev raws li lawv yuav tsum tau ua kom haum rau cov duab geometric ntawm lub tshuab mating.
2. Qhov zoo ntawm qhov chaw: qhov zoo ntawm qhov chaw mating yog qhov tseem ceeb vim tias cov kabmob precision yuav tsum hu rau saum npoo ntawm mating qhov chaw thaum tig, yog tias qhov zoo ntawm qhov chaw tsis zoo, nws yuav ua rau muaj kev sib txhuam ntxiv, kev sib txhuam me ntsis yuav hnav lub load. hu rau saum npoo thiab ua rau lub neej luv luv.
3. Khoom siv: Lub tshuab mating yuav tsum tau ua los ntawm cov khoom siv tib yam los yog sib xws raws li cov kabmob precision. Thaum xaiv mating tshuab qhov chaw, xyuas kom meej tias lawv cov khoom muaj lub zog txaus thiab hnav tsis kam, txwv tsis pub cov kev sib txhuam ntawm cov kabmob thiab cov tshuab yuav ua rau hnav.
4. Cov txheej txheem zoo: Cov mating qhov chaw yuav tsum tau tsim los siv cov txheej txheem tsim nyog. Rau precision bearings, lub hom phiaj zoo ntawm cov txheej txheem tsim khoom yog tsim kom muaj qhov ntev, tsis muaj qhov pom tseeb ntawm qhov tawg thiab cov khoom sib xws ntawm lub tshuab qhov chaw.
5. Kub: Qhov kub ntawm cov mating qhov chaw yuav tsum sib phim rau cov kabmob, vim tias thermal expansion thiab contraction tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov kabmob precision, thiab cov teebmeem ntawm qhov kub thiab txias tuaj yeem txo qis los ntawm kev xaiv ntawm mating qhov chaw.
