Qws -} kawg bearingsyog cov tshuab sib xyaw ua ke rau kev sib txuas thiab kev sib kis tau zoo. Lawv cov kev tsim kho cuam tshuam ntau yam tseem ceeb, txhua tus nrog ib qho kev ua haujlwm tshwj xeeb:
1.inner tes tsho: qhov no yog lub nplhaib sab hauv ntawm tus pas nrig {{1} binery tsho tag nrho, feem ntau yog cylindrical encisely engeting enning mus rau pas nrig lossis ncej.
2.outer nplhaib: ua haujlwm raws li kev sib tw sab nraud ntawm cov kabmob, nws yog tsim los ntawm cov khoom siv muaj zog xaiv los ntawm tus ncej.
3. Kuj hu ua cov menyuam roj, cov no tuaj nyob rau ntau hom xws li springes, thooj voos kheej kheej, lossis cones. Lawv lub luag haujlwm tseem ceeb yog txhawm rau pab txhawb nqa cov lus tsa suab los ntawm kev tiv tauj ob qho tib si sab hauv thiab sab nraud, yog li txo kev sib txhuam thiab hnav hauv cov kabmob.
4.Retainer: Qhov sib xyaw no yog qhov tseem ceeb rau kev nyab xeeb lub yob cov ntsiab hauv lawv cov haujlwm kom raug, kom lawv tiv thaiv lawv los ntawm pawg. Hom Retainer hom xws li tawb thiab tawb thiab thau tawb.
Qws -}}}} Thaum kawg kev ua kev zoo siab rau lawv cov virtatility thiab kev ua tau zoo nyob thoob plaws kev lag luam, los ntawm Aerospace kev lag luam.
