Covbearingyog kev txhawb nqa ntawm lub tshuab tsav ncej, qhov tseem ceeb lav rau kev ua haujlwm, kev ua haujlwm thiab kev ua haujlwm ntawm lub tshuab tseem ceeb, thiab hu ua "sib koom" ntawm cov tshuab thiab khoom siv. Nws lub luag haujlwm tseem ceeb yog hloov lub zog thiab txav thiab txo qis kev sib txhuam.
Tuam Tshoj yog ib qho ntawm plaub kev vam meej thaum ub. Tuam Tshoj cov thev naus laus zis thaum ub tau ci ntsa iab heev, thiab plaub qhov kev tsim khoom muaj txiaj ntsig zoo rau cov tiam tom ntej. Tuam Tshoj kuj yog lub teb chaws uas pib tsim thiab tsim cov bearings. Thaum ntxov li ntau tshaj 4,000 xyoo dhau los, tsheb tau tshwm sim hauv Suav teb thiab pib siv zawv zawg bearings. Thaum lub sijhawm Zhou Dynasty, kev siv tsiaj roj rau cov kabmob lubrication tshuab tau tsim. Thaum lub sijhawm Warring States, Tuam Tshoj maj mam pib ua cov vuas ncej nrog hlau. Guo Shoujing, tus kws tshawb fawb hauv Yuan Dynasty, tau tsim cov kev txhawb nqa teb (turntable bearing) thev naus laus zis. Nyob rau hauv Qing Dynasty, cylindrical cov menyuam bearings tau ua nyob rau hauv ib tug niaj hnub bearing qauv. Thaum lub sij hawm lub koom pheej ntawm Tuam Tshoj, Tuam Tshoj maj mam pib loj ntau lawm thiab ua cov bearings, thiab tsim Wafangdian, Shanghai ob bearing ntau lawm thiab manufacturing puag. Tom qab nrhiav tau ntawm Tuam Tshoj 's koom pheej ntawm Tuam Tshoj, Tuam Tshoj's bearing kev lag luam tau tsim sai heev, thiab thaum kawg nteg tag nrho cov qauv ntawm tam sim no.kev loj hlob ntawm kev lag luam bearing. Txawm hais tias Tuam Tshoj twb dhau los ua tus thib peb loj tshaj plaws bearing ntau lawm thiab muag lub teb chaws nyob rau hauv lub ntiaj teb no.

Nrog rau txoj kev loj hlob sai thiab tshiab technologies xws li aerospace, nuclear kev lag luam, electronics computer, kho qhov muag thiab electromagnetic instruments, thiab precision machinery, lub ntiaj teb no bearing kev lag luam qhia txog theem tam sim no ntawm science thiab technology tau nkag mus rau ib tug tshiab era ntawm tag nrho innovation ntawm ntau lawm. thev naus laus zis, kev tsim kho sai sai, txhawb kev ua tau zoo, ua kom zoo, thiab ua kom paub tab thiab zoo meej.
Nrog rau kev nce qib ntawm Tuam Tshoj txoj kev lag luam thiab kev txhim kho tas mus li ntawm automation, cov kev xav tau rau tus tswv tsev yuav nce siab thiab siab dua, thiab tom qab ntawd cov kev ua tau zoo thiab cov qauv txheej txheem ntawm pab pawg bearing yuav siab dua thiab siab dua, cov khoom tshiab txuas ntxiv mus, qhov kev thov. yuav inevitably yuav loj thiab loj.
Lub xeev txuas ntxiv ua kom muaj zog txuag hluav taws xob thiab txo qis kev siv zog thiab tsim kom muaj lub zog txuag hluav taws xob yuav muaj tseeb ua kom cov txheej txheem hloov pauv ntawm kev txuag hluav taws xob thiab kev txo qis ntawm kev lag luam ib txwm muaj. Tsis tas li ntawd, kev txhawb nqa kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab yuav ua rau muaj kev vam meej ntau dua rau kev nce qib ntawm kev lag luambearing kev lag luam. Yog li ntawd, kev lag luam bearing tseem yuav loj hlob sai sai yav tom ntej.
