Txheem pob bearings steel nrog cov ntsiab lus ntawm cov pa roj carbon thiab chromium raug xaiv thiab hardended los tiv thaiv lub siab hnyav ntawm cov khoom dov thiab cov kabmob rings.
Carbonitriding ntawm ob sab hauv thiab sab nrauv yog txheej txheem nyuaj rau ntau tus neeg muag khoom TPI pob bearings. Los ntawm qhov kev kho cua sov tshwj xeeb no, hardness ntawm raceway nto yog nce; uas txo qhov hnav kom haum.
Ultra-ntxuav hlau yog muaj nyob rau hauv qee yam ntawm TPI tus qauv pob bearings 'cov khoom lag luam tam sim no, kev hnav-tiv taus ntau dua tau txais raws li. Txij li thaum kev sib cuag qaug zog feem ntau tshwm sim los ntawm cov khoom siv tsis yog hlau, cov bearings niaj hnub no yuav tsum muaj qhov tshwj xeeb ntawm kev huv.
