Summary of the Meaning of FAG Bearing Suffixes

FAG's bearing code muaj cov lej yooj yim, cov lej ua ntej thiab cov lej tom qab. Cov cai yooj yim qhia txog hom qauv qauv thiab qhov loj ntawm cov kabmob. Lub prefix code qhia tias cov kabmob qhov chaw yog muab tso ua ntej lub hauv paus code. Cov lus xaus qhia tau hais tias tus lej ntxiv yog ntxiv tom qab tus lej lej ntawm cov kabmob thaum muaj kev hloov pauv ntawm cov kabmob qauv, qhov loj, foob, tawb, kam rau ua, tshem tawm, kho cua sov, ntim, kev xav tau, thiab lwm yam.
