    Lub precision ntawm bearing muaj precision thiab rotating accuaracy dimension precision yog ib qhov project uas mount rau shafts, nws muaj xws li nyob rau hauv txoj kab uas hla, sab nraud txoj kab uas hla, dav, chamfer loj kam rau ua los yog tso cai tus nqi.Geometric raug suav nrog txoj kab uas hla sib txawv, nruab nrab sab hauv txoj kab uas hla sib txawv, tawm sab kab. sib txawv, qhov nruab nrab txoj kab uas hla lub nplhaib dav sib txawv hauv ib lub dav hlau radial.rotation qhov tseeb yog rotating Pendulum, nrog rau sab hauv Lub nplhaib thiab lub nplhaib sab nraud radial viav vias thiab lub axial runout, Sab ntawm lub nplhaib puab thiab sab hauv txoj kab uas hla ntawm qhov perpendicularity kam rau ua ntau yam.Bearing precision qib los ntawm qib 0 txog 6, 5, qib 4 thiab qib 2, nyob rau hauv lem, hauv qab no yog lub rooj sib piv ntawm preeision chav kawm ntawm Tuam Tshoj GB 307 thiab lwm yam precision standard.Giant bearing precision qib yog los ntawm qib 6, 5, 4 thiab 2 qib ntawm plaub qib. 

    Lub nplhaib sab nrauv 11, lub nplhaib sab hauv 12, thiab lub pob 13 uas yog cov kabmob yog 0.95 pawg% lossis ntau dua thiab 1.10 pawg% lossis tsawg dua carbon, 0.05 pawg% lossis ntau dua thiab tsawg dua 0.3 pawg% silicon, 0.10 pawg% lossis ntau dua thiab 0.50 huab hwm coj% 11 A ntawm lub nplhaib sab nrauv raceways thiab 12 A ntawm sab hauv lub nplhaib raceways uas yog cov saum npoo uas muaj cov hlau uas muaj cov manganese hauv qab no, 1.30 pawg% lossis ntau dua, thiab 2.00 pawg% lossis tsawg dua, thiab muaj cov hlau uas muaj cov hlau seem thiab cov impurity, thiab kev sib cuag nrog lwm cov khoom. Thiab qhov nruab nrab nitrogen concentration nyob rau hauv cov txheej txheej saum npoo ntawm thaj tsam 11B, 12B, thiab 13B uas yog thaj chaw hauv qhov tob ntawm 20 μm los ntawm lub pob dov nto 13A yog 0.2% los ntawm huab hwm coj lossis ntau dua thiab 0.7% los ntawm huab hwm coj lossis tsawg dua, thiab hauv qhov chaw. cov cheeb tsam txheej 11B, 12B, 13B, 5 lossis ntau dua carbides nrog txoj kab uas hla ntawm 0.5 micrometer lossis tsawg dua nyob rau ib 100 micrometer.
