Lub npe hu ua precision bearings xa mus rau kev faib tawm raws li ISO kev faib tawm: P0, P6, P5, P4, P2.Cov qhab nia tau nce zuj zus, ntawm qhov P0 yog qhov zoo tib yam, thiab lwm qib yog qib precision.Ordinary bearings yog peb cov kabmob uas nquag siv.Dab tsi yog qhov txawv ntawm precision bearings thiab dog dig bearings?Raws li kev nkag siab ntxaws, peb yuav qhia qhov sib txawv ntawm precision bearings thiab dog dig bearings.

Dab tsi yog qhov txawv ntawm precision bearings thiab dog dig bearings?

Lub precision bearing yog txawv ntawm cov kabmob zoo tib yam.1. Qhov yuav tsum tau muaj qhov sib txawv.Qhov sib txawv ntawm qhov sib txawv (sab hauv txoj kab uas hla, sab nraud txoj kab uas hla, ellipse, thiab lwm yam) ntawm cov khoom nrog qib siab precision yog me dua li tus nqi uas yuav tsum tau ua los ntawm cov khoom nrog qib qis dua;

Lub precision bearing yog txawv ntawm cov kabmob zoo tib yam.2. Qhov yuav tsum tau muaj ntawm qhov kev sib hloov qhov tseeb yog qhov sib txawv.Cov khoom uas muaj siab precision muaj siab dua qhov tseeb ( puab radial runout, sab nraud radial runout, kawg lub ntsej muag rau raceway runout, thiab lwm yam) dua li cov khoom uas qis precision qib.Tus nqi yuav tsum yog nruj;

Lub precision bearing yog txawv ntawm cov kabmob zoo tib yam.3. Cov duab saum npoo thiab qhov chaw zoo sib txawv.Qhov saum npoo thiab qhov zoo ntawm cov khoom nrog qib siab precision (nto roughness, ncig sib txawv, groove deviation, thiab lwm yam. ntawm raceway los yog channel) Cov khoom uas qis dua qhov raug theem yuav tsum nruj dua qhov tseem ceeb;

Precision bearings txawv ntawm cov bearings zoo tib yam.4. Cov khoom lag luam nrog cov qib siab precision tshwj xeeb yog qhov zoo dua li cov qib siab dav dav.

Nyob rau hauv tus txheej txheem ntawm kev siv cov kabmob, qhov precision bearing lossis cov kabmob zoo tib yam raug xaiv raws li cov kev cai tshwj xeeb, kom cov cuab yeej siv tshuab lossis cov khoom siv tau zoo dua.
