Bearings yog cov khoom siv thiab cov khoom tseem ceeb hauv cov cuab yeej siv tshuab, thiab kev siv cov bearings kuj yog qhov dav heev. Txhawm rau kom tau nyiaj ntau dua, muaj ntau tus tub lag luam siab dub uas siv cov qub los them rov qab, thiab rov ua dua qee qhov siv lossis tsis siv cov bearings qub los yuav lawv li cov kabmob tshiab tom qab ua tiav. Qhov zoo ntawm cov kabmob refurbished no tseem txawv ntawm cov bearings zoo. Nws tsis yog zoo li ib tug zoo bearing. Raws li kev paub txog kev paub txog kabmob, Tuam Tshoj Bearing Network yuav qhia rau koj txog qhov sib txawv ntawm cov kabmob refurbished thiab bearing zoo, thiab yuav ua li cas txheeb xyuas seb cov kabmob puas yog cov kabmob refurbished thaum yuav cov kabmob.
Qhov sib txawv ntawm refurbished bearings thiab zoo bearings:
1. Qhov loj ntawm cov kabmob refurbished tau hloov. Cov kab me me sab nraud thiab lub taub loj sab hauv tuaj yeem ntsuas nrog tus pas ntsuas.
2. Txheeb xyuas qhov tseeb ntawm cov kabmob thiab seb nws puas yog du. Refurbished bearings yog ntxhib.
3. Cov kabmob refurbished yog rotated unevenly ntawm tes.
4. Saib xyuas kom pom tias qhov sib txawv ntawm lub tawb thiab cov khoom dov ntawm cov kabmob refurbished yog qhov loj dua qhov sib txawv li qub.
5. Saib cov hlaws refurbished bearing hlaws ntawm ntau qhov sib txawv, thiab yuav muaj hnav thiab deformation.
6. Saib ntawm qhov swb. Lub refurbished bearing slideway muaj irregular hnav thiab deformation.
Ib txoj hauv kev zoo los txheeb xyuas cov kabmob refurbished:
1. Kev kho cov kabmob feem ntau raug txwv los ntawm kev siv tshuab thiab cov khoom siv ntawm cov kabmob me me, yog li cov kabmob raug qis, cov kabmob nto yog ntxhib, qhov loj ntawm chamfer tsis sib npaug, thiab qee qhov muaj cov tawv nqaij dub thiab pitting.
2. Cov ntaub ntawv siv rau qee cov kabmob tsis zoo yog cov hlau zoo tib yam, carbon steel, malleable steel thiab hlau kav, thiab lwm yam, thiab cov tsos ntawm cov ntaub ntawv no feem ntau yog xim dawb, thiab xim ntawm cov kabmob tshwj xeeb yog xim ntsuab. Tab sis tsuas yog saib cov xim tsis tuaj yeem xaus lus tias qhov hardness yuav tsum tau ua. Ordinary steel muaj tsawg hardness.
3. Qee lub tuam txhab me me muaj cov cuab yeej siv yooj yim dipping, thiab cov kabmob tsis sib xws, thiab yuav muaj qhov deformation me ntsis.
4. Tig lub bearings kom pom seb cov kabmob rotates tusyees thiab seb lub suab tsis tu ncua thiab tsis muaj suab nrov.
5. Saib ntawm lub tawb, lub tawb nqa khoom ntawm cov chaw tsim khoom ib txwm muaj tsis tu ncua thiab tsis muaj burrs, lub taub hau ntawm lub riveted bearing tawb yog tib yam, thiab cov cuab yeej ua haujlwm thiab cov khoom siv ntawm cov chaw tsim khoom tsis zoo yog qhov yooj yim, yog li lub tawb yog ntxhib, thiab ib co riveted qauv tawb yog unevenly faib. Nrog los yog tawm tsam qhov offset, qhov loj ntawm lub rivet pier taub hau txawv los yog rivet yog offset.
6. Saib ntawm lub ntim. Cov tuam txhab lag luam niaj hnub muaj tib lub ntim, thiab cov fonts ntawm lub ntim yog qhov tseeb. Qee cov kabmob cuav muaj cov ntim tsis sib xws, lossis yooj yim thiab tsis sib xws.
7. Saib daim font ntawm lub ntsej muag kawg ntawm cov kabmob. Cov kabmob thawj yog qhov tseeb heev thiab tsis hais txog ntawm cov ntawv hlau lossis lub laser font. Lub laser font muaj qhov tob. Cov kabmob cuav font muaj cov cim tawg. Tom qab lub font yog wiped nrog gauze, nws yuav tawm ib tug faint kab ntawm lub font.
8. Saib daim ntawv pov thawj. Cov tuam txhab tsis tu ncua muaj daim ntawv pov thawj thiab qhov loj ntawm daim ntawv pov thawj yog tib yam. Feem ntau ntawm daim ntawv pov thawj yog daim ntawv pov thawj roj. Cov fonts yog qhov tseeb, qee cov tuam txhab lag luam muaj lus nug ntawm daim ntawv pov thawj, daim ntawv pov thawj yog cuav, font yog qhov muag plooj, daim ntawv yog daim ntawv zoo tib yam, thiab qhov loj ntawm daim ntawv pov thawj yog txawv. Nws raug nquahu kom khaws cov chaw tsim khoom tsim daim ntawv pov thawj rau kev sib piv thiab siv.
9. Qee cov kabmob tuaj txawv teb chaws txawv ntawm cov khoom siv hauv tsev raws li cov roj tiv thaiv xeb. Imported bearings tsis yog tsis muaj cov tshuaj tiv thaiv xeb tab sis tsis tuaj yeem pom cov kab. Cov kabmob nto yog qhov tseeb, thaum qee cov kabmob txawv teb tuaj txawv teb chaws yog coated nrog cov neeg sawv cev tiv thaiv xeb thiab hnov ntxhiab hauv tes. Gooey, yuav saj tsis hnov tsw ntawm anti-xeb roj.
10. Nkag siab thiab nkag siab txog cov khoom lag luam ib txwm muaj ntawm qee cov tuam txhab ua lag luam nyob rau hauv cov kabmob typing specifications, xws li: bearing qauv, trademark, xyoo code. Thiab qee qhov fake bearing fonts yog engraved, txawm tias qee qhov fonts yog qhov muag plooj los ntawm laser.
11. Yog tias ua tau, nws yog qhov zoo tshaj plaws mus ntsib cov chaw tsim khoom lag luam lossis cov khw muag khoom ntawm tus kheej.
