Combined koob rau cov menyuam bearings

Covsib xyaw koob rau cov menyuam bearingyog ib lub bearing unit uas muaj xws li radial koob rau cov menyuam bearing thiab thrust bearing los yog angular contact pob bearing Cheebtsam, uas yog compact nyob rau hauv cov qauv, me me loj, siab nyob rau hauv kev sib hloov raug, thiab muaj peev xwm dais ib tug tej yam axial load thaum bearing ib tug siab radial load. Thiab cov qauv khoom muaj ntau haiv neeg, yoog raws thiab yooj yim rau nruab.

Nws yog dav siv hauv tshuab cuab yeej, metallurgical machinery, textile machinery thiab tshuab luam ntawv.

Combined koob rau cov menyuam bearingsyog siv nyob rau hauv sib txuam ncej tsim raws li ib tug bearing raceway, uas muaj tej yam yuav tsum tau rau lub hardness ntawm cov kabmob; Los yog nrog lub tuam txhab tshwj xeeb IR tus qauv sab hauv lub nplhaib rau kev kho lub tes tsho, tsis muaj qhov yuav tsum tau ua rau lub taub hau hardness, thiab nws cov qauv yuav ntau dua.

Nws yog dav siv nyob rau hauv ntau yam khoom siv kho tshuab xws li cov cuab yeej siv tshuab, metallurgical machinery, textile machinery thiab tshuab luam ntawv, thiab tuaj yeem ua rau cov tshuab tshuab tsim ntau compact thiab hloov tau.

 

Qauv qauv

Cov kabmob no muaj cov kabmob radial rab koob thiab lub pob thrust tag nrho, lossis lub pob thrust, lossis ib lub cylindrical roller, lossis lub pob angular hu tag nrho, thiab tuaj yeem nqa unidirectional lossis bidirectional axial loads. Nws tuaj yeem tsim tau raws li cov qauv tsim tshwj xeeb ntawm cov neeg siv khoom.

 

Cov khoom raug

Dimensional kam rau ua thiab geometric raug raws li JB/T8877.

Txoj kab uas hla ntawm rab koob rau cov menyuam yog 2μm, thiab qib raug yog G2 (tus qauv hauv tebchaws GB309).

Txoj kab uas hla ntawm lub voj voog inscribed ua ntej sib sau ua ke ntawm cov kabmob uas tsis muaj lub nplhaib sab hauv ua tau raws li chav kawm kam rau ua F6.

Lub radial clearance ntawm cov kabmob ua raws li tus nqi teev ntawm pawg 0 ntawm GB / T4604.

Qhov tseeb tshwj xeeb yog GB / T307.1.

Rau cov ntsiab lus ntawm qhov tshwj xeeb uas yuav tsum tau ntawm bearing clearance, inscribed lub voj voog thiab qhov tseeb, thov hu rau peb lub tuam txhab(sales@cwlbearing.com&service@cwlbearing.com)

 

 

khoom

Cov khoom siv rab koob yog GCr15 bearing steel, hardened HRC60-65.

Sab hauv thiab sab nrauv yog ua los ntawm GCr15 bearing steel thiab hardened HRC61-65.

Cov khoom siv tawb yog cov hlau me me los yog cov nylon reinforced.

　　

Cov lus qhia tshwj xeeb

Lub axial load ntawm NKIA thiab NKIB series bearings yuav tsum tsis pub tshaj 25% ntawm radial load.

Bearings rau alternating axial loads yuav tsum tau ntsia opposite.

 

Thrust bearing Cheebtsam yuav tsum tau preloaded mus txog 1% ntawm cov axial yooj yim static load ntsuam xyuas.

Thaum siv lub tawb yas (suffix TN), kev ua haujlwm kub yuav tsum tsis pub tshaj + 120 ° C rau kev ua haujlwm tas mus li.

Thrust bearing Cheebtsam yuav tsum txav mus rau hauv lub vaj tse.

Kev tsim qauv dav dav ntawm cov kabmob yog pom zoo nyob rau hauv daim ntawv thov kev siv tshuab dov bearing.
