NN3012KTN/SP Super-precision Ob-kab cylindrical roller bearing
Yog li ntawd, cov bearings no tshwj xeeb tshaj yog rau cov cuab yeej siv tshuab uas qhov kev npaj ntawm cov kabmob yuav tsum ua raws li cov khoom hnyav radial thiab kev kub ceev, thaum muab cov qib siab ntawm kev tawv, ob kab bearings yog qhov tsim nyog dua rau cov khoom hnyav dua.
Ob kab cylindrical roller bearings muaj ob lub qauv: cylindrical sab hauv lub qhov thiab conical sab hauv lub qhov (tus lej tom qab ntawm tus kabmob ntxiv rau K). Lub qhov conical sab hauv kuj tseem tuaj yeem ua lub luag haujlwm ntawm kev kho qhov me me ntawm qhov chaw, thiab tuaj yeem ua kom yooj yim rau cov qauv ntawm lub cuab yeej tso chaw thiab pab txhawb kev teeb tsa thiab kev sib cais.
Cov kabmob cylindrical roller uas siv ntau tshaj plaws muaj cov hom hauv qab no: NN series, NNU series, thiab NNF series. Kev kam rau siab: SP, UP, SP thiab UP rau 1:12 tapered bore.
