NNU4148-M

CovNNU4148-Myog lub siab -kev ua tau zoo ob npaug- kab cylindrical roller bearing engineered rau daim ntawv thov xav tau huab radial rigidity thiab precision. Featuring ib240mm uathiab muaj zog400mm sab nraud txoj kab uas hla, chav tsev no yog tsim los nrog cov khoom siv tooj dag (M suffix) uas muab cov lus qhia zoo tshaj rau cov menyuam thiab ua kom muaj zog nyob rau hauv hnyav - lub luag haujlwm. Tsis zoo li tus qauv ib zaug - kab lwm txoj hauv kev, NNU tsim muaj lub nplhaib sab hauv tsis muaj ribless thiab triple -ribbed lub nplhaib sab nraud, tso cai rau kev hloov pauv ntawm axial tseem ceeb. Qhov no ua rau nws yog qhov zoo tshaj plaws "tsis yog- nrhiav" cov kabmob kev xaiv rau loj- nplai kev lag luam, xws li hnyav- lub luag haujlwm gearboxes thiab dov mills, qhov thermal expansion ntawm lub ncej yog qhov tseem ceeb.

Los ntawm ib tug technical standpoint, lubNNU4148-Mstands rau nws impressive load- nqa peev xwm, ntsuas rau ib tug zoo li qub load ($C_{0}$) ntawm kwv yees li $3600\\text{kN}$. Kev sib koom ua ke ntawm lub tshuab tooj dag lub taub hau txo qis kev sib txhuam ntawm kev kub ceev, ncua kev pab cuam lub neej ntawm cov roj nplua nyeem thiab cov kabmob nws tus kheej. Nws cov qauv sib cais yog lwm qhov zoo dua, ua kom yooj yim rau kev txhim kho thiab tshem tawm cov txheej txheem thaum lub sijhawm tu. Txawm hais tias siv nyob rau hauv lub ntsiab spindles ntawm precision tshuab cuab yeej los yog nyob rau hauv lub xav tau ib puag ncig ntawm cov khoom siv tsuas, NNU4148-M muab cov kev khiav hauj lwm siab thiab cov qauv nruj uas yuav tsum tau los txo qis kev co thiab xyuas kom meej lub sij hawm ua hauj lwm stability.
