Cov kabmob cylindrical roller ib kab nrog lub tawb uas muaj cov menyuam cylindrical nyob nruab nrab ntawm lub nplhaib sab nraud thiab sab hauv. Cov kabmob no muaj kev ruaj khov siab, tuaj yeem txhawb nqa cov khoom hnyav radial thiab tsim nyog rau kev kub ceev. Cov nplhaib sab hauv thiab sab nraud tuaj yeem sib cais, ua rau kev teeb tsa thiab kev tshem tawm yooj yim.
Lub nplhaib sab nraud ntawm NUP cylindrical bearing muaj ob lub tav ruaj khov, thaum lub nplhaib sab hauv ntawm cylindrical bearing muaj ib lub tav ruaj khov thiab ib lub tav xoob. Qhov no txhais tau tias NUP cylindrical bearing muaj peev xwm nrhiav tau lub qag hauv ob qho kev taw qhia.
