N307-E ib kab Cylindrical cov menyuam bearing
Ib kab cylindrical cov menyuam bearings nrog ib lub tawb uas muaj cylindrical rollers caged ntawm ib lub nplhaib sab nraud thiab sab hauv. Cov bearings no muaj lub siab rigidity, tuaj yeem txhawb nqa hnyav radial loads thiab haum rau kev kub ceev. Lub nplhaib sab hauv thiab sab nraud tuaj yeem sib cais, ua rau kev teeb tsa thiab tshem tawm cov txheej txheem yooj yim.
Lub nplhaib sab nraud ntawm N series cylindrical bearing tsis muaj ribs, whereas lub nplhaib puab ntawm lub cylindrical bearing muaj ob lub tav tav. Qhov no txhais tau hais tias N series cylindrical bearing tsis tuaj yeem nrhiav tus ncej, yog li qhov axial txav ntawm tus ncej txheeb ze rau lub casing tuaj yeem nyob hauv ob qho tib si.
Pressed steel lossis machined tooj dag tawb feem ntau yog siv, tab sis qee zaum molded polyamide tawb kuj siv.
N307-E ib kab Cylindrical roller bearing, "E" suffix designates ntau dua radial load peev.
