Cylindrical roller bearings feem ntau tsis muaj txoj cai nruj thiab tsis ncaj ncees, tab sis kev saib xyuas yuav tsum tau them rau cov ntsiab lus xws li cov qauv tawb thiab lubrication qhov thaum lub sij hawm installation. Cylindrical roller bearings yog dov bearings nrog siab radial load peev. Lawv cov ntsiab lus dov yog cylindrical rollers uas ua rau txoj kab sib txuas nrog lub nplhaib sab hauv thiab sab nrauv, ua rau lawv tsim nyog rau cov kabmob loj radial. Structurely, feem ntau cylindrical cov menyuam bearings yog symmetrically tsim thiab theoretically yuav muab ntsia tau rau hauv ob qho tib si qhia. Txawm li cas los xij, hauv kev siv tswv yim, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
1. Rau cov bearings nrog tawb, xyuas kom meej tias lub tawb qhib lub ntsej muag tsis yog -thawj load sab;
2. Rau cov qauv nrog lubrication qhov los yog cov ntsaws ruaj ruaj, xyuas kom meej tias qhov chaw ua haujlwm tau ntsib lub lubrication qhov chaw;
3. Ob npaug - kab bearings tej zaum yuav muaj preload cov lus qhia. Thaum lub sij hawm installation, nws raug nquahu kom xa mus rau cov kabmob qhov kawg ntawm lub ntsej muag (xws li, cov chaw tsim khoom lub logo feem ntau ntsib sab nraud), thiab xyuam xim tshwj xeeb rau lub nplhaib mating kev taw qhia ntawm cov kabmob sib cais xws li NU / NJ hom. Cov kev cai tshwj xeeb rau cov qauv sib txawv tuaj yeem pom hauv ISO 15: 2017 tus qauv lossis cov chaw tsim khoom siv phau ntawv qhia.
