Cylindrical roller bearings feature kab kev sib cuag ntawm cov menyuam thiab cov raceways. Lawv muaj peev xwm ua haujlwm siab thiab feem ntau dais radial loads. Kev sib txhuam ntawm cov khoom dov thiab cov kev sib tw flanges tsawg, ua rau lawv haum rau siab - kev sib hloov ceev. Nyob ntawm seb cov kev sib tw puas muaj flanges, lawv tuaj yeem raug faib ua ib leeg - kab cylindrical roller bearings (NU, NJ, NUP, N, NF, thiab lwm yam) thiab ob npaug - kab cylindrical roller bearings (NNU, NN, thiab lwm yam). Cov kabmob no muaj lub nplhaib sab hauv thiab sab nraud sib cais.
Cylindrical roller bearings tsis muaj flanges ntawm lub nplhaib sab hauv lossis sab nraud tso cai rau axial txav ntawm sab hauv thiab sab nraud, ua rau lawv tsim nyog siv dawb -kawg bearings. Cylindrical roller bearings nrog ob lub flanges ntawm ib sab ntawm sab hauv thiab sab nraud thiab ib qho flange rau sab nraud tuaj yeem tiv taus qee qhov kev thauj khoom axial hauv ib qho kev coj. Lawv feem ntau siv stamped steel tawb lossis machined khoom tooj liab alloy tawb. Txawm li cas los xij, qee tus kuj siv molded polyamide tawb.
