1. Hom N0000 cylindrical roller bearings (ntiv nplhaib sab nraud yam tsis muaj flange) thiab hom NU0000 cylindrical roller bearings ( puab nplhaib tsis muaj flange): Cov kabmob no tuaj yeem tiv taus cov khoom loj radial, muaj kev txwv siab, tsis txwv axial txav ntawm lub ncej lossis vaj tse, tab sis tsis tuaj yeem tiv taus axial loads.
2. Cylindrical roller bearings nrog flanges ntawm ob sab hauv thiab sab nraud rings (hom NJ0000 thiab NF0000): Cov kabmob no tuaj yeem txwv axial txav ntawm lub ncej lossis vaj tse nyob rau hauv ib qho kev taw qhia thiab tuaj yeem tiv taus me me unidirectional axial loads. Hom NU0000+HJ0000, NJ0000+HJ0000, thiab NUP0000 bearings tuaj yeem txwv tsis pub axial txav ntawm lub ncej lossis vaj tse nyob rau hauv ob qho tib si cov lus qhia nyob rau hauv axial clearance ntau yam ntawm cov kabmob txawv teb chaws thiab tuaj yeem tiv taus me me bidirectional axial loads.
