O nei bearings o loʻo faʻaalia i latou foliga cylindrical ma rollers o loʻo faʻatulagaina faʻatasi i le axis of rotation.O lo'o ta'ita'iina e ala ta'avale i luga o mama i totonu ma fafo, e mafai ai ona latou tatalia avega fa'aala ma axial.Faatasi ai ma lenei mamanu tulaga ese, e mafai ona ausia e a tatou paʻu taʻavale cylindrical le saoasaoa maualuga ma gaioiga saʻo, ma faʻaogaina lelei mo le faʻaaogaina i galuega mamafa e pei o masini masini, mea faufale, ma masini taʻavale:
1. laina taʻavale taʻavale cylindrical tasi: NU, NJ, NUP, N, NF ma isi faʻasologa.
2. Laina fa'alua fa'aigoa fa'aigoa pa'u: NN, NNU, NNF, NNCL ma isi fa'asologa.
