Ka hona, li-bearings tsena li loketse ka ho khetheha bakeng sa li-spindle tsa lisebelisoa tsa mochine moo tokisetso ea ho jara e tlamehang ho amohela meroalo e boima ea mahlaseli le lebelo le phahameng, ha e ntse e fana ka tekanyo e phahameng ea ho satalla, li-bearings tsa mela e 'meli li loketse ho feta meroalo e boima.
Lirolara tse nang le mela e 'meli ea li-cylindrical li na le likarolo tse peli: cylindrical inner bore le conical internal bore (khoutu e ka morao hammoho le K). Sekoti se ka hare sa conical se ka boela sa bapala karolo ea micro-adjustment ea clearance, 'me e ka nolofatsa sebopeho sa sesebelisoa sa boemo le ho thusa ho kenya le ho qhaqhoa.
Li-roller tsa li-cylindrical tse tloaelehileng tse sebelisoang ka makhetlo a mabeli li na le mefuta e latelang: NN series, NNU series, le NNF series.Tolerances: SP, UP, SP le UP bakeng sa 1:12 tapered bore.
