Ha u khetha mofuta oa bere, lintlha tse hlano tse latelang li lokela ho nahanoa:

1) Tataiso, boholo le mofuta oa mojaro: Li-radial bears li jara meroalo ea radial, li-thrust bears li amohela meroalo ea axial.Ha ho beoa ho tlas'a meroalo ea radial le axial, li-angular ball bearings le li-roller bearings li ka khethoa.Ha mojaro oa axial o le monyane, li-bearings tse tebileng tsa groove ball le tsona li ka sebelisoa.Ka kakaretso, matla a ho jara a li-roller INA bearings a phahame ho feta a li-bearings tsa INA, 'me bokhoni ba ho mamella meroalo ea tšusumetso bo matla.

2) Lebelo: Lebelo la ho sebetsa la ho beha hangata le lokela ho ba tlase ho feta lebelo la moeli n.Lebelo le lekanyelitsoeng la li-bearings tsa bolo ea groove tse tebileng, li-angular ball bearings le li-cylindrical roller bearings li phahame, tse loketseng ho sebetsa ka lebelo le phahameng, ha lebelo la moeli oa li-bearings tse phunyeletsang le tlaase.

3) Ts'ebetso ea ho ikamahanya le maemo: Ha ho kopanngoa ha likoti tse peli tse nang le matlo a mabeli ho ke ke ha tiisetsoa kapa ho kheloha ha shaft ho le leholo, u lokela ho nahana ka ho sebelisa li-bearings tsa bolo ea spherical kapa li-roller bearings.

4) Litlhoko tsa ho satalla: Ka kakaretso, boima ba li-roller bearings bo boholo ho feta ba li-bearings tsa INA, 'me li-angular-contact ball bearings le li-roller bearings li ka etsoa pele ho tsitsipano ho eketsa ho tiea ha tšehetso.

5) Litlhoko tsa moeli oa tšehetso: Litšehetso tse tsitsitseng li fokotsa ho falla ha axial ka litsela tse peli.Li-bearings tse khonang ho mamella meroalo ea axial ea bidirectional li ka khethoa.Meeli ea tsela e le 'ngoe e ka khethoa ka li-bearings tse ka tšehetsang meroalo ea axial unidirectional.Ha ho na moeli ho litšehetso tse phaphametseng.Boemo, ho ka khetha cylindrical rolara behang eo ka hare le ka ntle mehele ka aroloa.
