Lapho ukhetha uhlobo lokuthwala, izici ezinhlanu ezilandelayo kufanele zibhekwe:

1) Isiqondiso, usayizi kanye nemvelo yomthwalo: Ama-radial bears ikakhulukazi athwala imithwalo ye-radial, ama-thrust bears athola imithwalo ye-axial.Uma ukuthwala kungaphansi kokubili kwemithwalo ye-radial ne-axial, ama-angular amabhola okuxhumana nama-roller ama-tapered angakhethwa.Uma umthwalo we-axial umncane, ama-deep groove ball bearings angasetshenziswa.Ngokuvamile, amandla okuthwala ama-roller INA bearings angaphezulu kwalawo ama-ball INA bearings, futhi amandla okumelana nemithwalo yethonya anamandla.

2) Isivinini: Isivinini sokusebenza se-bearing kufanele sibe ngaphansi kwesivinini esilinganiselwe n.Ijubane elilinganiselwe lama-deep groove ball bearings, ama-angular ball bearings nama-cylindrical roller bearings liphezulu, elifanele ukusebenza ngesivinini esiphezulu, kuyilapho isivinini somkhawulo wama-thrust bearings siphansi.

I-3) Ukusebenza kokuziqondanisa ngokwakho: Uma ukubumbana kwezimbobo zezindlu ezithwele akukwazi ukuqinisekiswa noma ukuchezuka kwe-shaft kukhulu, kufanele ucabange ukusebenzisa ama-spherical ball bearings noma ama-roller bearings ayindilinga.

I-4) Izidingo zokuqina: Ngokuvamile, ukuqina kwama-roller bearings kukhulu kunebhola le-INA bearings, futhi ama-angular ball bearings nama-tapered roller bearings angakwazi ukufakwa ngaphambili ukuze aqhubeke nokwandisa ukuqina kokusekelwa.

I-5) Izidingo zomkhawulo wokusekela: I-Fixed isekela umkhawulo wokufuduka kwe-axial ngezindlela ezimbili.Ama-Bearings angakwazi ukumelana nemithwalo ye-axial ye-bidirectional angakhethwa.Imikhawulo yendlela eyodwa ingakhethwa ngama-bearings angasekela imithwalo ye-axial engaqondile.Awukho umkhawulo kuzisekelo ezintantayo.Isikhundla, singakhetha i-cylindrical roller bearing okungakwazi ukuhlukaniswa amasongo angaphakathi nangaphandle.
