Izinga lokuthwala kanye nokukhethwa kwezinto ezibonakalayo akuhlukaniseki ngesikhathi sokusebenzisa ukuthwala.Ngakho-ke, sidinga ukukhetha impahla ethile ye-bearing ngokusho kwezidingo ezithile zekhasimende.Ngakho-ke yiziphi izici zezinto ezithwala insimbi?Ngokusekelwe ekuqondeni, izici zokusebenza ezilandelayo zokuthwala izinto zensimbi zibalwe.

I-Bearing steel kufanele ibe nezinto ezilandelayo:

1. Amandla okukhathala okuxhumana aphezulu.

2. High ukumelana nemihuzuko.

3. Umkhawulo wokunwebeka okuphezulu namandla okukhiqiza.

4. Ukuqina okuphezulu nokufana.

5, ukuqina komthelela othile.

6. Ukuzinza okuhle kwe-dimensional.

7, ukusebenza okuhle kokuvimbela ukugqwala.

8. Ukusebenza kahle kwenqubo.

Ukukhethwa kwezinto ezithwala insimbi nakho kudinga ukuthenga okuthile.Okwezinto ezithwalayo ezisebenza ngaphansi kwezimo ezikhethekile, ngokwezidingo zazo ezithile, kufanele futhi zibe nezakhiwo ezikhethekile ezihambisana nezimo zazo, njengokuthi: ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala, I-Anti-radiation, i-anti-magnetic kanye ezinye izici.
