Ukuzalaingenye yezingxenye ezisetshenziswa kakhulu zemishini, ezithwala ukujikeleza nokunyakaza okuphindaphindiwe kwe-shaft, ukuze ukunyakaza kwe-shaft kube bushelelezi futhi kuyisekele. Uma kusetshenziswa ama-bearings, ukungqubuzana nokuguga kungancishiswa. Ngakolunye uhlangothi, uma ikhwalithi yokuthwala iphansi, izobangela ukwehluleka komshini, ngakho-ke ukuthwala kubhekwa njengenye yezingxenye ezibalulekile zemishini.

Kunezinhlobo ezimbili eziyinhloko zama-bearings: ama-sliding bearings kanyeama-bearings aginqikayo.

I-Plain bearing:

Ama-bearings angenalutho ngokuvamile akhiwa isihlalo esithwalayo kanye nesihlahla esithwalayo. Kuma-bearings angenalutho, i-shaft ithintana ngqo ne-bearing surface. Ingakwazi ukumelana nesivinini esikhulu kanye nomthwalo onomthelela. Ama-plain bearings asetshenziswa ezinjini zezimoto, imikhumbi nemishini.

Yifilimu yamafutha esekela ukujikeleza. Ifilimu yamafutha ifilimu encane yamafutha. Lapho izinga lokushisa likawoyela likhuphuka noma ligcwele ngokweqile, ifilimu yamafutha izoba mncane, ibangele ukuthintana kwensimbi futhi ibangele ukushisa.

Ezinye izici zifaka:

1. Umthwalo ovunyelwe mkhulu, ukudlidliza nomsindo kuncane, futhi ukusebenza kungathula.

2. Ngokwenza isimo sokugcoba nokugcinwa, impilo yesevisi ingasetshenziswa unomphela.

I-Rolling bear:

Ama-rolling bearings anebhola noma i-roller (ibha eyindilinga) ukunciphisa ukumelana nokushwibilika. Ama-rolling bearings afaka: ama-deep groove ball bearings, ama-angular contact ball bearings, tapered roller bearings, ama-thrust bearings, njll.

Ezinye izici zifaka:

1. Ukungqubuzana kokuqala okuphansi.

2. Uma kuqhathaniswa nama-bearings ashelelayo, kukhona ukungqubuzana okuncane.

3.Ngoba ubukhulu nokunemba kumisiwe, kulula ukuzithenga.

Sengiphetha, ama-bearings angenye yezingxenye ezisetshenziswa kakhulu (izingxenye ezijwayelekile) ekwakhiweni kwemishini. Ukusebenzisa kahle ama-bearings kungathuthukisa ukusebenza kwemikhiqizo futhi kunciphise izindleko, ngakho-ke kubaluleke kakhulu ukwazi kahle ulwazi olufanele lwama-bearings.
