I-ball bearing ejwayelekile iqukethe izindlela zomjaho zangaphakathi nezangaphandle, izinto eziningana eziyindilinga ezihlukaniswe yisithwali, kanye, ngokuvamile, izihlangu kanye/noma izivalo ezenzelwe ukugcina ukungcola kungangeni futhi kufakwe amafutha. Uma ifakiwe, umjaho wangaphakathi uvame ukucindezelwa kancane emgodleni bese umjaho wangaphandle ubanjwa endlini. Imiklamo iyatholakala yokusingatha imithwalo ye-radial emsulwa, imithwalo ye-axial emsulwa (yokusunduza), kanye nemithwalo ye-radial ehlanganisiwe neye-axial.

Ama-ball bearing achazwa ngokuthi anokuxhumana kwephuzu; okungukuthi, ibhola ngalinye lixhumana nomjaho endaweni encane kakhulu - iphuzu, ngokombono. Ama-bearing aklanywe ngendlela yokuthi ukuguquguquka okuncane okwenziwa yibhola njengoba ligingqika lingena futhi liphuma endaweni yomthwalo akudluli iphuzu lokukhiqiza lezinto; ibhola elingalayishiwe libuyela esimweni salo sokuqala. Ama-ball bearing awanakho ukuphila okungenamkhawulo. Ekugcineni, ayahluleka ngenxa yokukhathala, ukuqhekeka, noma ezinye izimbangela eziningi. Aklanywe ngokwezibalo ngempilo ewusizo lapho inani elithile kulindeleke ukuthi lihluleke ngemva kwenani elibekiwe lokujikeleza.

Abakhiqizi banikeza ama-radial bearings anomugqa owodwa ochungechungeni olune ngobukhulu obujwayelekile be-bore. Ama-angular contact bearings aklanyelwe ukumelana nomthwalo we-axial ohlangothini olulodwa futhi angaphindeka kabili ukuze aphathe umthwalo we-thrust ngezindlela ezimbili.

Ukuqondanisa ishafti kanye namabhereyi kudlala indima ebalulekile empilweni yokuthwala. Ukuze kube nomthamo ophezulu wokungahambisani, kusetshenziswa amabhereyi azilungisayo.

Ukuze kwandiswe umthamo womthwalo we-radial, isithwali sokuthwala siyasuswa bese isikhala esiphakathi kwemijaho sigcwaliswe ngamabhola amaningi ngangokunokwenzeka—okuthiwa yi-full-complement bearing. Ukuguga kwala ma-bearing kuphakeme kunalawo asebenzisa izithwali ngenxa yokuhlikihla phakathi kwezinto ezigoqekayo eziseduze.
Ezimweni ezibucayi lapho ukugeleza komgodi kuyinkinga—isibonelo, ama-spindle amathuluzi omshini—ama-bearings angase alayishwe kusengaphambili ukuze athathe noma yikuphi ukuvuleka kwe-bearings assembly esebekezelelwe kahle.
