I-roller bearing eziqondanisayo inomugqa ophindwe kabili wama-roller, indandatho yangaphandle inomjaho oyindilinga ovamile, iringi yangaphakathi inemizila emibili yomjaho futhi itshekele ku-Angle ngokuhlobene ne-axis ethwalayo. Lesi sakhiwo esihlakaniphile siyenza ibe nokusebenza kokuqondanisa okuzenzakalelayo, ngakho-ke akulula ukuthintwa i-Angle ye-shaft nesihlalo sebhokisi elithwele iphutha noma ukugoba kwe-shaft, futhi ifanele iphutha lokufaka noma ukuchezuka kwe-shaft okubangelwa izikhathi zamaphutha e-Angle. Ngaphezu komthwalo we-radial, ukuthwala kungabuye kuthwale umthwalo we-axial wesenzo sokuqondiswa kabili.
Izinhlelo zokusebenza eziyinhloko: imishini yokwenza iphepha, i-reducer, i-asi yemoto yesitimela, isihlalo esiphethe ibhokisi legiya eliginqikayo, i-rolling mill roller, i-crusher, isikrini esidlidlizayo, imishini yokuphrinta, imishini yokwenza ukhuni, zonke izinhlobo zokuncishiswa kwezimboni, ukuqondanisa okuqondile okuhambisana nesihlalo.
