Incazelo Yomkhiqizo:

I-needle roller bearing iwuhlobo olukhethekile lwamarola olusebenzisa amarola amade, amancanyana angama-cylindrical afana nezinaliti.Amarola ajwayelekile ama-roller bearing 'amade nje kakhudlwana kunobubanzi bawo, kodwa amabheringi enaliti ngokuvamile anamarola amade ngokuphindwe kane kunobubanzi bawo.[1]Njengawo wonke ama-bearings, asetshenziselwa ukunciphisa ukungqubuzana kwendawo ejikelezayo

Uma kuqhathaniswa nama-ball bearings nama-roller bearings avamile, izinsimbi zezinaliti zinendawo enkulu yokuxhumana nezinhlanga, ngakho zingakwazi ukusekela umthwalo omkhulu.Futhi zincane, ngakho zidinga imvume encane phakathi kwe-axle nesakhiwo esizungezile.

Amabhodi enaliti asetshenziswa kakhulu ezingxenyeni zemoto ezifana nama-rocker arm pivots, amaphampu, ama-compressor, nama-transmissions.I-shaft yokushayela yemoto edonsa ngamasondo angemuva ngokuvamile inamabheringi enaliti okungenani ayisishiyagalombili (amane ejoyintini le-U ngalinye) futhi ngokuvamile abe ngaphezulu uma iyinde ikakhulukazi, noma isebenza emithambekeni eyimiqansa.
