Ma bearing ozungulira ozungulira ndi ma bearing ozungulira okhala ndi mizere imodzi kapena iwiri ya ma rollers ooneka ngati mbiya omwe ali pa ngodya ku axis yozungulira. Ma bearing ozungulira ozungulira ndi oyenera kugwiritsidwa ntchito m'makampani akuluakulu chifukwa amatha kuthana ndi kusakhazikika bwino komanso kusamutsa shaft. Ma Spherical Roller Bearing amakhala ndi kukhazikika kwa dimensional, amatha kuthandizira katundu wolemera wa radial komanso katundu wocheperako wa axial.
