Imirongo ibiri ya silindrike ya roller ifite imbavu kumpeta y'imbere kandi nta rubavu ku mpeta yo hanze. Impeta y'imbere hamwe na roller hamwe na kage inteko irashobora gutandukana nimpeta yinyuma. Uruzitiro rushobora kwemererwa kubyara icyerekezo cya axial mu byerekezo bibiri ugereranije n’amazu afite, kandi bikagira imitwaro minini ya radiyo.
Imirongo ine ya silindrike ya roller ifite imbavu kumpeta yinyuma kandi nta rubavu kumpeta y'imbere. Impeta yo hanze hamwe na roller hamwe na kage inteko irashobora gutandukana nimpeta yimbere. Wikore umutwaro munini wa radiyo n'umutwaro.
