Irolalm izikhokeloithatha i-roller njengezinto eziqengqelekayo endaweni yeebhola zentsimbi, inokubonelela ngobulukhuni obuphezulu kunye nomthamo ophezulu kakhulu womthwalo, iileyili zesilayidi ezithwele i-roller ziyilelwe nge-angle ye-45 ye-degree yoqhagamshelwano evelisa i-deformation encinci ye-elastiki ngexesha lomthwalo ophezulu kakhulu, ithwala umthwalo olinganayo kuwo onke amacala kunye nokuqina okufanayo okuphezulu. Ke izikhokelo ze-PRG roller zinokufikelela kwiimfuno ezichanekileyo eziphezulu kunye nobomi obude benkonzo.
Uhlobo lwerola yesikhokhelo somgcainomthwalo onzima onzima, ongekho lula ukukhubazeka, wamkela ulungelelwaniso lwe-roller, umthamo ophuculweyo womthwalo kunye nofakelo olulula, ukuthwala umgca wesikwere kwamkela umgangatho ophezulu wokuthwala intsimbi ekwazi ukunxiba, ukuqina okuqinileyo kunye nomthwalo onzima.
lm ukhetho lwezikhokelo, Iukuchanekayochungechunge lwe-PRG lunokuhlelwa kwiiklasi ezine: eziphezulu (H), ukuchaneka (P), ukuchaneka okuphezulu (SP) kunye nokuchaneka kwe-ultra (UP). Umthengi unokukhetha iklasi ngokubhekisela kwiimfuno zokuchaneka kwezixhobo ezisetyenzisiweyo.
Ngokusebenzisa izinto ezijikelezayo, ezifana ne-roller phakathi komzila kunye nebhloko, isikhokelo somgca sinokufikelela ngokuchanekileyo okuphezuluintshukumo yomgca. Ibhloko yesikhokelo somgca yahlulahlulwe ngohlobo lwe-flange kunye nohlobo lwesikwele , ibhloko yohlobo oluqhelekileyo, ibhloko yokuthwala kabini, uhlobo olufutshane lwebhloko. Kwakhona, ibhloko yomgca yahlulahlulwe kumthamo ophezulu womthwalo kunye nobude obuqhelekileyo bebhloko kunye nomthamo ophezulu womthwalo ophezulu kunye nobude bebhloko ende.
