Mugihe ushyiraho ibitsike, reba perpendicularity yimpeta yumurongo hamwe numurongo wo hagati wigitereko.Uburyo nugukosora ibipimo byerekana kumurongo wanyuma wurubanza, kora imibonano ya metero ihagarare kumuhanda wa KOYO ifite impeta ya shaft hanyuma uhindure KOYO mugihe witegereje icyerekezo cyerekana ibimenyetso.Niba icyerekezo gitandukiriye, bivuze ko impeta ya shaft n'umurongo wo hagati wa shaft bidahuye.uhagaritse.Iyo umwobo wimbitse wimbitse, urashobora kandi kugenzurwa numutwe wagutse werekana umutwe.

Iyo icyuma gisunika gishyizwe neza, impeta yacyo irashobora guhita ihinduranya no kuzunguruka ibintu kugirango irebe ko ibintu bizunguruka biherereye mumihanda yimpeta yo hejuru no hepfo.Niba yarashizwe hejuru, ntabwo KOYO yonyine itazakora muburyo busanzwe, ariko kandi hejuru yubukwe bizambara cyane.Kubera ko itandukaniro riri hagati yimpeta nimpeta yintebe itagaragara, hagomba kwitabwaho cyane mugihe cyo guterana, kandi ntakosa rigomba gukorwa.Byongeye kandi, hagomba kubaho icyuho cya 0.2-0.5mm hagati yimpeta yintebe yikizunguruka hamwe na KOYO ifite umwobo wintebe kugirango yishyure amakosa yatewe no gutunganya ibice bidahwitse no kuyishyiraho.Iyo hagati yimpeta ya KOYO ihagaritswe mugihe cyo gukora, Uku gukuraho kwemeza ko ihita ihinduka kugirango yirinde guterana amagambo, ikemerera gukora neza.Bitabaye ibyo, bizatera kwangirika gukabije kwa KOYO.
