Amasoko y'umuhengeri yaguka cyane nkuko bigabanijwe kuva muburebure bwubusa kugeza murwego rwakazi. Uku kwaguka gusobanurwa na formula $ \ Delta D \ hafi 0.02 \ cdot \ frac {(L_f - L_w) \ cdot t} {N} $, aho $ L_f $ nuburebure bwubusa naho $ L_w $ nuburebure bwakazi. Niba isoko yamenetse muri bore ifite ibihagije bidahagije, diameter yo hanze (OD) izahuza nurukuta rwamazu. Uku guhambira gutera guterana gukabije, kugaragara nkikigereranyo kirenze-cyabazwe cyimpeshyi kandi gitera kwambara cyangwa 'fretting'. Ku mpeshyi ya Crest-to-Crest, ni ngombwa kubara OD ntarengwa ku burebure bukomeye $ H_s $ kugirango tumenye ko igumye munsi ya diameter ntoya ya $ D_b $ mubikorwa byose.
