Mugihe kugumana impeta akenshi bifatwa nkibigize static, birashobora kugira umunaniro mugihe igice cyagumishijwe gikoresha umutwaro wikizunguruka (urugero, mugiterane cya piston). Umunaniro usanzwe utangirira kumpera yimbere yimpeta bitewe nigihe cyo kugunama cyakozwe nkimpeta 'ibyokurya' mumashanyarazi. Urwego rwo guhangayika $ Δ \ sigma $ rugenwa no gukina hagati yimpeta na groove. Niba igikoni ari kinini cyane, impeta irashobora 'inyundo' kurukuta, bikongerera imbaraga imbaraga. Isesengura rya SEM risanzwe ryerekana 'striations' ziranga umunaniro. Kugira ngo wirinde ibi, inteko igomba gutegurwa hamwe na nyuma ya axial end-play, kandi ibikoresho byimpeta bigomba kuzamurwa kugeza kuri 17-7PH kugirango bigabanye umunaniro mwinshi.
