Ubusobanuro bwo kwifata burimo ibintu bisobanutse kandi bizunguruka neza ni umushinga uzamuka kuri shitingi, urimo imbere ya diameter, imbere ya diameter, ubugari, kwihanganira ubunini bwa chamfer cyangwa agaciro kemewe. gutandukana, impuzandengo ya diametre impuzandengo itandukanijwe nindege imwe ya radiyo.kuri kwizunguruka ni kuzunguruka Pendulum, harimo impeta yimbere hamwe nimpeta yimbere ya radiyo swing hamwe na axial runout, Kuruhande rwimpeta yimbere hamwe na diametre yinyuma ya perpendicularity kwihanganira.Gutanga amanota yuzuye kuva murwego rusange 0 kugeza 6, 5, icyiciro cya 4 nicyiciro cya 2, nacyo, hepfo ni kugereranya imbonerahamwe hagati yicyiciro cya mbere cya china GB 307 nibindi bipimo bisobanutse neza. 

Impeta yo hanze 11, impeta y'imbere 12, n'umupira wa 13 urimo ibice ni 0,95 misa% cyangwa irenga na 1,10 mass% cyangwa munsi ya karubone, 0,05% cyangwa irenga na munsi ya 0.3 mass silicon, 0,10 mass% cyangwa irenga na 0,50 misa% 11 A yumuhanda wimpeta yo hanze na 12 A yumuhanda wimbere wimbere aribwo buso bugizwe nicyuma kigizwe na manganese ikurikira, 1,30 mass% cyangwa irenga, na 2.00 mass% cyangwa munsi yayo, kandi igizwe nibyuma aribyo igizwe nicyuma gisigaye nicyanduye, hamwe nuguhuza nibindi bice.Impuzandengo ya azote igereranije mukarere ka 11B, 12B, na 13B aribwo turere mubwimbye bwa 20 mm kuva umupira uzunguruka 13A ni 0.2% kubwinshi cyangwa byinshi na 0.7% kubwinshi cyangwa munsi, no hejuru uturere twibice 11B, 12B, 13B, 5 cyangwa byinshi karbide ifite diameter ya micrometero 0.5 cyangwa munsi yayo ibaho kuri micrometero 100.
