Ukuchaneka kokuchaneka kuqulethe ukuchaneka kunye nokujikeleza ukuchaneka komgangatho wokuchaneka yiprojekthi ekhwela kwi-shafts, ibandakanya i-diameter yangaphakathi, i-diameter yangaphandle, ububanzi, ukunyamezela ubungakanani be-chamfer okanye ixabiso elivumelekileyo. ukutenxa, i-avareji ye-avareji yesangqa yobubanzi bokutenxa kwi-plane ye-radial enye. ukuchaneka kokujikeleza kujikeleza i-Pendulum, kuquka i-ring yangaphakathi kunye ne-ring yangaphandle ye-radial swing kunye ne-axial runout, Icala lomsesane wangaphakathi kunye nobubanzi obungaphandle be-perpendicularity ukunyamezela uluhlu. I-0 ukuya ku-6, i-5, i-grade 4 kunye ne-grade 2, ngokulandelayo, ngezantsi kuthelekiso lwetheyibhile phakathi kweklasi ye-preeision yase-china GB 307 kunye neminye imigangatho echanekileyo.I-Giant bearing precision grade ivela kwi-grade 6, 5, 4 kunye ne-2 yamanqanaba amane. 

I-ring yangaphandle ye-11, i-ring yangaphakathi ye-12, kunye ne-13 yebhola eneenxalenye ezithwele i-0.95 mass% okanye ngaphezulu kunye ne-1.10 mass% okanye ngaphantsi kwe-carbon, i-0.05 mass% okanye ngaphezulu nangaphantsi kwe-0.3 mass% ye-silicon, i-0.10 mass% okanye ngaphezulu kunye ne-0.50 ubunzima% 11 A yeendlela zogqatso lweringi yangaphandle kunye ne-12 A yeendlela zomdyarho zangaphakathi ezingumphezulu oqulathe intsimbi equlathe le manganese ilandelayo, 1.30 ubunzima% okanye ngaphezulu, kunye ne-2.00 ubunzima% okanye ngaphantsi, kwaye iqulathe intsimbi. iqulethe intsalela yentsimbi kunye nokungcola, kunye nokudibana namanye amalungu.Kwaye i-avareji yoxinaniso lwenitrogen kummandla womphezulu umaleko 11B, 12B, kunye 13B eziyimimandla ngaphakathi kubunzulu 20 μm ukusuka ibhola rolling umphezulu 13A yi 0.2% ubunzima okanye ngaphezulu kunye 0.7% ngobunzima okanye ngaphantsi, kwaye kumphezulu. imimandla umaleko 11B, 12B, 13B, 5 okanye ngaphezulu carbides kunye ububanzi 0.5 micrometer okanye ngaphantsi zikhona nge-100 micrometer.
