Ukuchaneka kokuchaneka kuqulathe ukuchaneka nokujikeleza ukuchaneka komlinganiselo wokuchaneka yiprojekthi enyukayo kwishafti, ibandakanya phakathi kwedayamitha, ngaphandle kwedayamitha, ububanzi, ukunyamezelwa kobungakanani be-chamfer okanye ixabiso elivumelekileyo. Umsesane wangaphakathi kunye nendandatho yangaphandle ye-radial swing kunye ne-axial runout, Icala lendandatho yangaphakathi kunye ne-diameter yangaphandle ye-perpendicularity tolerance range.Ukuthwala ibakala lokuchaneka ukusuka kwibanga eliqhelekileyo ukuya kwi-0 ukuya kwi-6, i-5, ibakala lesi-4 kunye ne-2 yebakala, ngokulandelelana, ngezantsi kuthelekiso lwetafile phakathi kweklasi ye-preeision ye-china GB ye-307 yomgangatho ochanekileyo, i-5 ye-precision grade grade, i-5 ye-precision ye-grade 307 Amanqanaba 4 no-2 amabakala amane. 

Iringi yangaphandle i-11, i-inner ring 12, kunye ne-13 yebhola enamacandelo athweleyo yi-0.95 mass% okanye ngaphezulu kunye ne-1.10 mass% okanye ngaphantsi kwe-carbon, 0.05 ubunzima% okanye ngaphezulu kwaye ngaphantsi kwe-0.3 mass% ye-silicon, i-0.10 ubunzima% okanye ngaphezulu kunye ne-0.50 ubunzima be-11 ringways ngaphandle kunye nogqatso lwangaphakathi lwe-11 A. umphezulu oqulathe intsimbi equlathe le manganese ilandelayo, 1.30 ubunzima% okanye ngaphezulu, kunye ne-2.00 ubunzima% okanye ngaphantsi, kwaye iqulathe intsimbi eshiyekileyo kunye nokungacoceki, kunye noqhagamshelwano namanye amacandelo. Kwaye i-avareji yoxinaniso nitrogen kummandla womphezulu umaleko 11B, 12B, kunye 13B leyo imimandla ngaphakathi kubunzulu 20 μm ukusuka ibhola rolling umphezulu 13A yi 0.2% ngobunzima okanye ngaphezulu kunye 0.7% ngobunzima okanye ngaphantsi, kwaye kwimimandla umaleko umphezulu 11B, 12B, 13B, 13B, 13B imitha engaphezulu okanye ngaphantsi kwe imitha ye-carbides 5 ekhoyo okanye ngaphantsi kwe-carbides engaphantsi kwe-5. I-100 micrometer.
