Don cimma $360^{\circ}$ lamba, diamita $D_g$ dole ne ya dace daidai da ƙirar zobe. Don zoben shaft, ID ɗin kyauta na zoben koyaushe yana ƙanƙanta da diamita na tsagi don tabbatar da dacewa da 'danko'. Lissafin shine $D_{kyauta} = D_g - (Cling)$, inda 'Cling' shine yawanci $1%$ na diamita. Don zobe mai ƙyalƙyali, OD ɗin kyauta ya fi girma fiye da diamita na tsagi. Idan tsagi ya yi zurfi sosai, zoben ba zai cika faɗaɗawa/kwagila ba, yana haifar da tazara a tallafin $360^{\circ}$. Wannan rata yana haifar da matsananciyar damuwa akan bangon tsagi. Dole ne injiniyoyi su ƙayyade faɗin tsagi $W_g$ wanda shine $10-20 \%$ mafi faɗi fiye da matsakaicin kaurin zoben $T$ don ba da izinin shigarwa na 'winding' da motsi axial.
