Bari mu fara fahimtar gajarta dogon radius da gajeriyar radius.
Dogon radius bakin karfe gwiwar hannu: LR/EL/1.5D;
Short radius bakin karfe gwiwar hannu: SR/ES/1D;
Radius da aka ambata anan yana nufin radius na lanƙwasa bakin gwiwar bakin karfe. Dogon radius na gwiwar hannu yana nufin radius na curvature daidai da sau 1.5 na waje diamita na bututu, wato, R=1.5D. Gajeren gwiwar hannu yana nufin radius na curvature daidai yake da diamita na waje na bututu, wato R=1D.
Dogayen gwiwar radius sune aka fi amfani da su. Ana amfani da gajerun maginin radius ne kawai lokacin fuskantar wasu yanayi na musamman, kamar rashin isasshen wurin shigarwa.
Daga hangen nesa na wasan kwaikwayon, ƙimar lalacewa na madaidaicin radius mai tsayi bai kai na gajeriyar radius ba, ƙarfin lalata kuma yana raguwa sosai, kuma juriya kuma ya fi ƙanƙanta, wanda ya fi madaidaicin madaidaicin radius. Inda matsi ya yi girma ko kuma yawan kwararar ruwa ya yi yawa, za a yi amfani da madaidaicin radius mai tsayi. Idan buƙatun juriya na ƙaƙƙarfan bututun isar da bututun isar da sako sun yi tsauri, za a yi amfani da ƙwanƙwaran radius mafi girma. Ana amfani da gajerun radius gabaɗaya a cikin ruwa mai ƙarancin ƙarfi ko kuma inda akwai ƙuntatawa akan shigar da gwiwar hannu.

The lissafin dabara don cibiyar tsawo na bakin karfe gwiwar hannu: diamita * mahara Alal misali, daidai maras muhimmanci diamita na m diamita 219mm ne 200, sa'an nan tsakiyar tsawo na daidai dogon radius bakin karfe gwiwar hannu ne 200*1.524=304.8, kai. 305;
Tsayin tsakiyar madaidaicin gajeriyar radius bakin karfe gwiwar hannu shine 200*1.015=203
Za'a iya duba takamaiman ma'auni na bakin karfen gwiwar hannu ta danna nan.
