Idayamitha yangaphandle yombhobho ongenamthungo oqengqelekayo ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-200mm. Ububanzi obungaphandle bombhobho wentsimbi ongenamthungo obandayo bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. Idayamitha yangaphandle yombhobho obhityileyo unokufikelela kwi-5mm kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm.

Umbhobho wentsimbi esetyenziswa ngokubanzi ingenamthungo yenziwe nge-10, 20, 30, 35, 45 kunye nezinye ezikumgangatho ophezulu we-carbon bonded steel 16Mn, 5MnV kunye nezinye i-alloy ephantsi yolwakhiwo lwentsimbi okanye i-40Cr, 30CrMnSi, 45Mn2, 40MnB kunye nezinye intsimbi edibeneyo ye-carbon ephantsi okanye enye i-2 epholileyo. umbhobho wokuvelisa ongenamthungo usetyenziswa ikakhulu kumbhobho we-fluid.45, 40Cr kunye nenye intsimbi yekhabhoni ephakathi eyenziwe ngombhobho ongenamthungo ukwenza iindawo ezingoomatshini, njengeemoto, iitrektara ezigxininisiweyo.Ukusetyenziswa ngokubanzi kombhobho wentsimbi ongenamthungo ukuqinisekisa ukuba amandla kunye novavanyo olucaba.Imibhobho yentsimbi egotyiweyo ihanjiswa kwindawo eshushu eqengqelekayo okanye ephathwa ngubushushu.
