Ukuxabana ngaphakathiukufowunakukuxinana phakathi kweentsimbi ezimbini zobume kunye neepropathi (izabelo), phakathi kwentsimbi ethambileyo (Umsebenzi wensimbi) kunye nentsimbi enzima (die). Kwimeko leyo ngaphandle kwe-qubrication, kukungqubana kweentlobo ezimbini zensimbi yentsimbi; Phantsi kwemeko ye-yebricetion, ukungqubana konxibelelwano phakathi kwefilimu ye-oxide kwimigangatho emibini yentsimbi kunye nendawo enobunkunkqele, kunye nokuntywila phakathi komphezulu we-oxpres, engekabinamsebenzi onamandla, kunye nokuxinana phakathi kwendawo enobunkunkqele kunye nomphezulu we-die kunye nendawo yokuthambisa (yoqhagamshelwano) iyanda.

Ngenxa yeempawu ezixineneyo phakathi kwento engenanto kunye nendawo yokuqhawula umtshato kwiInkqubo yokuGcina, ezi ziphumo zilandelayo ziya kukhokelela:

Ingabonwa ukuba ukuxabana likrele elingena mbiniUkuveliswa kwemveliso, eneengenelo kunye nezinto ezingalunganga. Ke ngoko, ukungqubana kwinkqubo yefomati kufuneka kulawulwe ngokungqongqo ukuqinisekisa inkqubo eqhelekileyo yokufota.
