Powder yokunyibilikisa isinyithi yenziwa ngomgubo wentsimbi kunye nezinye izinto ezichasayo zomgubo ocofa, sintered, iplastiki kunye nokuntywila. Inesakhiwo sokungena. Emva kokungena kweoyile eshushu, ii-pores zizaliswe ngeoyile yokuthambisa. Kwinkqubo yokusebenza, isinyithi kunye neoyile ziyafudunyezwa kwaye zandiswe, kwaye ioyile iyaxovulwa ngaphandle kwemingxunya. Umphezulu wokuxubana uthambisile. Emva kokuba into epholileyo ipholile, ioyile iyabuyiselwa emingxunyeni.

Powder yokunyibilikisa isinyithi ayikwazi ukuthambisa ixesha elide.

I-porosity ephezulu ye-powder metallurgy bearings, ukugcinwa kweoyile ngakumbi, kodwa ii-pores ezingakumbi, amandla asezantsi.

Iibheringi ezinjalo zihlala zikwimo yokudibanisa ukuthambisa, ngamanye amaxesha zinokwenza ukuthambeka kwefilimu encinci. Zihlala zisetyenziselwa ukongeza umthwalo onzima kunye nokukhanya kunye nesantya esiphantsi seoyile yokuthambisa.

Ngokweemeko ezahlukeneyo zomsebenzi, i-powder metallurgy iibheringi ezinomxholo weoyile ezahlukeneyo zikhethiwe. Xa umxholo weoyile mkhulu, unokusetyenziswa ngaphandle kokuthambisa ioyile kunye nomthwalo ophantsi. Umxholo weoyile unokusetyenziswa phantsi komthwalo onzima kunye nesantya esiphezulu. Grafayithi ethwele umgubo yokunyibilikisa isinyithi unokuphucula ukhuseleko lokuthwala ngenxa yokuthambisa kwegraphite uqobo. Ububi bayo kukuba amandla asezantsi. Ngaphantsi kwemeko yokungabikho komhlwa, inokujonga ukukhethwa kwexabiso eliphantsi kunye namandla. Isiseko sesinyithi somgubo wokunyibilikisa isinyithi ophethe isidanga esiphakamileyo siphezulu, kodwa ubunzima bentsimbi ehambelana nayo kufuneka buphuculwe ngokufanelekileyo.
