Ukuthwala isinyithi somgubo senziwe ngomgubo wesinyithi kunye nezinye izinto ezichasene ne-antifriction umgubo ocinezelwe, ufakwe i-sintered, iplastiki kwaye ifakwe emanzini.Inesakhiwo esinemingxuma.Emva kokungeniswa kweoli eshushu, iipores zizaliswe ngeoli yokuthambisa.Kwinkqubo yokusebenza, isinyithi kunye neoli zifudumala kwaye zandiswa, kwaye ioli ikhutshwe kwiipores.Umphezulu wokukhuhlana uyathanjiswa.Emva kokuba ukuthwala kupholile, ioli iphinda ifakwe kwi-pores.

Iibheringi ze-powder metallurgy azikwazi ukuthanjiswa ixesha elide.

I-porosity ephezulu yeebheringi ze-metallurgy yomgubo, ukugcinwa kweoli eninzi, kodwa i-pores eninzi, amandla aphantsi.

Iibheringi ezinjalo zihlala zikwimeko edibeneyo yokuthambisa, ngamanye amaxesha inokwenza i-lubrication yefilimu encinci.Zihlala zisetyenziselwa ukuncedisa umthwalo onzima kunye nokukhanya kunye nesantya esisezantsi se-oyile yokuthambisa.

Ngokweemeko ezahlukeneyo zokusebenza, iibheringi ze-powder metallurgy kunye nomxholo weoli ohlukeneyo zikhethwa.Xa umxholo weoyile umkhulu, unokusetyenziswa phantsi kweoyile yokuthambisa eyongezelelweyo kunye nomthwalo ophantsi.Umxholo weoli ungasetyenziselwa phantsi komthwalo onzima kunye nesantya esiphezulu.I-graphite ephethe umgubo wesinyithi wesinyithi inokuphucula ukhuseleko lokuthwala ngenxa ye-lubricity ye-graphite ngokwayo.Ukungalungi kwayo kukuba amandla aphantsi.Ngaphantsi kwemeko yokungabikho kwe-corrosion, inokuqwalasela ukukhethwa kwexabiso eliphantsi kunye namandla.Isiseko sesinyithi somgubo wesinyithi esineqondo eliphezulu siphezulu, kodwa ukuqina kwentamo ye-shaft ehambelanayo kufuneka kuphuculwe ngokufanelekileyo.
