Moyo wautumiki wa zitsulo zodzipaka mafuta zodzipangira mafuta nthawi zambiri zimatsimikiziridwa ndi kuchuluka kwa mafuta mu pores.

Ukadaulo wazitsulo zaufa pakali pano ndi imodzi mwa njira zomwe zimatha kuchepetsa kuwonongeka kwa zinthu zomwe zingatheke, molingana ndi mlingo wapamwamba kwambiri, komanso mtengo wotsika kwambiri, imodzi mwa njira zopangira magawo ovuta.

The dzenje ufa zitsulo bushing kwa magalimoto ndi chimodzi mwa magawo oyambirira opangidwa ndi luso zitsulo ufa, ndipo akadali misa-opangidwa ndi luso limeneli.Ubwino waukulu wa zitsamba zopanda pake ndikuti zimatha kulowetsedwa ndi mafuta opaka mafuta osagwirizana ndi utomoni kuti athandizire tchire izi siziyenera kupakidwa mafuta pa moyo wonse wa unsembe.

Pamene tsinde likuyenda mu porous bushing, mafuta opaka mafuta omwe amalowa mu pores amakwera pamafuta.Pamene shaft imayima, chifukwa cha ntchito ya capillary, mafuta odzola amayamwa mmbuyo mu pores.Ngakhale kuti n'zotheka kuti ma bere opangidwa ndi mafuta apange filimu yathunthu yamafuta, nthawi zambiri, kubereka kwamtunduwu kumakhala mumkangano wosakanikirana ndi filimu yosakwanira yamafuta.

Ufa zitsulo zitsulo chimagwiritsidwa ntchito kwambiri mu: mafakitale magalimoto, zida magetsi, makampani galimoto, galimoto ndi njinga zamoto makampani, zipangizo muofesi, makampani zipangizo kunyumba, mankhwala digito, makina nsalu, ma CD ndi zida zina zamakina.
