Hōʻike huahana:

He ʻano ʻano huila huila ʻo Needle roller bearing e hoʻohana ana i nā wili cylindrical lahilahi e like me nā nila.ʻOi aku ka lōʻihi o nā huila huila maʻamau ma mua o ko lākou anawaena, akā ʻoi aku ka maʻamau o nā huila nila i ʻehā mau manawa lōʻihi ma mua o ko lākou anawaena.[1]E like me nā bearings a pau, hoʻohana ʻia lākou e hōʻemi i ka friction o kahi ʻili ʻili

Ke hoʻohālikelike ʻia i nā bearings pōpō a me nā bearings roller maʻamau, ʻoi aku ka nui o ka ʻili o ka nila i ka hui ʻana me nā heihei, no laila hiki iā lākou ke kākoʻo i kahi ukana ʻoi aku.ʻOi aku ka lahilahi, no laila makemake lākou i ka liʻiliʻi ma waena o ke axle a me ka hale a puni.

Hoʻohana nui ʻia nā bearings i nā ʻāpana kaʻa e like me nā pivots rocker arm, pumps, compressors, a me nā hoʻouna.ʻO ke kumu hoʻokele o ka kaʻa kaʻa kaʻa hope he ʻewalu aʻoi aku ka liʻiliʻi o nā bearings nila (ʻehā ma kēlā me kēia hui U) a ʻoi aku ka nui inā lōʻihi loa, a i ʻole e hana ana ma nā pali pali.
