Ma lalo o kekahi haawe, ka helu o nā hoʻololi a i ʻole hola e ahali anakapa ʻia nā ʻike ma mua o ka puka ʻana o ka luahali anaola.
Ua wehewehe ʻia ke ola o ka bearing wili e ka helu o nā kipi (a i ʻole nā hola o ka hana ma kekahi wikiwiki): i loko o kēia ola, pono e loaʻa i ka bearing ka pōʻino luhi mua (spalling a chipping) ma kekahi o kāna mau apo apo a i ʻole nā mea ʻōwili. Eia naʻe, inā ma nā hoʻokolohua hoʻokolohua a i ʻole ka hoʻohana maoli ʻana, hiki ke ʻike maopopo ʻia ke ola maoli onā bearingsme ka hiʻohiʻona like ma lalo o nā kūlana hana like he ʻokoʻa loa.

In order to determine the standard of bearing life, the bearing life and reliability are related.
