ʻAʻole hiki ke hoʻokaʻawale ʻia ka maikaʻi o ka bearing a me ke koho ʻana o nā mea i ka wā o ka hoʻohana ʻana i ka bearing.No laila, pono mākou e koho i nā mea kiko'ī o ka halihali e like me nā pono kiko'ī o ka mea kūʻai.No laila he aha nā waiwai o ka mea hao hao?Ma muli o ka hoʻomaopopo ʻana, ua helu ʻia nā hiʻohiʻona hana o ka lawe ʻana i nā mea kila.

Pono e loaʻa i ke kila amo nā waiwai penei:

1. High contact fatigue ikaika.

2. Ke kū'ē abrasion kiʻekiʻe.

3. Ka palena elastic kiʻekiʻe a me ka ikaika hua.

4. ʻO ka paʻakikī kiʻekiʻe a kūlike.

5, kahi paʻakikī hopena.

6. Ke kūpaʻa maikaʻi.

7, maikaʻi corrosion inhibition hana.

8. Hana maikaʻi kaʻina hana.

ʻO ke kohoʻana i nā mea hao hao e pono ai ke kūʻai kūikawā.No ka lawe ʻana i nā mea hana ma lalo o nā kūlana kūikawā, e like me kā lākou mau koi kikoʻī, pono lākou e loaʻa nā waiwai kūikawā i kūpono i ko lākou mau kūlana, e like me: ke kiʻekiʻe kiʻekiʻe o ka mahana, ka haʻahaʻa haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion, Anti-radiation, anti-magnetic a ʻano ʻano ʻē aʻe.
