(1) Nā huila ʻōwili me nā koi haʻahaʻa haʻahaʻa

ʻO nā bearings maʻamau i hana ʻia ma Kina, ʻo kekahi lālani radial ball bearings a me ka pōkole cylindrical roller bearings he mau ʻano haʻahaʻa haʻahaʻa i hoʻohana ʻia i nā bearings mana.Ma waena o lākou, aia nā ʻano ʻano o nā bearings pōpō mai ke anawaena o loko φ2.5mm a φ60mm me ʻekolu suffixes Zl, Z2 a me Z3, e pili ana i ʻekolu mau koi haʻahaʻa haʻahaʻa.ʻEwalu ʻano o ka huila huila mai N309 a i N322 i loaʻa pū kekahi.Hana ʻia nā ʻano like ʻole e like me nā kūlana haʻahaʻa haʻahaʻa.

Hiki ke hoʻohana ʻia kēia mau bearings i nā mīkini ʻē aʻe me nā koi haʻahaʻa haʻahaʻa, a ʻoi aku ke kumukūʻai.Inā hiki iā lākou ke hoʻokō i nā koi i ke ʻano a me ka nui, e hoʻāʻo e hoʻohana i kēia mau ʻano ʻelua o nā bearings haʻahaʻa haʻahaʻa.

(2) E hoʻohana i nā bearings mālie

Ke hiki ʻole ke hoʻohana ʻia nā ʻano haʻahaʻa haʻahaʻa haʻahaʻa i luna, hiki ke hoʻohana ʻia nā bearings me ka haʻahaʻa haʻahaʻa.ʻO ke kumu hoʻohālikelike kikoʻī penei:

1) He haʻahaʻa ka walaʻau o nā bearings ma mua o nā huila wili, a ʻoi aku ka haʻahaʻa o ka (friction) o nā bearings me ka liʻiliʻi o ka hoʻoheheʻe ʻana ma mua o ka poʻe me ke ʻano heʻe;

2) He haʻahaʻa loa ka walaʻau o ka hale paʻa paʻa ma mua o ka hali ʻana o ka hale paʻa;ʻoi aku ka haʻahaʻa o ka hali ʻana o ka hale paʻa paʻa ma mua o ka hali ʻana o nā hīnaʻi ʻelua ma luna;mānoanoa ka helu o nā pōpō, mānoanoa ke apo o waho, a haʻahaʻa ka walaʻau.

3) ʻO nā bearings kiʻekiʻe, ʻoi aku ka nui o ka poʻe i ʻoi aku ka pololei o nā mea ʻōwili, ʻoi aku ka haʻahaʻa o ka leo ma mua o nā bearings haʻahaʻa haʻahaʻa.

4) ʻOi aku ka liʻiliʻi o ka leo o nā bearings liʻiliʻi ma mua o nā bearings nui.
