ʻO nā bearings kahi ʻāpana koʻikoʻi o nā mea hana mechanical.I loko o ka spindle motorized, ʻoi aku ka nui o ka hana hilinaʻi o nā bearings, e pili pono ana i nā hōʻailona hana o ka mīkini mīkini.Ma kahi o ka hoʻokō ʻana o ka bearing e pili ana i kāna mea ponoʻī, ʻo ke koho o ka lubrication a me ke ʻano hoʻoluʻu he mea nui loa.No ka hoʻokō ʻana i ka ʻoki kiʻekiʻe o nā mīkini mīkini, ʻo ka mea mua, pono ke kiʻekiʻe ka wikiwiki o ka rotational o ka shaft.ʻO ka māmā holo kiʻekiʻe e pono ai ka hana hali paʻa.He mea koʻikoʻi ka lubrication e hōʻoia i ka hana o ka bearing.Ke hoʻohana nei i ka ʻaila hinu a me ka lubrication kinoea, hiki ke hoʻomaʻamaʻa maikaʻi ʻia ka bearing, ʻoi aku ka paʻa o ka spindle motorized, a loaʻa iā ia kahi kuhikuhi hana maikaʻi.

Ma waena o nā mea e pili ana i ka wikiwiki a me ka hana o ka electrospindle, pili ka deformation thermal i ka lubrication.ʻO ke kumu wela o loko o ka spindle uila mai ʻelua ʻaoʻao: ka wela i hana ʻia e ke kaʻa i kūkulu ʻia a me kahali milo.

ʻO ka wela o kahali milohiki ke hoʻoholo ʻia ma ka hoʻohana ʻana i ka lubrication aila a me ke kinoea.ʻAʻole nui ka nui o ka haʻi ʻana o ka spindle uila, a ʻaʻole pono ka nui o ka aila lubricating e lubricate.Inā hoʻohanaʻia ka nui o kaʻaila lubricating no ka lubrication invasive i keʻano o ka lubrication maʻamau,ʻaʻole i'ōleloʻia keʻano, no ka meaʻaʻole hiki ke hāʻawi i ka lubrication maikaʻi, a e pau ka nui o kaʻaila hinu.I ka holo mau ʻana o ka ʻaila lubricating, e piʻi aʻe ka mahana o ka aila ma muli o ka friction ma waena o nā molekele aila, a ʻaʻole kūpono ka piʻi ʻana o ka mahana i ka hana o ka spindle uila.No laila, koho ʻia ka ʻaila hinu a me ke kinoea o nā bearings.Hiki i kēia ʻano micro-lubrication ke hōʻemi i ka hāʻawi ʻana i ka ʻaila lubricating, ʻaʻole ia e hoʻopau wale i ka wela i hana ʻia e ka friction o ka nui o nā molekole aila, akā ʻoi aku ka maikaʻi o ka lubrication hopena.Hoʻopili ʻia ka bearing me ka ʻaila a me ke kinoea, a ʻo ka hāʻawi ʻana i ka aila e hahai i ke kumu o ka ʻaila liʻiliʻi i ka manawa.I kēlā me kēia manawa, hoʻolako nui ʻia ka aila ma kahi liʻiliʻi liʻiliʻi, a hoʻonui ʻia ke alapine o ka aila e hoʻokō i nā koi lubrication o ka bearing.ʻO kēia ʻano lubrication ka mea e hoʻolele ai ka ea lubricating i ke kiʻi ʻaila lubricating i ka ʻili friction, hoʻokani piha ka ʻaila lubricating i ka hana o ka lubrication, a hiki i ka ea paʻa ke lawe aku i ka wela i hana ʻia e ka friction a pāʻani i kahi hana hoʻomaha.

ʻO ke koho ʻana i ka ʻaila hinu a me ka lubrication kinoea hiki ke hōʻuluʻulu i nā pono penei:

1. He haʻahaʻa ka nui o ka aila lubricating, mālama i nā kumukūʻai,

2. He maikaʻi ka hopena lubrication, e hōʻoiaʻiʻo ana i ka hana hoʻolālā o ka spindle uila.

3. Hiki i ka ea compressed ke lawe i ka wela i hana ʻia i loko o ka milo uila, me ka pale pono ʻana i ke ʻano o ka bearing ma muli o ka wela.

4. ʻO ke kaomi maikaʻi i loko o ka bearing e pale i ka komo ʻana o nā mea haumia.
