ʻO nā hoʻāʻo e hoʻololi i ka hoʻoheheʻe ʻana me ka hoʻopili ʻana i ka ʻōwili ʻia i ʻike ʻia ua leʻaleʻa ʻia i ka wā prehistoric.ʻO ka pā kiʻi he kiʻi pena ma ʻAigupita.Ke lawe ʻia nei kekahi pōhaku nui ma nā lāʻau ʻōwili i waiho ʻia ma lalo.ʻO ke ʻano o ka lawe ʻia ʻana o kēlā mau lāʻau i hoʻohana ʻia i ka ʻaoʻao mua e hōʻike pololei ana i ke ʻano o ka hana ʻana o ka ʻenekini holo kaʻa i loko o nā bearings linear motion i kēia lā.
ʻOiai ke ʻike ʻia nei nā huila huila laina i ko lākou kumu hoʻi i ka wā kahiko, ʻaʻole lākou i maʻalahi i ka hoʻohana maʻamau ma ke ʻano he mechanical element a hiki i ka hoʻomaka ʻana o ke kenekulia 20, i ka wā i hoʻohana ʻia ai kēlā mau mea ʻōwili i nā pōpō kila no kā lākou neʻe laina pololei a maʻalahi. ua maʻalahi ka hoʻohana ʻana i nā mīkini pololei.
ʻO ka mīkini kumu o ka mea ʻōwililaina laina lainaUa hoʻokumu ʻia i ka makahiki 1946 i ka wā i kūʻai ʻia ai kahi hui ʻAmelika, ʻo Thomson, i nā ʻōpala pōlele (he ʻano pōlele hou ʻana).Hiki ke ʻike ʻia ke kumu o nā alakaʻi laina o kēia lā (rolling units with rails) ma kahi patent i hāʻawi ʻia ma Farani i ka makahiki 1932.ʻO kēia patent, ʻoiai e hoʻopili ana i nā hana koʻikoʻi āpau o nā alakaʻi laina, pono mau e kali no nā makahiki he mau makahiki ma mua o kā lākou noi noi ma ka mākeke.I loko o ia manawa, ua kūʻai kūʻai ʻia kekahi mau ʻāpana mīkini e hoʻohana ana i nā mea ʻōwili e like me nā pōlele a i ʻole nā splines.Ua lawe ʻia mai i ka mākeke nā ʻano ʻano like ʻole o nā puʻupuʻu pōleʻa (linear ball bearings), me nā bearings ʻano hāmama.I kēia manawa, nui nā mea hou a me nā hoʻomaikaʻi o nā ʻano like i hana ʻia i kaalakai laina.
mākou,PYG-ʻO Zhejiang Pengyin Technology Development Co., LTD, kahi ʻoihana ʻenehana kiʻekiʻe e kālele ana i ka noiʻi a me ka hoʻomohala ʻana i nā ʻāpana kikoʻī laina laina a me ka hoʻolālā hou ʻana no nā makahiki ʻoi aku ma mua o 20. ʻO nā lako hana, hoʻolauna i nā lako kikoʻī kiʻekiʻe o ka honua a me ka ʻenehana hou, hiki iā PYG ke hana nui i nā laina laina kiʻekiʻe kiʻekiʻe me ka pololei o ka sliding ma lalo o 0.003 mm.
