Hoʻokumu ʻia ke kumu hana o nā bearings plain spherical i ka hoʻolālā kūʻokoʻa o kā lākou hana. Ma o ka laulima o ka lima o waho, ka lima o loko, a me ka hui poepoe, loaa ia lakou ke kaulike ma waena o ka hiki- amo a me ka ma'alahi.
I nā mīkini, hoʻohana pinepine ʻia nā bearings spherical plain e kū i nā ukana paʻakikī a me nā neʻe, e like me nā ʻōnaehana hoʻokuʻu kaʻa. Hāʻawi lākou i ka ikaika haʻahaʻa -ʻoiai e pale ana i ka haʻalulu, luhi, a me ka ʻuʻuku.
Eia kekahi, hoʻohana nui ʻia nā bearings spherical i nā ʻōnaehana mana mechanical, e like me nā mana mechanical engine a me nā shaft kaʻa kaʻa. ʻO kā lākou hoʻolālā noʻonoʻo e hōʻemi pono i ka haʻalulu a me ka walaʻau, e hōʻoia i ka maʻalahi, paʻa, palekana, a ʻoi aku ka hilinaʻi o ka hana mechanical.
