Huina Po'o Po'oʻO nā huila i hoʻohana ʻia i nā ʻāpana ʻōwili e kūʻē i nā pōpō i nā bearings pōpō. No laila, ʻoi aku ka nui o nā huila (linear) pili me ke apo o waho a ke hāʻawi nei i nā ukana ma kahi ākea ākea.

Ma hope mai, loaʻa iā lākou ka mana hoʻouka radial kiʻekiʻe a kūpono i nā wikiwiki kiʻekiʻe.He kiʻekiʻe ka rigidity radial nā bearings cylindrical ʻelua lālani a hoʻohana mua ʻia no nā mea mīkini pololei.

ʻO nā ʻano o ka huila cylindrical:

Nā huila huila lālani ʻelua: NNU moʻo.
ʻEhā lālani huila huila pōʻaiapili: FC moʻo.
ʻO ka lālani hoʻokahi e hoʻopiha piha ana i ka huila pahu pahu: SL18 series, SL 19 series.
ʻO ka lālani pālua piha piha i ka huila huila cylindrical: SL01 series, SL02 series, SL18 series.
