No laila, kūpono loa kēia mau bearings no nā wili mīkini kahi e pono ai i ka hoʻonohonoho bearing ke hoʻokipa i nā ukana radial kaumaha a me nā wikiwiki kiʻekiʻe, ʻoiai e hāʻawi ana i kahi kiʻekiʻe o ka ʻoʻoleʻa, ʻoi aku ka kūpono o nā bearings lālani pālua no nā ukana kaumaha.

ʻElua mau ʻano o nā bearings cylindrical lālani pālua: ka cylindrical inner bore a me ka conical inner bore (ʻo ke code hope bearing me K). Hiki i ka lua conical i loko ke hana i ka hana o ka hoʻoponopono liʻiliʻi o ka ʻae, a hiki ke hoʻomaʻalahi i ke ʻano o ka hāmeʻa hoʻonoho a maʻalahi i ka hoʻonohonoho ʻana a me ka wehe ʻana.

ʻO nā bearings wili cylindrical lālani pālua i hoʻohana pinepine ʻia i kēia mau ʻano: NN series, NNU series, a me NNF series. Nā hoʻomanawanui: SP, UP, SP a me UP no 1:12 tapered bore.

NN3012KTN/SP ʻOi aku ka pololei o ka wili wiliwili lālani pālua o ka NN3012KTN/SP ka wehewehe ʻana o ka hope
K:ʻO ka lua i hoʻopaʻa ʻia, Taper 1:12
TN: Hale paʻa PA66
SP: Papa Kikoʻī Kūikawā no nā Bearings Mea Hana Mīkini: Pololei Ana ma kahi o P5, Pololei Holo ma kahi o P4

ʻO nā bearings roller cylindrical super-precision i hōʻike ʻia e:
Ka hiki ke wikiwiki kiʻekiʻe
Ka hiki ke hāpai i ka ukana radial kiʻekiʻe
ʻOʻoleʻa kiʻekiʻe
Haʻahaʻa ka haʻalulu
Ke kiʻekiʻe ʻāpana haʻahaʻa
