ʻEhā lālani Cylindrical Roller Bearings
Nā hiʻohiʻona
Hiki i nā bearings cylindrical ʻehā lālani ke kū i nā ukana radial nui a me nā ukana hopena, akā ʻaʻole hiki ke kū i nā ikaika axial. Loaʻa iā lākou ka pololei machining kiʻekiʻe a kūpono no ka hana kiʻekiʻe. No ka mea, ʻaʻohe iwi ʻaoʻao o ke apo i loko, hiki ke hoʻokomo ʻia nā ʻāpana apo o loko a me waho.
ʻO kēia ʻano o ka bearing e hoʻomaʻamaʻa i ka hoʻololi pinepine ʻana i nā ʻano ʻōwili like ʻole a hiki ke hoʻohana ʻia i nā ʻano wili anuanu a wela. Ma muli o kāna mau mea maikaʻi o ka nui o ka radial bearing capacity, kiʻekiʻe rotation pololei, a me ka maʻalahi o ka hoʻonohonoho ʻana a me ka wehe ʻana, ʻo ia ka koho mua no nā ʻano like ʻole o ka rolling mill roll bearings.
Ma hope o ka paʻi ʻia ʻana o ke apo i loko o ke anawaena o ka ʻōwili, hiki ke hoʻoheheʻe ʻia ka ʻili o ka raceway i loko a me ka ʻili o ka ʻili i ka manawa like, kahi mea e pono ai ka hoʻomaikaʻi ʻana i ka pololei o ka ʻōwili ʻana, a hiki ke hoʻoponopono manuahi ʻia ka ʻae ʻana o ka bearing.
FC: apo lua waho, apo i loko hoʻokahi, apo i loko me ka iwi ʻaoʻao ʻole
FCD: apo lua waho, apo lua loko, apo i loko me ka iwi ʻaoʻao ʻole
FCDP: ʻelua apo i waho, hoʻokahi wale nō iwi ʻaoʻao waena o ke apo o waho akā he iwi ʻaoʻao palahalaha, apo lua loko, ʻaʻohe iwi ʻaoʻao o ke apo o loko.

Hoʻohana nui ʻia kēia ʻano o ka bearing ma nā ʻōwili hana a i ʻole nā ʻōwili kākoʻo o nā wili wili anuanu a wela, nā mīkini blanking a me nā mīkini ʻē aʻe, a hiki ke hoʻohana ʻia i nā lako ʻē aʻe.
ʻEhā lālani huila huila cylindrical:
Ka nui anawaena o loko: 90mm~1480mm
Ka nui anawaena o waho: 140mm~1850mm
Laulā nui laula: 70mm~1100mm
ʻO ka hoʻomanawanui: ʻO ka pololei o ka huahana he papa maʻamau, P6 grade, P5 grade, a me nā huahana P4 grade hiki ke hana ʻia inā loaʻa i ka mea hoʻohana nā koi kūikawā.
Hoʻomaʻemaʻe Radial
ʻO ka huahana maʻamau o ʻehā lālani cylindrical roller bearing he 3 sets of clearance, a loaʻa pū kekahi pūʻulu hoʻomaʻemaʻe.
Hiki ke hana ʻia nā bearings me ka radial clearance e like me nā koi o ka mea hoʻohana.
hale kiai
Hoʻohana nui ʻia ka lālani ʻehā cylindrical roller bearing i ka hale keleawe i hana ʻia i ke kaʻa, a pono e hoʻohana ʻia ka hale paʻa paʻa i hana ʻia no ka nui nui.
