ʻO Cylindrical Roller bearings kekahi o nā bearings rolling, i hoʻohana nui ʻia i nā mīkini hou. Ke hilinaʻi nei ia i ka hui ʻana ma waena o nā mea nui e kākoʻo i nā ʻāpana ʻōwili. hoʻomaka, kiʻekiʻe rotation pololei a me ka maʻalahi koho.
ʻO ka huila cylindrical a me ka raceway he mau laina pili laina.ʻO ka mana hoʻouka nui, e halihali ana i ka ukana radial.He liʻiliʻi ka friction ma waena o ka mea ʻōwili a me ka ʻaoʻao paʻa o ka ferrule, kūpono ia no ka hoʻololi kiʻekiʻe.E like me ka ferrule i ka ferrule paa i ka lihi a i ole, hiki ke maheleia i hookahi lalani cylindrical huila huila e like me Nu, NJ, NUP, N a me NF, a papalua laina cylindrical huila huila e like me NNU a me NN.ʻO ka bearing kahi ʻano hoʻokaʻawale o ke apo i loko a me ke apo o waho.
