Os rolamentos cil\u00edndricos de quatro carreiras da NSK s\u00e3o projetados especificamente para acomodar cargas extremamente pesadas e de impacto e funcionar com suavidade e precis\u00e3o nos cilindros de encosto dos suportes do laminador. Em condi\u00e7\u00f5es operacionais particularmente adversas, o a\u00e7o Super-TF de longa vida da NSK oferece durabilidade substancialmente maior para neutralizar a carga de rolamento pesada e a alta probabilidade de comprometimento da lubrifica\u00e7\u00e3o do rolamento devido \u00e0 contamina\u00e7\u00e3o.<\/p>\n

Dispon\u00edvel em uma grande variedade de tipos de projetos com op\u00e7\u00f5es de gaiola de alto desempenho e fabricados para toler\u00e2ncias de precis\u00e3o, os rolamentos cil\u00edndricos de quatro carreiras da NSK s\u00e3o otimizados para oferecer alta capacidade e alta precis\u00e3o para a fabrica\u00e7\u00e3o ininterrupta e precisa de chapas.<\/p>\n
