Vis\u00e3o geral dos rolamentos axiais de esferas de contacto angular<\/strong><\/h2>\n

Rolamento axial de esferas de contacto angular<\/strong><\/a> \u00e9 um rolamento especialmente concebido que pode suportar for\u00e7a axial e um certo grau de for\u00e7a radial ao mesmo tempo. A sua estrutura utiliza esferas de a\u00e7o como elementos rolantes e atinge uma elevada rigidez e um forte desempenho de carga com a ajuda de \u00e2ngulos de contacto espec\u00edficos dos an\u00e9is interior e exterior. O valor do \u00e2ngulo de contacto determina diretamente o limite de carga e a adaptabilidade da velocidade do rolamento. Os \u00e2ngulos t\u00edpicos incluem 15\u00b0, 25\u00b0 e 40\u00b0.<\/p>\n

Diretrizes de sele\u00e7\u00e3o
\nAplica\u00e7\u00f5es de alta velocidade (por exemplo, fusos de m\u00e1quinas-ferramentas): Optar por \u00e2ngulos de contacto mais pequenos (por exemplo, 45\u00b0) e dar prioridade aos limites de velocidade.<\/p>\n

Cargas axiais elevadas (por exemplo, turbinas e\u00f3licas): Escolha \u00e2ngulos de contacto maiores (por exemplo, 60\u00b0) e verifique as classifica\u00e7\u00f5es de carga din\u00e2mica.<\/p>\n

Ambientes agressivos (alta temperatura\/corros\u00e3o): Considerar rolamentos h\u00edbridos de a\u00e7o inoxid\u00e1vel ou cer\u00e2mica.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
