Tecnolog\u00eda de rodamientos de bolas de contacto angular de doble hilera<\/h2>\n

A rodamiento de bolas de contacto angular de doble hilera<\/strong><\/a> utiliza un dise\u00f1o con dos filas de bolas de acero dispuestas sim\u00e9tricamente, que puede soportar simult\u00e1neamente fuerzas radiales y axiales. Su estructura \u00fanica le confiere una mayor rigidez y capacidad de carga, y es especialmente adecuado para escenarios industriales con estrictos requisitos de precisi\u00f3n de funcionamiento y rendimiento de soporte de carga. En comparaci\u00f3n con los modelos de una hilera, el dise\u00f1o de doble hilera mejora significativamente el rendimiento general del rodamiento, especialmente en condiciones de funcionamiento a alta velocidad.<\/p>\n

\"Double<\/p>\n

Principales ventajas de rendimiento<\/h2>\n

Capacidad de carga compuesta<\/h3>\n

El efecto sin\u00e9rgico de las bolas de acero de doble hilera puede hacer frente simult\u00e1neamente a las tensiones radiales y axiales compuestas, y la capacidad de carga aumenta en m\u00e1s de 40% en comparaci\u00f3n con los rodamientos de una hilera.<\/p>\n

Caracter\u00edsticas de funcionamiento de precisi\u00f3n<\/h3>\n

El dise\u00f1o optimizado del \u00e1ngulo de contacto garantiza un funcionamiento de baja fricci\u00f3n y un excelente control del aumento de temperatura, cumpliendo los requisitos de tolerancia a nivel de micras de los equipos de precisi\u00f3n.<\/p>\n

Dise\u00f1o duradero<\/h3>\n

La distribuci\u00f3n uniforme de la carga reduce el desgaste local y, gracias al acero de alta calidad y a los procesos de tratamiento t\u00e9rmico, la vida \u00fatil se prolonga en 30%-50%.<\/p>\n

Adaptabilidad vers\u00e1til<\/h3>\n

Los tama\u00f1os normalizados cubren una amplia gama de condiciones de trabajo y admiten soluciones de estanquidad personalizadas (estanquidad con o sin contacto).<\/p>\n

Principales \u00e1mbitos de aplicaci\u00f3n<\/h2>\n

Fabricaci\u00f3n de equipos de gama alta<\/h3>\n

El husillo de la m\u00e1quina herramienta de enlace de cinco ejes adopta rodamientos de precisi\u00f3n de nivel P4 para garantizar una precisi\u00f3n de mecanizado de 0,001 mm.<\/p>\n

\"Double<\/p>\n

Veh\u00edculos de nueva energ\u00eda<\/h3>\n

Los rodamientos del motor de accionamiento deben alcanzar una velocidad superior a 20.000 rpm y soportar la fuerza electromagn\u00e9tica axial del motor.<\/p>\n
