Juntas simétricas CNR

Descripción

El CNR es una junta simétrica de simple efecto, fabricada con tejido y caucho de gran resistencia al desgaste, indicada para el sellado de cilindros hidráulicos de servicio ligero y medio. Su perfil simétrico permite emplearla tanto en pistón como en vástago, e incluso en cilindros de doble efecto. Gracias a su diseño robusto, ofrece un buen sellado aun cuando los vástagos y los aros guía están desgastados.

Montaje

Las juntas simétricas de tejido se montan en pistones partidos o ranuras abiertas con anillo de retención. Achaflanar y eliminar los cantos vivos del alojamiento para no dañar la junta, y limpiar bien el alojamiento antes del montaje. Para la guía del pistón o del vástago se recomienda utilizar aros o cintas de guiado.

VENTAJAS

Excelente estanqueidad a presiones bajas y medias.
Perfil simétrico apto para pistón y vástago, y para cilindros de doble efecto.
Construcción de tejido y caucho de gran resistencia al desgaste.
Buen funcionamiento incluso con vástagos y aros guía desgastados.
Diseño robusto y larga vida útil.
Amplia gama de medidas métricas y en pulgadas.

MATERIALES

Disponible en distintos compuestos según el fluido y la temperatura de trabajo: NBR, EPDM, FKM, FFKM, NR, CR y VMQ en durezas de entre 70 y 90 Shore A, y PTFE en dureza de 60 Shore D, todos ellos con refuerzo de tejido que aporta resistencia a la extrusión. Ofrece un buen comportamiento frente a aceites minerales y biodegradables, fluidos hidrosolubles y de agua-glicol, y aceites y grasas lubricantes de base mineral.

Plano técnico y parámetros de montaje de las juntas simétricas CNR

Este esquema técnico define las cotas y variables geométricas esenciales para la correcta selección y el montaje por encaje (snap-on) de la junta simétrica CNR, de perfil compacto en una sola pieza y geometría reversible, apta tanto para vástago como para pistón. En él encontrará las dimensiones críticas vinculadas a las tablas de especificaciones, tales como el diámetro interior (Ød), el diámetro exterior (ØD) y el ancho del perfil de la junta (b), junto con el ancho de la ranura de alojamiento (B), su profundidad (E), el radio de acuerdo del fondo de ranura (rs 0,40) y el ángulo de entrada de 20°. El cumplimiento de estas medidas asegura un posicionamiento preciso, un montaje sin deformación del perfil y un óptimo comportamiento de estanqueidad estática y dinámica en aplicaciones de doble efecto con presiones medias y altas.

Vista tridimensional y componentes de las juntas simétricas CNR

Esta ilustración en 3D le detalla la estructura fundamental de la junta simétrica CNR. Podrá observar claramente su elemento característico: un cuerpo de elastómero de una sola pieza con labios de estanqueidad simétricos, cuya interferencia radial garantiza el contacto sobre la superficie de deslizamiento incluso a baja presión. Su diseño compacto de geometría reversible permite utilizarla indistintamente como junta de vástago o de pistón, ofreciendo un sellado eficaz, una buena capacidad de adaptación a las tolerancias del alojamiento y un montaje sencillo por encaje (snap-on).
