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.
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.

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).
