Juntas simétricas UNR

Descripción

El UNR es una junta en U de perfil simétrico y simple efecto, con el labio de estanqueidad rebajado. Gracias a su geometría reversible puede montarse como junta de vástago o de pistón. Es una solución económica y versátil, de montaje sencillo por encaje, pensada para cilindros de servicio ligero y estándar que trabajan preferentemente a bajas presiones, con un buen cierre estático y dinámico.

Montaje

Montaje en ranura cerrada y mecanizada (se requiere espacio axialmente accesible en diámetros pequeños). Achaflanar y desbarbar los cantos del alojamiento y del vástago o pistón, y limpiar bien el alojamiento antes de instalar. No arrastrar la junta sobre cantos vivos, roscas o chaveteros, usando un casquillo de montaje si es necesario.

VENTAJAS

Perfil simétrico que permite el uso como junta de vástago o de pistón.
Simple efecto, para carga de presión por un solo lado.
Labio de estanqueidad rebajado para un buen cierre a bajas presiones.
Buen comportamiento estático y dinámico.
Montaje sencillo por encaje (snap-on).
Amplio rango de dimensiones y de aplicación.
Buena relación calidad-precio para aplicaciones de exigencia moderada.

MATERIALES

Disponible en distintos compuestos según el fluido y la temperatura de trabajo: NBR, EPDM, FKM, FFKM, NR, CR y VMQ en durezas de 70 a 90 Shore A. PTFE en durezas de 60 Shore D. Ofrece un buen comportamiento frente a aceites hidráulicos según DIN 51524 partes 1 a 3, aceites y grasas lubricantes de base mineral y fluidos hidráulicos ignífugos HFA, HFB y HFC según VDMA 24317. La compatibilidad concreta y los rangos de temperatura dependen del compuesto elegido.

Plano técnico y parámetros de montaje de las juntas simétricas UNR

Este esquema técnico define las cotas y variables geométricas esenciales para la correcta selección y montaje por encaje (snap-on) de la junta simétrica UNR (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), el ancho del perfil de la junta (b), el ancho de la ranura de alojamiento (B) y la longitud del chaflán de entrada (C). El cumplimiento de estas medidas asegura un posicionamiento preciso, facilidades en el montaje y un óptimo comportamiento de estanqueidad estática y dinámica en aplicaciones de exigencia moderada.

Vista tridimensional y componentes de las juntas simétricas UNR

Esta ilustración en 3D le detalla la estructura fundamental de la junta simétrica UNR. Podrá observar claramente sus elementos clave: sus labios de estanqueidad simétricos y la base del perfil en U. Su diseño compacto de geometría reversible permite utilizarla indistintamente como junta de vástago o de pistón, ofreciendo un sellado eficaz y un montaje sencillo por encaje (snap-on).
