Juntas simétricas UNP

Descripción

El UNP es una junta en U de perfil simétrico y simple efecto, apta tanto para vástago como para pistón gracias a su geometría reversible. Sus dos labios de estanqueidad con canto ligeramente rebajado garantizan un buen cierre estático y dinámico bajo carga de presión por un solo lado. Es una solución robusta, de montaje sencillo por encaje y amplio rango de aplicación, pensada para cilindros hidráulicos de exigencia moderada en la industria general y la hidráulica móvil.

Montaje

Montaje en ranura cerrada y mecanizada. 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. Lubricar el vástago o pistón antes del montaje, calentar la junta en aceite a 80 °C facilita su colocación.

VENTAJAS

Perfil simétrico que permite el uso como junta de vástago o de pistón.
Simple efecto, para carga de presión por un solo lado.
Buen cierre estático y dinámico.
Diseño robusto de larga vida útil.
Montaje sencillo por encaje (snap-on).
Amplio rango de dimensiones y de aplicación.
Buena relación calidad-precio para aplicaciones de exigencia moderada.

MATERIALES

Fabricado en poliuretano (PU) con durezas de 92 a 95 Shore A, un material de gran resistencia mecánica y a la abrasión que ofrece un excelente comportamiento frente a aceites hidráulicos según DIN 51524, aceites y grasas lubricantes de base mineral y fluidos hidráulicos ignífugos HFA, HFB y HFC.

Plano técnico y parámetros de montaje de las juntas simétricas UNP

Este esquema técnico define las cotas y variables geométricas esenciales para la correcta selección y montaje por encaje (snap-on) de la junta simétrica UNP (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 estos valores asegura un adecuado guiado y posicionamiento, garantizando un excelente cierre estático y dinámico en cilindros hidráulicos de exigencia moderada.

Vista tridimensional y componentes de las juntas simétricas UNP

Esta ilustración en 3D le detalla la estructura fundamental de la junta simétrica UNP. Podrá observar claramente sus elementos clave: el cuerpo de poliuretano (PU), sus labios de estanqueidad simétricos y el canto de estanqueidad de perfil ligeramente rebajado. Su diseño robusto de geometría reversible le permite funcionar indistintamente en vástago o pistón, ofreciendo un excelente cierre estático y dinámico y un montaje sencillo por encaje (snap-on).
