Merkel 防塵圈 PT2型

產品特點

由一個帶有密封刃口和防塵刃口的PTFE異形圈和以及2個

用作預加載元件的O-形圈組成的雙唇口防塵圈。

產品優點

這種雙唇口防塵圈用來提供整體密封性。雙唇口防塵圈PT 2

型主要與我們的活塞桿密封圈OMS-S型結合使用。建議在

密封圈與防塵圈之間設置一個卸壓回油孔。

■■ 在工作過程中，有極好的調節與定位能力

■■ 低摩擦，沒有粘滑現象

■■ 對于行程短和頻率高的使用條件，可以更換材料定做

■■特別適用于大直徑活塞桿

設計要點

請遵守我們的通用設計準則→參照技術手冊

表面加工精度

峰谷高度Ra Rmax

滑動表面* *

溝槽底面≤1.6 um ≤6.3 um

溝槽側面≤3.0 um ≤15.0 um

*作防塵圈使用時，滑動表面的粗糙度應與安裝的密封圈相適應。

安裝和裝配

仔細裝配是保證防塵圈PT2功能正常的先決條件。一般來

說，把防塵圈捏成腎型，就可以快速而簡便地裝配－見技

術手冊。 對于尺寸大于100mm小于150mm，必須使用安

裝工具；小于100mm，安裝溝槽必須是開式。

導入角

倒角的長度和角度，應與活塞桿所用的密封圈相適應
