Merkel 防塵圈 PT2型
產(chǎn)品特點(diǎn)
由一個(gè)帶有密封刃口和防塵刃口的PTFE異形圈和以及2個(gè)
用作預(yù)加載元件的O-形圈組成的雙唇口防塵圈。
產(chǎn)品優(yōu)點(diǎn)
這種雙唇口防塵圈用來(lái)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(jié)合使用。建議在
密封圈與防塵圈之間設(shè)置一個(gè)卸壓回油孔。
■■ 在工作過(guò)程中,有極好的調(diào)節(jié)與定位能力
■■ 低摩擦,沒(méi)有粘滑現(xiàn)象
■■ 對(duì)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

安裝和裝配
仔細(xì)裝配是保證防塵圈PT2功能正常的先決條件。一般來(lái)
說(shuō),把防塵圈捏成腎型,就可以快速而簡(jiǎn)便地裝配-見(jiàn)技
術(shù)手冊(cè)。 對(duì)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(kāi)式。
