Merkel 防尘圈 PT2型

产品特点

由一个带有密封刃口和防尘刃口的PTFE异形圈和以及2个

用作预加载元件的O-形圈组成的双唇口防尘圈。

产品优点

这种双唇口防尘圈用来提供整体密封性。双唇口防尘圈PT 2

型主要与我们的活塞杆密封圈OMS-S型结合使用。建议在

密封圈与防尘圈之间设置一个卸压回油孔。

■■ 在工作过程中，有极好的调节与定位能力

■■ 低摩擦，没有粘滑现象

■■ 对于行程短和频率高的使用条件，可以更换材料定做

■■特别适用于大直径活塞杆

设计要点

请遵守我们的通用设计准则→参照技术手册

表面加工精度

峰谷高度Ra Rmax

滑动表面* *

沟槽底面≤1.6 um ≤6.3 um

沟槽侧面≤3.0 um ≤15.0 um

*作防尘圈使用时，滑动表面的粗糙度应与安装的密封圈相适应。

安装和装配

仔细装配是保证防尘圈PT2功能正常的先决条件。一般来

说，把防尘圈捏成肾型，就可以快速而简便地装配－见技

术手册。 对于尺寸大于100mm小于150mm，必须使用安

装工具；小于100mm，安装沟槽必须是开式。

导入角

倒角的长度和角度，应与活塞杆所用的密封圈相适应
