MBA型杆封

一、性能与用途

    MBA型轴封，是唇形密封进一步发展的结果。它兼有了高弹性O形圈和唇形密封材料耐磨性的优点。这种密封件因其特殊的装置（油槽里加放了O形圈）而主要用于行走设备。这个O形圈保证了密封唇口在低压或真空条件下的预压缩量，这对密封性能是很必要的。密封力基本上与温度的变化无关，并且即使发生某种程度的磨损也会保证必要的预压缩量。唇口由于系统压力的增加而通过受压变形的O形圈传递唇口上，从而使唇口紧紧抱住活塞杆起到优良的密封效果。主要用于柱塞、活塞杆、伸缩缸、气钻、锻压机以及行走等液压设备的密封。

二、材质

    进口聚氨脂PU＋腈胶NBR。

三、工况条件

    工作压力：≤350bar；
    工作温度：-35+80℃，峰值高达+95℃；
    表面速度：≤0.5m/s。

四、安装

    密封件有一个轴向间隙。为了避免在安装期间损坏密封唇口，不要将密封件在锐边上拉动。通常，这类密封件是装入闭式沟槽中的，对于个别极限直径和极限横断面的情况，且结构不允许采用开放式沟槽时，这类密封件在安装前应对其进行加温软化或使用安装辅助工具。

五、主要优点

    特别强的耐磨性；
    对震动载荷和压力峰值的不敏感性；
    很高的抗挤压性；
    在无载和低温的条件下具有理想的密封作用；
    适用于苛刻的工作条件；
    易于安装。

六、设计标准

    本系列符合Parker公司BA系列。

七、标注及订货方法

    MBA型活塞杆密封用订货号来标注，示例：MBA-1826 PU+NBR
