詳細介紹

MBA型桿封

一、性能與用途

    MBA型軸封，是唇形密封進一步發展的結果。它兼有了高彈性O形圈和唇形密封材料耐磨性的優點。這種密封件因其特殊的裝置（油槽里加放了O形圈）而主要用于行走設備。這個O形圈保證了密封唇口在低壓或真空條件下的預壓縮量，這對密封性能是很必要的。密封力基本上與溫度的變化無關，并且即使發生某種程度的磨損也會保證必要的預壓縮量。唇口由于系統壓力的增加而通過受壓變形的O形圈傳遞至唇口上，從而使唇口緊緊抱住活塞桿起到優良的密封效果。主要用于柱塞、活塞桿、伸縮缸、氣鉆、鍛壓機以及行走等液壓設備的密封。

二、材質

    進口聚氨脂PU＋丁腈膠NBR。

三、工況條件

    工作壓力：≤350bar；
    工作溫度：-35至+80℃，峰值高達+95℃；
    表面速度：≤0.5m/s。

四、安裝

    密封件有一個軸向間隙。為了避免在安裝期間損壞密封唇口，不要將密封件在銳邊上拉動。通常，這類密封件是裝入閉式溝槽中的，對于個別極限直徑和極限橫斷面的情況，且結構不允許采用開放式溝槽時，這類密封件在安裝前應對其進行加溫軟化或使用安裝輔助工具。

五、主要優點

    特別強的耐磨性；
    對震動載荷和壓力峰值的不敏感性；
    很高的抗擠壓性；
    在無載和低溫的條件下具有理想的密封作用；
    適用于最苛刻的工作條件；
    易于安裝。

六、設計標準

    本系列符合Parker公司BA系列。

七、標注及訂貨方法

    MBA型活塞桿密封用訂貨號來標注，示例：MBA-1826 PU+NBR
