A42 型防尘圈
标准材料：聚氨酯 AU92
应用范围：液压、气动往复运动环境。
说明：
A42型防尘圈被安装在液压缸内作轴向运动的活塞杆和柱塞上。当活塞杆或柱塞运动时，灰尘能进入液压缸内，从而引起密封圈、导向环和支承圈损伤和过早的磨损。A42型防尘圈能有效防止灰尘进入液压缸。
作用：
A42型防尘圈是一种单向作用的防尘圈。当活塞杆向里运动时压在活塞杆上的防尘圈的唇口将杆表面的脏污刮去，对密封件和密封配件及介质起保护作用。A42型防尘圈利用了径向的压力来除去颗粒、灰尘和水。沟槽外部的压力能形成静密封。聚氨酯材料的高耐磨性使A42型防尘圈的使用寿命很长。
优点：-良好的刮尘作用-设计紧凑-沟槽设计简单-安装和拆卸简便-价格便宜-轻微的旋转和摆动不影响工作性能
安装：A42型防尘圈安装于半闭合的沟槽中。
介质：矿物油、油脂和难燃液等。
使用条件：温度：-40℃～+100℃ 运动速度：≤2 m / s
