所属技术：密封技术

## 系列介绍

KA型旋转密封的设计,由纤维增强的橡胶密封部分和两个挡圈组成,挡圈增加了稳定性并免于挤出,更适合有一定偏心率的应用。得益于其设计,动态表面可以存储润滑油,保持密封面有一定的油膜,减少干摩擦。 • 在低压或者无压力的情况下提高密封性能。 • 坚固的密封结构使其适应严苛的工况条件。 • 优异的耐磨性。 • 对峰值压力不敏感。 • 选择合适的材料可以耐很高的温度。 • 耐挤出。 • 可安装在封闭或开放式沟槽。 应用范围 它主要适用于系统压力从密封件一侧到另外一侧交替的应用,如旋转履带的心轴,回转接头,软管卷绕轮以及液压机床。 派克KA系列旋转组合密封有以下材料可选: Q5024
