Merkel导向环 SBK

产品特点

活塞杆用夹织物导向环。专利设计（专利号：PCT/

EP95/03874）

长行程油缸（活塞杆受力），短导向距离（活塞杆侧向偏

移），短行程（润滑不充分）摩擦力优化密封系统，金属

导向辅助元件，工程机械，重型机械

尺寸表中D1是导向环的尺寸。同时还标有相应的密封件和

沟槽尺寸。

产品优点

 SBK型导向环明显的优于一般的导向带和导向环

1.可替代SB和SF型导向环

2.可以承受巨大的径向负荷

3.横向力能够沿着导向环的长度，均匀的分布

4.接触区里的应力分布，有利于润滑油从导向环与接触面

   之间进入

5.避免液压爬行现象

6.在多导向环间距较小的情况下，保持良好的性能

表面加工精度

峰谷高度Ra Rmax

滑动表面0,05 … 0,3 μm ≤2,5 μm

沟槽底面≤1,6 μm ≤6,3 μm

在切削深度c＝Rz/2和基准线Cref＝0％时，表面支承长度比Mr >50％至最大90％。

密封件的长期使用效果和可靠性很大程度上由液压缸的表

面质量决定。因此，表面质量必须清楚的表明。

基于经验，我们推荐上述的表面质量。考虑到表面的磨

损，密封件的材料也做了相应的改进。－见技术手册
