Merkel導向環(huán) SBK
產品特點
活塞桿用夾織物導向環(huán)。專利設計（專利號：PCT/
EP95/03874）
長行程油缸（活塞桿受力），短導向距離（活塞桿側向偏
移），短行程（潤滑不充分）摩擦力優(yōu)化密封系統，金屬
導向輔助元件，工程機械，重型機械
尺寸表中D1是導向環(huán)的尺寸。同時還標有相應的密封件和
溝槽尺寸。
產品優(yōu)點
SBK型導向環(huán)明顯的優(yōu)于一般的導向帶和導向環(huán)
1.可替代SB和SF型導向環(huán)
2.可以承受巨大的徑向負荷
3.橫向力能夠沿著導向環(huán)的長度，均勻的分布
4.接觸區(qū)里的應力分布，有利于潤滑油從導向環(huán)與接觸面
之間進入
5.避免液壓爬行現象
6.在多導向環(huán)間距較小的情況下，保持良好的性能

在切削深度c＝Rz/2和基準線Cref＝0％時，表面支承長度比Mr >50％至最大90％。
密封件的長期使用效果和可靠性很大程度上由液壓缸的表
面質量決定。因此，表面質量必須清楚的表明。
基于經驗，我們推薦上述的表面質量?？紤]到表面的磨
