標(biāo)準(zhǔn)材料:密封體:丁腈橡膠NBR或氟橡膠FKM,擋圈:聚酯彈性,耐磨環(huán):聚甲醛POM或尼龍PA
應(yīng)用范圍,KGB組合密封經(jīng)常在作往復(fù)運(yùn)動的液壓缸和活塞中用作密封元件,如:推土機(jī)、起重機(jī)、叉車、液壓閘門及農(nóng)業(yè)機(jī)械等.安裝在包括ISO6547標(biāo)準(zhǔn)溝槽的閉合溝槽中.設(shè)計選用時可參考Trelleborg公司PCA、PCB系列、Parker公司ZX系列、AS公司KGD系列標(biāo)準(zhǔn). 特點:可安裝在封閉式溝槽中,能降低加工成本,活塞總長度較短,活塞的生產(chǎn)成本低,密封圈和耐磨環(huán)價廉,對間隙的抗擠出能力極強(qiáng),彈性密封圈不會扭曲和翻轉(zhuǎn),良好的防泄漏性能,開切口的擋圈和導(dǎo)向環(huán)安裝方便.
