標準材料,密封體:填充聚四氟乙烯F-PTFE,彈性體:丁腈橡膠NBR,L環(huán):聚甲醛POM或尼龍PA
應用范圍,GGDI由一個(gè)密封環(huán)、兩個(gè)L型POM（直徑Ф400 mm以上用PA）支撐環(huán)和一個(gè)施力的O形圈組成活塞組合密封.支撐環(huán)起支撐和引導作用,以確保緊密的密封環(huán)境.滑環(huán)依靠O圈的施力緊壓活塞,提供密封作用.可在礦物油,水基潤滑液、改性水基潤滑液和其他液體中使用. 設計選用時(shí)可參考Hunger公司GGDA系列標準.特點(diǎn),安裝簡(jiǎn)易,高耐磨,低摩擦，無(wú)粘滑現象.
