材料介紹

  • Kintowe DF754雙向運動活塞密封件是一種緊湊型低摩擦密封件,適用于輕載、中載液壓油缸。它包含一個抗磨順性優異的熱塑性彈性體環,該環由一個O形圈預加載。溝槽寬度適用于窄小寬度的活塞,但建議在密封件一側或兩側安裝適當的導向環。Kintowe DFG氟碳導向帶和PFC高強度夾布酚醛導向環的具體尺寸請查閱金泰《聚四氟乙烯材料產品》和《復合材料產品》手冊。

  • DF754-1

產品優勢

低的啟動力和工作摩檫力

優異的耐磨能力

與大多數液壓流體兼容

比普通的PTFE表面環更耐污染

可在較大的表面光潔度范圍內工作

安裝后表面環快速恢復。和普通的PTFE表面環不同,不需要重新定型。

配合使用Kintowe DFG氟碳帶和PFC導向環更為理想
