標準材料,異形圈:填充聚四氟乙烯F-PTFE或聚氨酯PU,O形圈:丁腈橡膠NBR或氟橡膠FKM
應用范圍:由一個(gè)帶密封刃口和防塵刃口的異行圈以及2個(gè)O形圈組成的PT1防塵圈用于改善整體密封性,具有低摩擦,無(wú)粘滑現象.在工作中有極好的調節和定位能力.可用于農業(yè)機械、液壓機、注塑機、液壓控制系統、叉車(chē)、起重機、滾軋、裝卸機械等設備.
設計時(shí)可參考Trelleborg公司W(wǎng)EMHF系列、Merkel公司PT1系列標準.
特點(diǎn):雙唇口防塵圈用于改善整體密封性,低摩擦，低粘性摩擦,在工作出過(guò)程中有極好的調節和定位能力,對于行程短和頻率高條件下使用的防塵圈可以變換材料定做,可靠性高，在短時(shí)間內能接受滿(mǎn)負荷的工作壓力
