一、性能與用途
&sp;&sp;&sp;&sp;由一個(gè)低磨擦的填充聚四氟乙烯（PTFE）環(huán)和O形橡膠密封圈組合而成，O形圈提供的密封預(yù)緊力，并對PTFE環(huán)的磨耗起補(bǔ)償作用。PTFE摩擦系數(shù)小，動(dòng)靜摩擦系數(shù)相近。適用于高低速往復(fù)運(yùn)動(dòng)及高壓系統(tǒng)的油缸活塞桿密封。采用兩個(gè)階梯圈密封，可泄露。一般要和導(dǎo)向環(huán)配套使用。軸徑小于Φ30的規(guī)格，應(yīng)采用分體式溝槽。
二、材 質(zhì)
&sp;&sp;&sp;&sp;階梯圈為填充聚四氟乙烯PTFE，O形圈為橡膠R或氟膠FKM。
三、工況條件
&sp;&sp;&sp;&sp;耐 壓：0-40MPa；
&sp;&sp;&sp;&sp;往復(fù)速度：≤5m/s；
&sp;&sp;&sp;&sp;工作溫度：丁晴R：-30～+120℃，氟膠FKM：-20～+200℃；
&sp;&sp;&sp;&sp;工作介質(zhì)：液壓油、氣、水（在磷酸酯液壓油中選用氟膠)。
四、設(shè)計(jì)標(biāo)準(zhǔn)
&sp;&sp;&sp;&sp;本系列合GB/T 15242.1-94及GB/T 15242.3-94標(biāo)準(zhǔn)?？蓞⒖?span lang="EN-US">Parker公司OD系列、Merkel公司-OMS-MR及霞板公司S55013系列。
五、標(biāo)注方法
&sp;&sp;&sp;&sp;軸用階梯圈用訂貨號來標(biāo)注，示例：GSJ-1000 PTFE+R
六、結(jié)構(gòu)裝置
