至中密封科技功能用途：STD型是活塞专用组合密封圈，具有双向密封作用，结构紧凑，摩擦系数低，主要用于中低压液压缸。STD型由一个提供弹力的O型圈和PTFE密封环组成，可直接安装在整体式沟槽中，当压力升高时，流体进入沟槽使O型圈产生形变压缩PTFE密封环，从而增加密封效果。由于只有PTFE密封环与油缸内壁接触，摩擦力非常低，这样就会有效地消除爬行现象。STD型适合沟槽宽度较小的活塞，但必须在密封圈两侧设置两道导向环。STD型的密封环是PTFE材质，具有优良的耐温、耐酸碱特性，这样就可以配合不同材质的O型圈使用，从而适合广泛的工作环境。但此密封圈不建议使用于固***置并且需要保压的油缸。材质：PTFE+NBR/FKM温度：-45℃~+200℃压力：35MPa介质：石油基液压油、乳化液、水乙二醇液压油、油水乳化型液压油等。执行标准：GB/T15242.1-94订货标示方法：STD-100*84.5*6.3STD型活塞密封圈型号沟槽尺寸表型号沟槽尺寸DdLRmaxE配套O型圈STD-16165.83.20.50.85～0.58.5*2.65STD-181810.53.20.50.85～0.510.5*2.65STD-202012.53.20.50.85～0.512.5*2.65STD-222214.53.20.50.85～0.514*2.65STD-252517.53.20.50.85～0.517*2.65STD-282820.53.20.50.85～0.520*2.65STD-303022.53.20.50.85～0.521.2*2.65STD-323224.53.20.50.85～0.523.6*2.65STD-353527.53.20.50.85～0.526.5*2.65STD-4040294.20.70.85～0.528*3.55STD-4545344.20.70.85～0.533.5*3.55STD-5050394.20.70.85～0.538.7*3.55STD-5555444.20.70.85～0.543.7*3.55STD-6060494.20.70.85～0.547.5*3.55STD-6363524.20.70.85～0.550*3.55STD-6565544.20.70.85～0.553*3.55STD-7070594.20.70.85～0.558*3.55STD-7575644.20.70.85～0.563*3.55STD-808064.56.31.21～0.663*5.3STD-858569.56.31.21～0.669*5.3STD-909074.56.31.21～0.673*5.3STD-10010084.56.31.21～0.682.5*5.3STD-11011094.56.31.21～0.692.5*5.3STD-120120104.56.31.21～0.6103*5.3STD-125125109.56.31.21～0.6109*5.3STD-130130114.56.31.21～0.6112*5.3STD-140*6.3140124.56.31.21～0.6122*5.3STD-140*8.11401198.11.51.25～0.6118*7STD-1501501298.11.51.25～0.6128*7STD-1601601398.11.51.25～0.6136*7STD-1701701498.11.51.25～0.6145*7STD-1801801598.11.51.25～0.6155*7STD-1901901698.11.51.25～0.6165*7STD-2002001798.11.51.25～0.6175*7STD-2102101898.11.51.25～0.6185*7STD-222201998.11.51.25～0.6195*7STD-2302302098.11.51.25～0.6200*7STD-2402402198.11.51.25～0.6212*7STD-2502502298.11.51.25～0.6224*7STD-2602602398.11.51.25～0.6236*7STD-2802802598.11.51.25～0.6256*7STD-2902902698.11.51.25～0.6265*7STD-3003002798.11.51.25～0.6272*7STD-3103102898.11.51.25～0.6280*7STD-3203202998.11.51.25～0.6290*7STD-330330305.58.11.51.25～0.6300*7STD-340340315.58.11.51.25～0.6307*7STD-350350325.58.11.51.25～0.6316*7STD-360360335.58.11.51.25～0.6330*7STD-370370345.58.11.51.25～0.6335*7STD-380380355.58.11.51.25～0.6345*7STD-390390365.58.11.51.25～0.6355*7STD-400400375.58.11.51.25～0.6365*7STD-420420395.58.11.51.25～0.6387*7STD-440440415.58.11.51.25～0.6400*7STD-450450425.58.11.51.25～0.6412*7STD-460460435.58.11.51.25～0.6425*7STD-480480455.58.11.51.25～0.6450*7STD-500500475.58.11.51.25～0.6462*7STD-520520495.58.11.51.25～0.6487*7STD-540540515.58.11.51.25～0.6500*7STD-550550525.58.11.51.25～0.6515*7STD-560560535.58.11.51.25～0.6530*7STD-580580555.58.11.51.25～0.6545*7STD-600600575.58.11.51.25～0.6560*7STD-620620595.58.11.51.25～0.6580*7STD-640640615.58.11.51.25～0.6600*7STD-650650625.58.11.51.25～0.6615*7STD-660660635.58.11.51.25～0.6630*7STD-680680655.58.11.51.25～0.6650*7更多产品型号尺寸请联系我们；我们一直坚持提供“高质量的产品、合理的价格和优质的服务”的经营理念，请不要犹豫和我们联系，我们将非常乐意的为您提供高质量的产品和优质的服务！成达斯密封公司正致力于不断完善库存和开发新的产品。从而解决了进口产品周期长、价格高等问题。如果您有其他特殊密封件方面的需求，请直接与我公司联系，我公司将为您提供任何一种特殊规格的订货服务。)
