功能用途：USH型具有较窄的截面，是内外唇口等高的对称型U型密封圈。可以很容易地装入整体式构成中。由于截面较为窄小，USH型一般使用在压力较小的液压油缸中。选用***橡胶或者氟橡胶可以适应不同工况下使用。为防止挤出，建议在压力大于14MPa以上的工况下使用时在密封件的根部添加挡圈。材质：NBR橡胶/FKM氟橡胶温度：NBR橡胶：-30℃~100℃FKM氟橡胶：-20℃~200℃***大压力：20MPa介质：NBR：通用石油基液压油、水乙二醇液压油、油-水乳化型液压油。FKM：通用石油基液压油、***液压油等。执行标准：日本NOK订货标示方法：USH-60*70*6R≤0.3R1≤0.5活塞杆表面应作0.8μmRmax(0.2~0.4μmRa)的抛光R≤0.3油缸内表面应作0.4~3.2μmRmax(0.1~0.8μmRa)的研磨或抛光型号密封圈公称尺寸沟槽尺寸dDHdDHaHb挡圈厚度USH-661256125.77.21.5USH-11.211.219.2511.219.25.77.21.5USH-12.512.520.5512.520.55.77.21.5USH-141422514225.77.21.5USH-161624516245.77.21.5USH-181826518265.77.21.5USH-202028520285.77.21.5USH-22.422.430522.4305.77.21.5USH-23.523.531.5523.531.55.77.21.5USH-252533525335.77.21.5USH-282835.552835.55.77.21.5USH-30304063040792USH-31.531.541.5631.541.5792USH-32324263242792USH-35354563545792USH-35.535.545635.545792USH-38384863848792USH-40405064050792USH-45A455564555792USH-454556745568102USH-50506065060792USH-505060750608102USH-53536365363792USH-55556565565792USH-56566665666792USH-58586865868792USH-60A607066070792USH-606071760718102USH-63637366373792USH-65657566575792USH-67677766777792USH-70708067080792USH-71718067180792USH-75758567585792USH-80809068090792USH-858510098510010133USH-909010599010510133USH-959511099511010133USH-989811299811210133USH-100100115910011510133USH-110110125911012510133USH-112112125911212510133USH-115115130911513010133USH-120120135912013510133USH-125125140912514010133USH-136136150913615010133USH-140140155914015510133USH-145145160914516010133USH-150150165915016510133USH-160160175916017510133USH-165165180916518010133USH-1801802001218020013163USH-2002002201220022013163由于篇幅有限更多产品型号尺寸请联系我们；公司宗旨：不竞争价格，定竞争质量。联系方式；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。热诚欢迎新老客户光临惠热诚欢迎新老客户光临惠)
