功能用途：SPG型是活塞专用组合密封圈，由PTFE密封环和矩形橡胶环组成，用于液压油缸的活塞双向密封。PTFE密封环具有摩擦系数低、耐磨损、抗挤压、耐高温、耐腐蚀等优良特性。矩形环提供比O型圈更加平稳的补偿磨损径向弹力，使用不同材质的矩形环可以使SPG型适应非常广泛的工况。SPG是一种大范围适应的组合密封，特别适合于控制油缸、伺服系统、机床、快速响应油缸及建筑机械中的双向活塞油缸。材质：PTFE+NBR温度：-40℃~+100℃压力：35MPa介质：通用石油基液压油、谁乙二醇抗燃液压油、油-水乳化型液压油。执行标准：日本NOK订货标示方法：SPG-20.5*30*4.SPG型活塞专用组合密封圈型号沟槽尺寸表型号密封件公称尺寸沟槽尺寸NOK零件号dDhdDHCSGP-3020.5304.320.5304.52GS0327V0SGP-31.52231.54.32231.54.53.5GS0328V0SGP-3222.5324.322.5324.53.5GS0329V0SGP-3525.5354.325.5354.53.5GS0330V0SGP-35.52635.54.32635.54.53.5GS0331V0SGP-4030404.330404.53.5GS0332V0SGP-4535454.335454.53.5GS0333V0SGP-5040504.340504.54GS0334V0SGP-5545554.345554.54GS0335V0SGP-5646564.346564.54GS0336V0SGP-6050604.350604.54GS0337V0SGP-6348637.348637.54GS0338V0SGP-6550657.350657.54GS0339V0SGP-6954697.354697.54GS0340V0SGP-7055707.355707.55GS0341V0SGP-7156717.356717.55GS0342V0SGP-7560757.360757.55GS0343V0SGP-8065807.365807.55GS0344V0SGP-8570857.370857.55GS0345V0SGP-9075907.375907.55GS0310V0SGP-9580957.380957.55GS0346V0SGP-100851007.3851007.55GS0347V0SGP-108921087.3921087.55GS0348V0SGP-110941107.3941107.55GS0311V0SGP-112961127.3961127.56.5GS0349V0SGP-1201041207.31041207.56.5GS0350V0SGP-1251091257.31091257.56.5GS0351V0SGP-1301141307.31141307.56.5GS0352V0SGP-1401241407.31241407.56.5GS0353V0SGP-1451291457.31291457.56.5GS0885V0SGP-1501341507.31341507.56.5GS0354V0SGP-1551391557.31391557.56.5GS3133V1SGP-1601441607.31441607.56.5GS0355V0SGP-17014817010.8148170116.5GS0356V0SGP-18015818010.8158180116.5GS0357V0SGP-19016819010.8168190116.5GS0358V0SGP-20017820010.8178200116.5GS0359V0SGP-20418220410.8182204116.5GS0360V0SGP-21018821010.8188210116.5GS0361V0SGP-22019822010.8198220116.5GS0842V0SGP-22420222410.8202224116.5GS0362V0SGP-22520322510.8203225116.5GS0363V0SGP-23020823010.8208230116.5GS0364V0SGP-24021824010.8218240116.5GS0365V0SGP-25022825010.8228250116.5GS0366V0SGP-26023626011.7236260127.5GS0700V0SGP-27024627011.7246270127.5GS0701V0SGP-28025628011.7256280127.5GS0702V0SGP-29026629011.7266290127.5GS0703V0SGP-30027630011.7276300127.5GS0704V0SGP-31028631011.7286310127.5GS0705V0SGP-32029632011.7296320127.5GS0706V0SGP-3303083309.753083301010GS0408V0SGP-36033636011.73363601210GS0917V0SGP-48545548514.84554851510GS0504V1SGP-50047050014.84705001510GS0261V2SGP-55051555017.251555017.510GS0379V2SGP-60057060014.85706001510GS0324V2SGP-65062065014.86206501515GS0527V0SGP-72069072014.86907201515GS0492V0SGP-80078580012.77858001315GS0520V0SGP-90087090024.58709002515GS0407V2SGP-930890930198909302015GS0466V1SGP-93592093512.79209351315GS0521V0SGP-95092595017.79259501815GS0285V2SGP-1000960100019.796010002020GS0512V0SGP-10601020106019.7102010602020GS0587V0SGP-11201080112019.7108011202020GS0584V0SGP-11501110115019.7111011502020GS3007V0SGP-11801130118019.7113011802020GS0599V1SGP-12101170121019117012102020GS0465V0SGP-12501210125019.7121012502020GS0281V0SGP-12601220126019.7122012602020GS0851V0SGP-14001350140019.7135014002020GS0402V0SGP-15001460150019.7146015002020GS0852V0SGP-16501600165024160016502520GS0579V0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。)
