至中密封科技功能用途：SPGW型是双向活塞专用组合密封圈，由PTFE密封环、橡胶弹性环和两个挡圈组成，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。橡胶弹性环提供平稳的补偿磨损径向弹力，使用不同材质的矩形环可以使SPGW型适应非常广泛的工况。SPGW型特别适用于高压工况下活塞的双向密封，改进了SPG型的刮油能力。SPGW型适用于铲车转臂缸、悬臂缸、铲斗缸，推土机起升缸、平铲缸，起重机滑动缸、液压悬架油缸，自卸卡车，压力机，注塑机等。材质：PTFE+NBR+聚酰胺树脂温度：-40℃~+100℃***大压力：50MPa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：SPGW-100*85*12SPGW型双向活塞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DdhDdHCSPGW-5050368.5503694GS0535V2SPGW-6060468.5604694GS0528V2SPGW-63634810.56348115GS3347V2SPGW-65655010.56550115GS3013V2SPGW-70705510.57055115GS0607V2SPGW-75756010.57560115GS0995V2SPGW-80806510.58065115GS0608V2SPGW-85857010.58570115GS0813V2SPGW-90907510.59075115GS0609V2SPGW-95958010.59580115GS0481V4SPGW-10010085121008512.55GS0610V2SPGW-10510590121059012.55GS0973V2SPGW-11011095121109512.55GS0611V2SPGW-1151151001211510012.56.5GS0626V2SPGW-1201201051212010512.56.5GS0612V4SPGW-12512510215.5125102166.5GS0583V2SPGW-13013010715.5130107166.5GS0613V4SPGW-13513511215.5135112166.5GS0908V4SPGW-14014011715.5140117166.5GS0432V4SPGW-15015012715.5150127166.5GS0614V4SPGW-16016013715.5160137166.5GS0615V2SPGW-17017014715.5170147166.5GS0688V2SPGW-18018015715.5180157166.5GS0616V2SPGW-18518516215.5185162166.5GS0653V2SPGW-19019016715.5190167166.5GS0644V2SPGW-20020017715.5200177166.5GS0617V2SPGW-21021018715.5210187166.5GS0654V2SPGW-22022019715.5220197166.5GS0655V2SPGW-22522520215.5225202166.5GS0618V2SPGW-23023020715.5230207166.5GS0664V2SPGW-24024021715.5240217166.5GS0656V2SPGW-2502502221725022217.56.5GS0451V4SPGW-2602602321726023217.57.5GS0605V2SPGW-2702702421727024217.57.5GS0689V2SPGW-2802802521728025217.57.5GS0619V2SPGW-3003002721730027217.57.5GS0510V2SPGW-3203202921732029217.57.5GS0690V2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。)
