PARKER派克OR型双作用旋转密封旋转传动装置的生产厂家都比较喜欢采用简单的密封结构。这可以用内径密封的OR型密封件来实现。它们由耐磨的低摩擦滑动环和丁晴橡胶O形圈组成。OR形旋转密封件主要用于压力从密封件的一侧交替至另一侧的地方，如旋转履带心轴、回转接头、软管卷挠轮，以及用于机床液压。若此密封件用于端部密封，***好用防尘圈来闭合此结构。考虑到特殊的工作条件，OR型旋转密封件开有一条或二条环形润滑槽。这种密封结构的优点：●安装长度短。●起动摩擦小，无爬行现象，即使在低速情况下也能保证平稳的运动。●低磨损。●抗挤出。●耐高温。●由于活塞杆密封圈有广泛的化学兼容性，以及各种各样可供选用的O形圈材料，故几乎可与所有介质相容。●可提供***大直径2500mm的产品。应用范围：工作压力：≤300bar工作温度：-30至+100°C*表面速度：≤1.0m/s对于旋转运动，推荐在p•V≤40范围内使用。*超出标准温度的工作情况，请与派克公司咨询合适的O形圈材料。请将此密封与导向带一起共同使用（F3：闭式，Z型）。安装：小于30mm杆径需开式沟槽。标准材料：滑动环：Polon®033,改性的PTFE+25%碳。O形圈：N0674，邵氏硬度约为70的NBR橡胶。若有特殊要求（压力、温度、速度等），请与本公司的咨询服务部联系，他们会向您推荐合适的材料和结构。OR型双作用PTFE旋转密封圈产品号d*D*LOR004003300161A4*8.9*2.2OR005003300161A5*9.9*2.2OR007003300161A7*11.9*2.2OR008003300161B8*15.5*3.2OR010003300161B10*17.5*3.2OR012003300161B12*19.5*3.2OR014003300161B14*21.5*3.2OR015003300161B15*22.5*3.2OR016003300161B16*23.5*3.2OR018003300161B18*25.5*3.2OR020003300161C20*31.0*4.2OR022003300161C22*33.0*4.2OR024003300161C24*35.0*4.2OR025003300161C25*36.0*4.2OR026003300161C26*37.0*4.2OR028003300161C28*39.0*4.2OR030003300161C30*41.0*4.2OR032003300161C32*43.0*4.2OR035003300161C35*46.0*4.2OR037003300161C37*48.0*4.2OR038003300161D38*53.5*6.3OR040003300161D40*55.5*6.3OR042003300161D42*57.5*6.3OR045003300161D45*60.5*6.3OR048003300161D48*63.5*6.3OR050003300161D50*65.5*6.3OR052003300161D52*67.5*6.3OR055003300161D55*70.5*6.3OR058003300161D58*73.5*6.3OR060003300161D60*75.5*6.3OR065003300161D65*80.5*6.3OR070003300161D70*85.5*6.3OR075003300161D75*90.5*6.3OR080003300161D80*95.5*6.3OR085003300161D85*100.5*6.3OR090003300161D90*105.5*6.3OR095003300161D95*110.5*6.3OR100003300161D100*115.5*6.3OR110003300161D110*125.5*6.3OR120003300161D120*135.5*6.3OR125003300161D125*140.5*6.3OR130003300161D130*145.5*6.3OR140003300161D140*155.5*6.3OR150003300161D150*165.5*6.3OR155003300161D155*170.5*6.3OR160003300161D160*175.5*6.3OR170003300161D170*185.5*6.3OR175003300161D175*190.5*6.3OR180003300161D180*195.5*6.3OR185003300161D185*200.5*6.3OR190003300161D190*205.5*6.3OR195003300161D195*210.5*6.3OR200003300161E200*221.0*8.1OR210003300161E210*231.0*8.1OR220003300161E220*241.0*8.1OR225003300161E225*246.0*8.1OR230003300161E230*251.0*8.1OR240003300161E240*261.0*8.1OR250003300161E250*271.0*8.1OR260003300161F260*284.5*8.1OR270003300161F270*294.5*8.1OR280003300161F280*304.5*8.1OR290003300161F290*314.5*8.1OR300003300161F300*324.5*8.1OR310003300161F310*334.5*8.1O***0003300161F320*344.5*8.1OR330003300161F330*354.5*8.1OR340003300161F340*364.5*8.1OR350003300161F350*374.5*8.1OR360003300161F360*384.5*8.1OR370003300161F370*394.5*8.1OR380003300161F380*404.5*8.1OR390003300161F390*414.5*8.1OR400003300161F400*424.5*8.1OR410003300161F410*434.5*8.1OR420003300161F420*444.5*8.1OR430003300161F430*454.5*8.1OR440003300161F440*464.5*8.1OR450003300161F450*474.5*8.1OR460003300161F460*484.5*8.1OR470003300161F470*494.5*8.1OR480003300161F480*504.5*8.1OR490003300161F490*514.5*8.1OR500003300161F500*524.5*8.1北京市中兴利得科技有限公司***经销美国派克PARKER密封件。PAREKR液压系列密封类型：防尘圈A1、A5、A6、A8、AD、AF、AG、AH、AM、AY，活塞杆密封B3、BS、BA、BD、BR、BU、C1、CR、M2、M3、OD、ON、JS、Q3、R3；活塞密封B7、C2、CQ、CP、KR、M4、OE、OG、OK、CT/Y3、ZW、ZX、JK、ZC、ZP、导向元件F1、F2、F3、FC、FR,旋转密封OR、OQ、RS、RI等。PARKER气动系列密封类型：防尘圈A2；气动活塞杆密封C1、E5、E8、E9、EL、EM、EP、EU、Z9、EF、ET；气动活塞密封C2、E4、MK、OA、PZ、Z5、Z7、Z8、DE、DK、DP、EK、DR；缓冲密封件PP、V6型等及O型圈。美国原装***，产品齐全，备有库存，价格优惠。欢迎来电订购！)
