AD防尘圈的作用是防止粉尘、污物、沙粒或者细屑进入运动的活塞杆。它可以防止刮伤、保护导向零件、延长密封件寿命。AD型防尘圈是由PTFE防尘环和O型圈组成并具有预紧力。AD防尘圈主要的优点是：·小沟槽尺寸。·***的起动和运动摩擦力，甚至在低速下也可保证平稳运动，无爬行现象。·***的滑动特点。·耐磨损，适用寿命长。·温度范围宽（使用合适的O型圈材料）。·极耐化学介质（配合适当的O型圈材料）。·可提供***大至直接2500mm的产品。4*8.8*5.5AD004005200591A5*9.8*6.5AD005005200591A7*11.8*8.5AD007005200591A8*12.8*9.5AD008005200591A10*14.8*11.5AD010005200591A12*18.8*13.5AD012005200591B14*20.8*15.5AD014005200591B15*21.8*16.5AD015005200591B16*22.8*17.5AD016005200591B18*24.8*19.5AD018005200591B20*26.8*21.5AD020005200591B24*30.8*25.5AD024005200591B25*31.8*26.5AD025005200591B26*32.8*27.5AD026005200591B28*34.8*29.5AD028005200591B30*36.8*31.5AD030005200591B32*38.8*33.5AD032005200591B35*41.8*36.5AD035005200591B37*43.8*38.5AD037005200591B38*44.8*39.5AD038005200591B40*46.8*41.5AD040005200591B42*48.8*43.5AD042005200591B45*51.8*46.5AD045005200591B48*54.8*49.5AD048005200591B50*56.8*51.5AD050005200591B52*58.8*53.5AD052005200591B55*61.8*56.5AD055005200591B56*62.8*57.5AD056005200591B58*64.8*59.5AD058005200591B60*66.8*61.5AD060005200591B63*69.8*64.5AD063005200591B65*73.8*67.0AD065005200591C70*78.8*72.0AD070005200591C75*83.8*77.0AD075005200591C80*88.8*82.0AD080005200591C85*93.8*87.0AD085005200591C90*98.8*92.0AD090005200591C95*103.8*97.0AD095005200591C100*108.8*102.0AD100005200591C110*118.8*112.0AD110005200591C120*128.8*3.53AD120005200591C125*133.8*3.53AD125005200591C130*138.8*3.53AD130005200591C140*148.8*3.53AD140005200591C150*158.8*3.53AD150005200591C155*163.8*3.53AD155005200591C160*168.8*3.53AD160005200591C170*178.8*3.53AD170005200591C175*183.8*3.53AD175005200591C180*188.8*3.53AD180005200591C185*193.8*3.53AD185005200591C190*198.8*3.53AD190005200591C195*203.8*3.53AD195005200591C200*208.8*3.53AD200005200591C210*218.8*3.53AD210005200591C220*228.8*3.53AD220005200591C225*233.8*3.53AD225005200591C230*238.8*3.53AD230005200591C240*248.8*3.53AD240005200591C250*258.8*3.53AD250005200591C260*272.2*5.33AD260005200591D270*282.2*5.33AD270005200591D280*292.2*5.33AD280005200591D290*302.2*5.33AD290005200591D300*312.2*5.33AD300005200591D310*322.2*5.33AD310005200591D320*332.2*5.33AD320005200591D330*342.2*5.33AD330005200591D340*352.2*5.33AD340005200591D350*362.2*5.33AD350005200591D360*372.2*5.33AD360005200591D370*382.2*5.33AD370005200591D380*392.2*5.33AD380005200591D390*402.2*5.33AD390005200591D400*412.2*5.33AD400005200591D410*422.2*5.33AD410005200591D420*432.2*5.33AD420005200591D430*446.0*6.99AD430005200591E440*456.0*6.99AD440005200591E450*466.0*6.99AD450005200591E460*476.0*6.99AD460005200591E470*486.0*6.99AD470005200591E480*496.0*6.99AD480005200591E490*506.0*6.99AD490005200591E500*516.0*6.99AD500005200591E600*616.0*6.99AD600005200591E630*646.0*6.99AD630005200591E680*700.0*8.40AD680005200591G700*720.0*8.40AD700005200591G800*820.0*8.40AD800005200591G900*920.0*8.40AD900005200591G1000*1020*8.40AD100Q05200591G1300*1320*8.40AD130Q05200591G)
