聚四氟乙烯档圈

聚四氟乙烯档圈提供任意规格白垫档圈。挡圈没有密封功能，其作用是保护和防止密封件挤出。挡圈经常和弹性密封圈一起安装在沟槽内一特别适合与O形圈、星形圈一起使用。由于紧紧地将挡圈安装在沟槽中，故挡圈能防止弹性密封圈受压后被挤入间隙中。挡圈一般具有矩形的截面，特别符合相应的O形圈、星形*圈沟槽尺寸。设计·挡圈，型号6U，没有切口这种没有切口的挡圈，优先使用在与O形圈、星形圈一起使用的活塞杆等内圈密封的动态、静态密封中，特别是当O形圈在高压力和高温情况下发生变形时。当挡圈使用在外圈密封时，需要开放式的沟槽。但是其中有一种没有切口的挡圈例外，它可以被安装在封闭的外圈密封沟槽中，这种挡圈的型号是BUZ。与标准的挡圈相比较，这种特殊的挡圈有不同的外径和内径。如果需要，可以按照客户图纸需要提供这种挡圈。·挡圈，型号BG，有切口有切口的挡圈，通常和O形圈一起运用在静态、往复运动的外圈密封中。对于内圈密封运用中，有切口的挡圈经常运用于两种情况下：1、没有切口的挡圈不能被安装入沟槽；2、不能设计成开放式沟槽。有切口的挡圈，切口的角度为30°或者45°这样能够使O形圈得到保护。·挡圈，型号S户，螺旋型螺旋型的挡圈由两个螺旋状的线圈组成。螺旋线圈的未端被切成一定的角度。这种挡圈的设计可以与O形圈一起运用于静态、往复运动的内、外圈密封中。这种螺旋型挡圈在实际应用中的特别优点，在于当有巨大的温度波动时，螺旋型的挡圈能够毫无困难地通过螺旋状的延长和收缩，补偿尺寸公差的变化。·挡圈，型号BG，有切口有切口的挡圈，通常和O形圈一起运用在静态、往复运动的外圈密封中。对于内圈密封运用中，有切口的挡圈经常运用于两种情况下：1、没有切口的挡圈不能被安装入沟槽；2、不能设计成开放式沟槽。有切口的挡圈，切口的角度为30°或者45°这样能够使O形圈得到保护。·挡圈，型号S户，螺旋型螺旋型的挡圈由两个螺旋状的线圈组成。螺旋线圈的未端被切成一定的角度。这种挡圈的设计可以与O形圈一起运用于静态、往复运动的内、外圈密封中。这种螺旋型挡圈在实际应用中的特别优点，在于当有巨大的温度波动时，螺旋型的挡圈能够毫无困难地通过螺旋状的延长和收缩，补偿尺寸公差的变化。常用规格一览：8x5x134x40x1.2530x35x1.556x60x1.917x20x135x40x1.2530x40x1.552x62x1.920x30x135x41x1.2532x36.8x1.553x63x1.93x6x1.2535.5x41.5x1.2532x37x1.555x65x1.94x7x1.2536x41.8x1.2532x40x1.556x66x1.95x8x1.2536x42x1.2535x40x1.558x68x1.96x9x1.2538x44x1.2535x41x1.560x70x1.97x10x1.2539x45x1.2535x45x1.562x72x1.98x11x1.2540x45x1.2536x44x1.563x73x1.98x12x1.2540x46x1.2538x43x1.565x75x1.99x12x1.2541x47x1.2538x43.8x1.567x77x1.99.5x14.2x1.2542x48x1.2540x45x1.570x80x1.910x13x1.2544x50x1.2540x50x1.571x81x1.910x14x1.2545x50x1.2540.2x45x1.575x85x1.911x14x1.2545x51x1.2545x50x1.580x90x1.911x15x1.2546x52x1.2550x55x1.585x95x1.912x15x1.2548x54x1.2553x63x1.590x100x1.912x16x1.2549x55x1.2555x60x1.595x105x1.913x18x1.2550x55x1.2558x63x1.5100x110x1.913x19x1.2550x56x1.2560x64.8x1.5105x115x1.914x18x1.2555x60x1.2560x65x1.5110x120x1.915x18x1.2560x65x1.2562x72x1.5115x125x1.915x19x1.2565x70x1.2565x70x1.5120x130x1.916x19x1.2570x75x1.2570x74.8x1.5125x135x1.916x20x1.2575x80x1.2570x75x1.5130x140x1.916x21x1.2580x85x1.2570x80x1.5131x141x1.918x22x1.2585x90x1.2575x79.8x1.5132x142x1.920x24x1.2590x95x1.2575x80x1.5135x145x1.920x25x1.2595x100x1.2580x90x1.5140x150x1.920x30x1.25100x1.5x1.2585x90x1.5145x155x1.921x25x1.25105x110x1.2590x95x1.5150x160x1.922x26x1.25110x115x1.2595x100x1.5165x170x1.922x28x1.25115x120x1.25100x105x1.5175x180x1.922.4x28.4x1.25120x125x1.25105x110x1.5185x190x1.924x30x1.25125x130x1.25105x115x1.5190x200x1.925x31x1.25130x135x1.25110x115x1.5195x200x1.925.5x31.5x1.25135x140x1.25110x120x1.5200x215x1.926x31.8x1.25135x145x1.25112x122x1.5205x210x1.926x32x1.25140x145x1.25115x120x1.5225x230x1.928x32x1.25145x150x1.25120x125x1.5235x240x1.928x34x1.25150x155x1.25125x130x1.5245x250x1.929x33x1.25155x160x1.25135x140x1.5255x260x1.929x35x1.2514x18x1.5140x150x1.518x24x229.5x35.5x1.2521x25x1.5145x150x1.520x28x230x36x1.2522x26x1.5155x160x1.522x32x231x37x1.2523x28x1.5155x165x1.525x33x232x36x1.2528x34x1.5180x190x1.528x36x232x38x1.2529.5x36.5x1.548x58x1.930x40x232x40x2115x125x2235x250x245x55x335x43x2120x130x2240x250x250x63x340x48x2120x140x2249x265x250x65x340x50x2124x140x2250x266x255x68x342x50x2125x135x2260x276x255x70x345x53x2125x137x2264x280x255x88x348x63x2125x141x2270x280x260x70x350x58x2125x145x2280x296x260x73x350x60x2128x140x2284x300x260x75x351x63x2130x140x2296x320x264x80x353x63x2134x150x2300x316x265x75x355x63x2135x145x2316x340x265x78x358x70x2138x150x2336x360x265x80x360x70x2139.6x145x2376x400x265x85x363x73x2140x145x242x50x2.570x80x363x75x2140x150x270x76x2.570x83x367x70x2140x152x271x74x2.570x85x368x80x2140x156x290x95x2.570x90x370x80x2140x160x295x100x2.571x85x370x82x2144x160x2100x105x2.575x85x370x90x2148x160x2165x180x2.575x88x375x85x2150x160x2185x200x2.575x90x378x90x2150x162x2205x220x2.575x95x380x90x2150x166x2235x250x2.576x90x380x92x2155x165x2250x270x2.580x85.3x385x95x2160x170x2265x280x2.580x93x388x100x2160x172x2305x320x2.580x95x390x95x2160x176x2306x320x2.580x100x390x100x2164x180x2316x340x2.581x95x390x102x2165x175x2320x344x2.585x100x390x110x2170x180x2345x360x2.585x105x394x110x2175x185x2386x400x2.586x100x395x100x2180x190x2150x165x2.7590x105x395x105x2180x192x2155x170x2.7590x110x395x110x2180x194x2160x175x2.7594x100x398x110x2180x196x2165x180x2.7595x100x3100x110x2184x200x2170x185x2.7595x105x3100x112x2185x195x2175x190x2.7595x110x3100x120x2190x200x2180x195x2.7595x115x3105x115x2200x210x2185x200x2.7596x110x3105x125x2200x216x2190x205x2.7596x115x3109x125x2204x220x2200x215x2.7599x105x3110x120x2210x220x232x48x3100x115x3110x122x2210x230x235x45x3100x120x3110x125x2220x205x237x47x3101x120x3110x126x2220x236x238x48x3104x110x3110x130x2230x240x240x50x3105x120x3113x125x2234x250x240x55x3105x125x3耐磨带导向带分类：PTFE聚四氟乙烯：带铜粉配以适量添加剂等，具有耐磨，耐温，耐腐蚀的特封。酚醛夹布(电木):采用热固性线型酚醛树脂为基材，以优质棉纤维或其他纤维及其织物为增强材料，并配以适量的耐磨减摩添加剂。有优异的压缩强度、硬度、热变形温度、抗冲击性、自润滑耐磨等特性。律特士C380:纤维复合材料是由细密网状塑料、特殊热固聚合树脂和润滑添加剂组成。它具有吸收振动生能，并有极好的耐磨性能和良好的干运行特性。其颜色为绿蓝色。特开T47：此材料被推荐在低摩擦及无爬行情况下应用。它具有极强的耐磨性能，并且具有极好的耐热性和耐化学腐蚀特性。条纹网状。常用规格一览(宽度*厚度)：80x180x1.810x1.515x1.520x1.525x1.54.2x26.3x28.1x29.7x215x220x24.2x2.55.1x2.56.3x2.58.1x2.59.7x2.515x2.520x2.525x2.530x2.535x2.540x2.545x2.550x2.56.3x38.1x39.7x315x318x320x325x330x340x350x312x415x420x430x440x450x480x42
