U型/Y型圈


MA21/NBR90
MA21/NBR90
MA21型活塞/活塞杆用U形圈
标准材料MA21:丁腈橡胶NBR90
形状:    MA21:带有切角小于45°对称密封唇的丁腈橡胶U形圈。MA22:带有直切角对称密封唇的丁腈橡胶U形圈。
应用范围:轻载荷及中等载荷的液压、气动往复运动环境。已广泛应用于各工业领域,如行走机械、轻工机械、农业机械、注塑机械、叉车、起重机、汽车、林业和采矿机械等。在恶劣的工作条件下,也具有良好的机械特性。在聚氨酯材料达不到工况下(如水中等)被应用,尤其在气动应用的场合被广泛使用。
作用:    MA21 型U 形圈具有对称密封唇形式,可用作活塞和活塞杆密封。密封效果来自于它本身的预加负载,以及在安装时密封唇的压缩。在运行时,系统的压力增大了密封的径向机械接触力。
若用在活塞密封,MA21型会采用背对背的设计和安装型式。两个密封件中间应使用导向带,最好两条,以防止活塞的偏摆对密封圈及缸壁的磨损。
优点:    MA21型密封圈具有:-良好的抗挤出性能-尤其是在产生弯曲和拉伸时,能具有抗撕裂特性-非常便于安装-对重载和活塞杆弯曲没有影响
安装:    MA21型密封圈的安装,请参照本手册的安装说明。
介质:    石油基液压油、难燃液压油、环保安全液压液(生物油)、水和其它,取决于密封圈材质。
使用条件:压力: MA21:≤ 16 Mpa / 160 Bar (加挡圈可达15Mpa / 150Bar) 温度: MA21: -30℃~+100℃         运动速度:MA21:≤0.5 m / s
备注:    以下列出的带粗体的规格为标准规格。它们是仓库常备产品或可在短时间内供货。不带粗体的规格为仓库非常备产品,在定量不大的情况下也可能短期供货。如所需的产品超出标准的使用条件,以其它橡胶为材料的产品也可供货。
