轴用斯特封


轴用斯特封
 　　轴用斯特封由一个低摩擦的 填充聚四氟乙烯阶梯环和一个橡胶弹性体（O形圈）组成，是一种活塞杆用同轴式密封圈，是单向作用元件，适用于高低速直线往复运动的高压系统油缸。由于动静 摩擦系数相近，是伺服油缸采用两个轴用斯特封可达到零泄漏，一般要和导向环配套使用，承受活塞杆的径向力，选用双唇防尘圈效果更佳。
技术数据
压力≤80MPa
速度≤15m/s
温度-54℃~+200℃(取决于O形圈复合物)
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
表面粗糙度RaRt
活塞杆表面≤0,2μm≤3μm
沟槽底面≤1,6μm≤6,3μm
沟槽侧面≤1,6μm≤16μm

优点
—抗挤出性好
—尺寸稳定，不受温度影响
—不会发生困压，因而可安装多只密封圈
—对于强冲击系统具有优异的缓冲作用
—优良的抗摩擦特性，摩擦力小，寿命长
—即使在长时间不工作后，在启动时无爬行现象
—良好的动静密封特性
—适用于直径为2500mm之内的任何活塞杆
