产品说明
|
SF-1S不锈钢耐腐蚀轴承,是以不锈钢材料为基体,中间烧结球形青铜粉层,表面轧制以聚四氟乙烯为主的低摩擦材料,经过卷制成型的一种十分有效的耐腐蚀轴承。它具有耐油、耐酸、耐碱、耐海水和耐磨损的特点,表面的PTEE材料不含铅成份。在食品饮料机械、印染机械、化工机械、海洋工业耐腐蚀滑动部位最适合使用。 |
技术参数 |
最大承载压力:140N/mm2 适用温度范围:-195~+280摄氏度 最高滑动速度:2m/s 摩擦系数:0.04~0.20 允许最高PV值(干):3.6N/mm2 .m/s 允许最高PV值(油):50N/mm2 .m/s |
应用特点: |
1.PTFE、亲油性纤维的混合物在运动时可形成很好的转移膜保护对磨轴。 2.耐磨性能好,磨擦系数低。 3.走合性能好,无咬轴现象。 4.可运用于旋转、摇摆、往复运动之中。 5.耐腐蚀性能好。 6.由于不含铅,故可运用于食品机械、医疗机械等绿色环保设备。 7.典型用途:主要运用于中酸、强碱场合,例如:化工中酸碱流量计、泵、阀,印染机械、 海洋工业耐腐蚀滑动部位。 |
