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使用。 |
| 技术参数 |
承载压力：140N/mm2
适用温度范围：-195~+280摄氏度
滑动速度：2m/s
摩擦系数：0.04~0.20
允许PV值（干）：3.6N/mm2 .m/s
允许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。 |
