1、聚四氟乙烯与亲油性纤维混合物0.01-0.03mm
2、不锈钢背0.7-2.3mm | |
| 产品说明 |
| SF-1SS不锈钢材料为基体，表面涂喷PTFE组成的高耐蚀、耐磨轴承。该材料特别适应强酸、强碱、轻载中低速的场合，其耐磨性能明显优于单体PTFE轴套和石墨轴套。目前该产品已广泛用于化工酸碱流量计、泵、阀以及海洋工业中耐腐蚀滑动的部位 |
| 技术参数 |
最大承载压力：100N/mm2
适用温度范围：-195~+280摄氏度
最高滑动速度：2m/s
摩擦系数：0.03~0.18
允许最高PV值（干）：3.0N/mm2 .m/s
允许最高PV值（油）：40N/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。 |
