1. 改性聚四氟乙烯(PTFE)以及铅(Pb )的混合物
0.01~0.03mm,一种耐磨材料,运作过程中可形成转移膜以保护对磨轴。
2.
铜粉层0.2~0.3mm提高PTFE/Pb与钢板的结合强度,具有很好的承载能力和耐磨性。同时铜又是一种很好的导热材料,可快速转移轴承运作过程中产生的热量。
3. 低碳钢0.7~2.3,提高轴承的承载能力和热转移作用。
4. 铜/锡电镀层,铜镀层0.008mm,锡镀层0.005mm,使轴承有很好的耐腐蚀功能。 |

应用特点 APPLICATION
CHARACTER |
1. 无油润滑或少油润滑,适用于无法加油或较难加油的场合,可以在使用时不保养或少保养;
2. 耐磨性能好,摩擦系数小,使用寿命长; 3. 可在-195℃~+280℃范围内使用;
4. 走合性能好,低噪音,无污染; 5. 薄壁结构,质量轻,可缩小机械体积;
6. 在运作时能形成转移膜,起到保护对磨轴的作用,无咬轴现象;
7. 对磨轴的硬度要求低,未经调质处理的轴都可使用,从而降低了相关零件的加工难度;
8. 无吸水、吸油性,热膨胀系数小,散热性好,尺寸稳定;
9. 钢背面可电镀多种金属,因此可在腐蚀性介质中使用,不会生锈;
目前已广泛运用于各种机械的滑动部位,如自动化机械设备(伸缩、摇摆、滑动、弯曲、回旋、回转部位)油压气缸导套、齿轮泵浦、纺织机械、自动售货机、塑胶成型机、压铸机、橡胶机械、烟草机、健身器材、办公机械、液压搬运车、汽机车、摩托车、农林机械等。 |
