1. 改性聚四氟乙烯（PTFE）以及鉛（Pb ）的混合物 0.01~0.03mm，一種耐磨材料，運作過程中可形成轉移膜以保護對磨軸。
2. 銅粉層0.2~0.3mm提高PTFE/Pb與鋼板的結合強度，具有很好的承載能力和耐磨性。同時銅又是一種很好的導熱材料，可快速轉移軸承運作過程中產生的熱量。
3. 低碳鋼0.7~2.3，提高軸承的承載能力和熱轉移作用。
4. 銅/錫電鍍層，銅鍍層0.008mm，錫鍍層0.005mm，使軸承有很好的耐腐蝕功能。 |

| 應用特點 APPLICATION CHARACTER | |
1. 無油潤滑或少油潤滑，適用于無法加油或較難加油的場合，可以在使用時不保養(yǎng)或少保養(yǎng)；
2. 耐磨性能好，摩擦系數小，使用壽命長； 3. 可在-195℃～+280℃范圍內使用；
4. 走合性能好，低噪音，無污染； 5. 薄壁結構，質量輕，可縮小機械體積；
6. 在運作時能形成轉移膜，起到保護對磨軸的作用，無咬軸現(xiàn)象；
7. 對磨軸的硬度要求低，未經調質處理的軸都可使用，從而降低了相關零件的加工難度；
8. 無吸水、吸油性，熱膨脹系數小，散熱性好，尺寸穩(wěn)定；
9. 鋼背面可電鍍多種金屬，因此可在腐蝕性介質中使用，不會生銹；
目前已廣泛運用于各種機械的滑動部位，如自動化機械設備(伸縮、搖擺、滑動、彎曲、回旋、回轉部位)油壓氣缸導套、齒輪泵浦、紡織機械、自動售貨機、塑膠成型機、壓鑄機、橡膠機械、煙草機、健身器材、辦公機械、液壓搬運車、汽機車、摩托車、農林機械等。 |
