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，0.20-0.3mm，提高PTFE/Pb与铜板层的结合强度，具有很好的承载能力和耐磨性。较高的导热系数可迅速转移运作过程产生的热量。
3. 铜基板0.7~2.3，提高轴承的承载能力和热传递，且有更好的耐腐蚀能力。 | |

除了与SF-1相同的优点外，还具有以下特性：
由于铜本身具有其自润性能，所以可用于需长时间工作而无法停机维修的部位，具有比SF-1更好的抗腐蚀性能。广泛运用于弱酸强碱场合、港口机械、船舶机械、冶金钢铁工业，连铸机方坯滚道、高温炉钢环部位、水泥灌浆泵和螺旋式输送机上。它可以在外部组合钢套，或制成翻边，端面、内孔同时摩擦使用。 |
