三层复合自润滑材料是以塑料为表面层、青铜为中间层、钢背为基体的新型自润滑材料，可替代各种铜套、铜瓦、导轨、垫片等滑动磨擦零件，具有抗压强度高、摩擦系数小、尺寸稳定性好、可降低噪音、减少振动、节油节能、降低成本、提高使用寿命等优点。
I型产品是一种无油润滑材料，适用于轻负荷、调整≤20m/s,使用温度为-195oC - +270oC 。
II型产品是一种边界润滑材料，适用于重负荷、低速≤2.5m/s,使用温度为-40oC - +120oC 。
Three layer complex self-lubrication material is new type self-lubrication material with plastic as surface layer,bronze as medium layer and steel as base.It enables to replace various sliding friction parts as rim sleeve,copper bush,guide track and spacer,owns the advantages of high compressive strength,small friction factir,good dimension stability,noise reduction,shock absorption,fuel economy,energy saving,lower manfacture cost and long use lifte.
I type product is akind of no oil lubrication materil ,suitable for light load with high speed of no less than 20 m/s and service temperature form -195 to 270oC
II type product is kind of boundary lubrication material, suitable for heavy load with low speed of no more than 2.5 m/s and service temperature from -40 to 120oC
