MP—I型金属一塑料复合自润滑轴承目前已发展成滑动轴承类的一个重要分支。它不仅具常规传统滑动轴承结构性能上的一系列优点,如特殊无油工况条件下的自润滑性,而且大批量生产时价格较低,仅为青铜轴承的50％～70％,能符合现代机械、仪器、仪表和汽车工业等对轴承的负荷、速度和环境介质多方面的特殊要求,具有广泛的应用前景。目前国外欧、美、日等经济发达国家应用MP—I类轴承占滑动轴承类的比例逐年提高,已形成数十亿美元的生产规模。国内虽起步较迟,但产品质量 MP-I metal-plastic composite self-lubricating bearings has developed into a sliding bearing an important branch. Not only does it have a series of advantages over conventional plain bearings in structural performance, such as self-lubrication under special oil-free conditions, but also lower prices in mass production, only 50% to 70% of bronze bearings, Modern machinery, instrumentation, instrumentation and automotive industry and other bearing on the load, speed and environmental media in many aspects of the special requirements, with a wide range of applications. At present, the proportion of applications of MP-I bearings in the developed countries in Europe, the United States, Japan and other developed countries has increased year by year, and the scale of production has reached billions of US dollars. Although the domestic start later, but product quality
