是以钢板为基体，中间烧结球形青铜粉，表面轧制聚四氟

乙烯和混合物卷制而成。它具有摩擦系数小、耐磨、抗腐

蚀性好和无油润滑的特点。能降低成本、缩小机械体积、

避免咬轴现象和降低噪音等优点。产品已广泛应用于各种

机械的滑动部位, 例如：印刷机、纺织机、烟草机械、汽

车、摩托车与农林机械等。

产品介绍Product introduction

参 数

It is wall wrapped bushing made of triple layer composites material which be consisted of a steel backing, a sintered porous bronze particles interlayer and calendared and mixture as surface layer, It is of low friction coefficient, anti-wear, anti-corrosion and can be used without oil, or only a trace of oil if needed. Moreover, it is of low cost, low vibration and low noise, compacted and light. It is widely applied in various sliding articles of different kind of machines, such as textile machines, tobacoo machines, hydraulic vechicles, antomobiles, agriculture and forests machinese and soon.
