The paraffin was used to modify cast nylon material for cranes telescopic boom shder, and the impacts oi different paraffin content on the dry friction and wear properties of the cast nylon material were researched by using MRH- 3 high-speed ring block friction and wear testing machine and RFT-IlI reciprocating friction and wear testing machine. The results show that：filling paraffin can improve mechanical properties, the friction and wear properties of the casting nylon material significantly. When paraffin decreasing first and then increasing. content is increased, the friction coefficient of cast nylon material presents the trend of There are optimal added amount, making the friction coefficient and the wear quantityto minimum.采用石蜡对起重机伸缩臂滑块用的浇铸尼龙材料进行改性，用MRH-3高速环块摩擦磨损试验机和RFT-Ⅲ往复式摩擦磨损试验机，研究不同石蜡含量对浇铸尼龙材料干摩擦磨损性能的影响。结果表明：石蜡的填充对改善浇铸尼龙材料力学性能和摩擦磨损性能有显著作用；石蜡含量的增加，浇铸尼龙材料的摩擦因数呈现先下降后上升的变化趋势，存在最佳的添加量，使材料的摩擦因数和磨损量最低。
