无油润滑或少油润滑,造用于无法加油或很难加油的场所,可在使用时不保养或少保养. 耐磨性能好,摩擦系数小,使用寿命长.
有适量的弹塑性,能将应力分布在较宽的接触面上,提高轴承的承载能力. 静动摩擦系数相近,能消除低速下的爬行,从而保证机械的工作精度.
能使机械减少振动,降低噪音,防止污染,改善劳动条件. 在运转过程中能形成转移膜,起来保护对磨轴的使用,无咬轴现象.
对磨轴的硬度要求低,未经调质处理的轴都可使用.从而降低了相关零件的加工难度. 薄壁结构,质量轻,可减小机械体积.
钢背面可电镀多种金属,可在腐蚀介质中使用;目前已广泛应用于各种机械的滑动部分,例如:印刷机、纺织机、烟草机械、微电机，汽车、摩托车与农林机械等等。 |
