产品简介

1.嘉兴创诺JF800双金属轴承是以优质低碳钢背为基体的表面烧结铅锡青铜合金材料,经数次高温烧结和致密轧制而成铜、钢一体的双金属带材卷制而成。该产品在铜铅合金中最强的一种,应用场合十分文广泛,最适合于承受中速、高冲击载荷的衬套、止推垫圈等多种类用途。 由于基体稳定为低碳钢材料,所以对轴套的外径加工精度有了保障,而且在产品装入座孔后不需要螺钉固定,依靠过盈配合就能防止走外圆现象。内表合金层化学成份的改变能满足不同承载压力,不同使用温度,不同滑动速度的要求,摩擦面在生产中设计出不同结构的油槽、油穴能满足不同加油方式的要求,并能防止咬轴现象,适应不同润滑条件。 广泛应用于汽车发动机,摩托车离合器,轻工机械,工程机械。 合金层材料   CuPb10Sn10 或 CuSn6Zn6Pb3等 最大承载压力    65N/mm2  最高使用温度  260 摄氏度 合金层硬度   (70~100)HB
