用于精密场合的球轴承都面临着特殊性能需求这个问题,如磁盘驱动主轴,CD唱机驱动装置和高速手术钻就是其中的一些例子。通常对这些要求并不能在同一轴承上组合起来。设计者为了使轴承获得长寿命采用了耐腐蚀和耐疲劳性材料,同时能使轴承在低噪音和低振动的水平上工作。最近投入使用的精密微型轴承,是用新开发的一种不锈钢合金制成的,结束了过去多年来无此材料的历史,并满足了上述的需求。这就是说将传统轴承合金AISl44OC和AISl52100的最佳特性结合起来的高级不锈钢合金DD400。具有坚硬、耐腐蚀的440C无
Ball bearings used for precision applications are faced with the special performance requirements of this issue, such as disk drive spindles, CD player drives and high-speed surgical drill is one of the examples. Often these requirements can not be combined on the same bearing. Designers use corrosion-resistant and fatigue-resistant materials to achieve long-life bearings while enabling bearings to operate at low noise and vibration levels. The recently introduced precision miniature bearings, made of a newly developed stainless steel alloy, have put an end to the history of no such material over the years and have met these needs. This is the premium stainless steel alloy DD400 that combines the best features of the traditional bearing alloys AISl44OC and AIS152100. Has a hard, corrosion-resistant 440C without
