  BNR/BER超高速角接触球轴承是经过优化设计的一种高速轴承。此系列可以满足轴承的高速度性能、增强运转精度、提高系统刚度、降低热量生成、降低噪音和振动是轴承行业面临的难题。在高速加工中心、铣床、内部磨床以及木工机床等应用场合,具有很高的可靠性,以及卓越的运行效果。采用BNR/BER设计的轴承有利于轴承承受径向载荷以及一个方向上的轴向载荷。轴承大尺寸球状滚动体数量更多,这也有利于轴承承受更重的载荷。轴承的外圈引导的保持架是用纤维增强酚醛树脂生产而成的,这是为了更好的为球状滚动体滚道接触区域提供润滑。保持架和外圈之间的引导间隙经过优化后,在高速运行下的性能明显提高。内圈和外圈处的倒角形状经过优化后,安装精度得到了改进,改进情况取决于轴承系列和尺寸。这样不仅简化了安装程序,而且降低了对相关部件造成损坏的风险性。BNR/BER超高速角接触球轴承的开式密合度使得轴承具有很高的速度性能。
  
  高速铣床、加工中心和磨床等机床应用场合对定位精度有很高的要求,而且需要产生很少的热量。BNR/BER超高速角接触球轴承能满足上述要求,在高速运行下具有很高的刚度,使之成为这类应用场合的优质解决方案。
