注:为便于计算,在上表中提供的轴承额定负荷是以500转/分的速度运转3000小时为基础,即L10寿命,但最大的轴承速度却取决于轴承的尺寸及负荷的程度,而速度有可能低于500转/分.
  
In order to make it easy for calculation, the load rating noted in the above file is based on working 3000h at the speed of 500r/m, i.e. L10 life. While the limited bearing speed is depended on bearing dimension and the real load, and the speed is possible to be under 500r/m
