注：為便于計(jì)算，在上表中提供的軸承額定負(fù)荷是以500轉(zhuǎn)/分的速度運(yùn)轉(zhuǎn)3000小時(shí)為基礎(chǔ)，即L10壽命，但較大的軸承速度卻取決于軸承的尺寸及負(fù)荷的程度，而速度有可能低于500轉(zhuǎn)/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
