The life actually required for bearings naturally varies according to the nature of the application . 轴承所需的实际寿命当然与应用的性质有关。
The relationship between the different forms of bearing instability is illustrated in fig. 11. 7 . 轴承不稳定性的各种形式之间的关系如图117所示。
The susceptor rested on a pedestal whose shaft is connected to a motor that provides rotation . 感应器安装在轴承台上，它的支架与提供旋转的马达相接。
The rotating parts consist of the rim, web, bearings, shaft, and rotor portion of the motor . 旋转部分由转子体、辐壁、轴承、轴以及马达的转子部分组成。
There will be stray torques from the leads to the detector and some frictional forces from the bearings . 接到探测器的导线和一些轴承摩擦力会产生杂散力矩。
The maximum load on a bearing should always be smaller than the relief load in order to avoid scuffing . 为了避免划伤，轴承上的最大负荷应该总是小于其卸载负荷。
When thrust must be accepted, the tapered roller bearing of the type sketched in fig. 9. 3(b) is employed . 当必须承受轴向力时，则用图93（b）所示的圆锥滚于轴承。
However, as spin speed is increased, the power required to overcome windage and bearing friction rises sharply . 但是，随着自转角速度的增加，克服风阻和轴承摩擦的功率急剧地提高。
Driving power for the cutting tool comes from the rotation of the spindle, which is a hollow shaft that rotates in bearings . 刀具的驱动力来自主轴的旋转，主轴则是一根在轴承中旋转的空心轴。
The trunnion assembly is supported by air bearings at the end of each arm and is held in position by brake shoes at each bearings . 耳轴组件的支承是每根臂末端的空气轴承，轴承上的闸瓦起定位作用。
