在这些轴承中，有轴角编码器，它们感受到了外面的框的转动，来保持这个东西，指向相同的方向。

And in these bearings here are shaft encoders, and they sense that the rotation that the outer housing makes in order to keep this thing pointing at the same direction.

磁轴承只传递一个方向的轴向力。

Magneto bearings transmit axial forces in only one direction.

单列角接触球轴承可承受径向，轴向或复合负荷，不过，任何轴向负载必须在一个方向。

Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.
