The limits are valid for bearings before mounting under zero measuring load, and with no axial displacement of one ring relative to the other.
在测量负荷为零、而且一个套圈相对于另一套圈无轴向位移的情况下，这些限值对安装前的轴承有效。

Incremental optical electric axial Angle encoder usually adopts zero position grating providing absolute zero position in order to prevent from data fault during electricity failure suddenly.
为了防止突然断电时造成数据错误，增量式光电轴角编码器通常采用零位光栅提供绝对零位信号。

Intercrossed dynamic characteristics related to the axis are not equal to zero, which illustrates that the axial of radial-thrust hybrid bearing has a relationship with the radial of it.
