* Refer to “1.2.7 Ma Direction Moment Offset Datum Position and Each Axis Moment Direction” for the
Ma direction moment offset datum position and the moment direction of each axis.
* It is the value assuming the rated life of the linear guide is 5,000km (fw: 1.5, remaining ratio 90%).
* Z and R-axes allowable moments Ma and Mb for the four-axis type should be the sum total of Z-axis
and R-axis.
