NTN-SNR LINEAR AXIS AXC Series Manual page 25

The mounting surfaces of the Linear Axis, as well as for the cross traverse should be machined in the assembly area in a single setup
or should be adjustable. It should be aimed for the straightness transverse to the moving direction (Figure 3.1) of the mounting surfaces
base tolerances e and the parallelism tolerances e

If a machining of the mounting surfaces to above-mentioned requirement are not provided or this value is exceeded by the deflection
of the cross traverse, a control of parallelism must be made and, if necessary a correction must be made.
The diagram in Figure 3.2 shows the relationship between mounting tolerances and possible dynamic load capacity.
