Mounting Of Parallel Linear Axis - NTN-SNR LINEAR AXIS AXC Series Manual

Linear Axis of the AXBG series can be screwed from above through
the U - shaped rail profile (Figure 3.6).
The Linear Axis of the AXF series can be mounted at plane surfaces or other Linear Axis by usage of fastening elements (Figure 3.7)
or hammer screws or hammer nuts (Figure 3.8).
In this series all profile grooves are closed and must be opened at the necessary fixing points.

Generally, the number of mounting points must be matched to the application in all types of fastening. With punctual support of the
Linear Axis, the resulting bending does not impair the function nor impair the required accuracy.

Mounting of parallel Linear Axis

Generally, we recommend the allingment of parallel Linear Axis with an assembled crossbar. This is the only safe method to reduce
tensioning and thus interference of the life time to a minimum. The mounting has be carried out according to the following steps:
1. Align the first Linear Axis (drive axis) straight and assemble it completely.
2. Align the second Linear Axis parallel and tighten only slightly.
3. Move the tables in one end position.
4. Place the traverse (or crossbar).
5. If a relevant deflection is to be expected, apply the load or simulate it.
6. Check the parallelism with the feeler gauge. If necessary insert foil sheets or correct angular position of the Linear Axis.
7. Alingn traverse (or crossbar) and fix it.
8. Loosen the mounting screws of the parallel Linear Axis, so that a slight displacement is possible.
9. Move the table to the respective mounting position and tighten the screws. Start with the end position.
10. Finally, loosen the connection to the tables completely and tighten it again.
