MINIRAIL Options
8.2 Multi-part Guideways for MINIRAIL (ZG)
If the desired total length of the guideway is longer than the maximum length listed
in the catalogue, individual guideways can be joined together with precision butt
joints. For this configuration, the ends of the guideways are precision ground. The
offset between the individual guideways should not exceed 0.002 mm.
Take note of the numbered guidewaysat the butt joints during installation.
8.3 Push Force Dened (VD)
Demanding applications may only be possible if the guideway has a defined push
force. These parameters can bedefined by SCHNEEBERGER according to
customer specifications. Carriages and guideways arethen matched and delivered
as a set.
8.4 Height-matched Carriages (HA)
In accuracy class G1, the maximum height deviation of the carriages is ±10 µm.
This tolerance can be too large for certain configurations, for example when the
distances among the individual carriages are too small, i.e. when the carriage
spacing L
b is smaller than the carriage length L. In such cases, the tolerances can
be reduced on a customer-specific basis.
Multi-part guideways are numbered at the butt joint
