4.3.2 set up method
1. Move the machine element to the point of the rack where the rack topography is at a medium value
(refer to chapter 4.1).
2. Follow the procedure below (case 1 or case 2 depending on your application).
Case1: rack perpendicular to KRPX fixing face
Install the KRPX on the machine frame.
Move* the KRPX in the Y axis direction to set the
pinion in contact with the rack. Make sure that the
pinion teeth reach their end position in the rack
teeth (mesh without backlash).
Notes:
The reference surface for the movement can be
the key way or the KRPX ground front face
Adjust the KRPX in the -Y axis direction of a value
of tb1 given in the table below.

Case 2: rack parallel to KRPX fixing face
Use ground adjustment place
Prerequisites:
The penpandicularity tolerances have been set up
following upper chapter 4.2
The adjustment plate thickness has been defined
with t = a – b1 + tb1.
Checking method:
Mesure the distance "a"
Mount the KRPX on the machine with its
adjustment plate.
Check the tooth radial clearance tb2 (see next
chapter).
