Note
– Ensure correct alignment of the cylinder barrel with respect to the
attachment side for the bearing block or bearing cap in accordance with
the markings you have made.
– The lubrication nipples on the slide module point towards the front.
20. Remove the stoppers or adhesive tape fixings from the assembly tools.
21. Position the assembly tool with slide module and spindle assembly on the
roller track.
22. Carefully push the first roller carriage of the slide module (with the spindle
assembly) onto the roller track, at the same time, make sure no balls spring
out of the roller carriage.
23. Repeat the procedure for the second roller carriage.
Balls that have sprung out of the roller carriages must be re-inserted in the
relevant roller carriages.
Note
New roller carriages must be lubricated before commissioning the spindle
axis (
 Chapter 4.4.4 on page 41 ). Non-compliance can lead to
unlubricated operation, and thus failure of the spindle axis before the next
specified relubrication.
4.4.3.2 ELGA-BS-KF-120 / 150
1. Place the spindle assembly and retainer or retainer module on the work
surface with the slide module facing downwards; the lubrication nipples
face the rear.
All the spare parts required for lubrication of the roller carriage are supplied in
a fittings kit.
Note
The recirculating ball bearing guide system is pretensioned. Individual
balls can therefore easily slip out and become lost when pushing the roller
carriages off the assembly tool.
The roller carriages must remain on the assembly tool during the mounting
of the lubrication spare parts from the fittings kit.
Note the alignment of the roller carriage 2 on assembling!
The ground sides of the roller carriage

must be installed facing the stop
