Installation Guide Linear Modules
Remove the old grease from the guide shafts with a soft cleaning cloth or paper towel. If necessary, use
a grease-dissolving agent (e.g. benzine).
Move the moving part of the guide back and forth several times so that the bearings are also degreased.
Repeat point 1.
Note: Disassembly of the guide or removal of the guide shafts from the bearings is generally not
necessary.

10.2.3 Linear Ball Bearings

Dismantle guide shafts and seals according to chapter 8.1.
Clean linear ball bearings with a soft disposable paper, possibly with the aid of a grease-dissolving
cleaning agent (e.g. benzine).

10.2.4 MagSpring

Carefully pull the slider out of the stator.
Caution! Large magnetic attraction forces (observe warning notes from p. 5)! If necessary, cover nearby
iron structures with non-magnetic material (e.g. wood).
Clean the slider and stator with a soft disposable paper, ideally with the aid of LU06 cleaning spray
(alternatively benzine or alcohol).
Lightly grease the slider with LU02.

10.3 Lubrication

10.3.1 Plain Bearings

The plain bearings used have built-in solid lubricants which allow dry running. The following limiting factors
must be taken into account:
At speeds above 1 m/s, wear increases disproportionately.
The load on the individual plain bearings is strongly related to the overhang or the maximum stroke. The
greater the stroke, the greater the load on the plain bearings due to the leverage effect.
The greater the transverse load or, in the horizontal case, the load mass on the connecting part of the
moving guide part, the greater the leverage effect or the load on the slide bearings.
The above points naturally also apply to the operation of an SM01 guide with grease lubrication. However,
the grease film greatly reduces the sliding friction at higher loads and speeds, thus enabling a significantly
longer service life and generally permitting higher operating values in terms of speed and transverse loads.
Basically, dry running should only be considered under the following conditions:
Conditions for Dry Running
Stroke range
Velocity
Transverse load
In vertical applications without transverse load, larger strokes can also be operated in dry conditions.
When operating with grease, it should be noted that the relubrication intervals are strongly dependent on the
operating and ambient conditions. In addition to the drive-related loads in the form of stroke kilometers,
speeds and surface pressure, the ambient conditions such as temperature, humidity and general
contamination also play a decisive role. It is therefore advisable to inspect the specific application regularly
and to determine the relubrication intervals from this. The inspection intervals can be extended in stages.
The recommended lubricating grease LU02 is largely resistant to water and steam. Nevertheless, in
applications where the guides are regularly wet cleaned, the lubrication intervals should be shortened
accordingly. If the cleaning process or the cleaning agents include a targeted removal of the lubricating
grease on the guide rods, relubrication is necessary after each cleaning process.
Relubrication is carried out according to the following instructions:
Remove the old grease from the guide shafts with a soft cleaning cloth or paper towel. If necessary, use
a grease-dissolving agent (e.g. petroleum ether).
