10 Maintenance and Test Instructions
The linear ball bearings and plain bearings of the SM01 linear modules are provided with initial lubrication at
the factory. The lubrication or inspection intervals depend primarily on the average driving speed, the
operating temperature and the general ambient conditions. The following table with the inspection intervals is
based on normal industrial, central european conditions (5-day week with 8 hours of operation per day) and
the use of the recommended bearing grease LU02.
Linear Modules with Linear Ball Bearings
Velocity [v]
v < 1 m/s
1 m/s < v < 1.5 m/s
v > 1.5 m/s
Linear Modules with Plain Bearings
Velocity [v]
v < 1 m/s
Basically, the inspection cycle of the drive unit must be shortened if there are heavy loads or deviating
conditions. These are e.g.:
•
Permanent soiling
•
Direct sunlight
•
Low humidity
•
Outdoor operation
•
Strong shocks or vibrations
•
Increased operating temperature
10.1 Inspection
The following inspections must be carried out in accordance with the inspection intervals.
10.1.1 Linear Module
Do the guide shafts have too much clearance? If yes -> Replace bearings.
Do the guide shafts show signs of wear or grooves? -> If yes -> Replace guide shafts and bearings.
Have the shaft bearings been relubricated? If no -> Clean + lubricate
Can the guide unit be moved smoothly? If no -> Align the mounting plates
10.1.2 MagSpring
Does the slider show signs of wear or grooves? If yes -> Replace slider
Does the MagSpring stator bearing show signs of wear? If yes -> Replace MagSpring
Does the MagSpring slider move smoothly? If no -> Cleaning (stator, slider)
10.2 Cleaning
10.2.1 Guide Shafts
•
Dismantle the guide shafts according to chapter 8.3.3.
•
Clean the guide shafts with a soft disposable paper, possibly with the aid of a grease-dissolving cleaning
agent (e.g. benzine).
10.2.2 Plain Bearings
SM01 modules with plain bearings for the guide shafts have the advantage that the modules can normally be
cleaned without dismantling the guides. The modules are particularly suitable for wet cleaning or cleaning
with foam cleaner. In addition, operating cases are permitted in which the modules also become wet during
operation or are operated in water. However, lubrication of the bearings is recommended and also
prescribed in certain load cases (see chapter 10.3.1).
In lubricated operation, cleaning is carried out as follows:
