7.4 Servicing/maintenance/cleaning
Before starting any work on the linear unit, any electrical drives used are to be pro-
tected against accidental switching on.
All linear units are provided in the factory with the required lubricant quantities. Servicing inter-
vals are dependent on the hours run, the stressing and environmental factors. For servicing, the
guidance slots (2) should be placed in the centre.
7.4.1 Guidance shaft lubrication
Oiled felt strips are used for lubricating (cleaning) the guidance shafts. The felt strips must be re-
oiled periodically, according to the stressing, via the shaft lubrication system.
Lubrication is directly via the grease nipple. Before lubricating, clean grease and oil from the lu-
brication point. Ensure you align the grease gun axially with the flow direction of the nipple.
Recommended lubricants:
Oil with viscosity of approximately 200 mm2/s at T = 40°C e.g. SAE 90 transmission oil.
First lubrication after approx. 2000 hours run.
Next interval:
Every 1000 hours run, quantity approx. 1.5 cm3.
