Lubrication
Lubrication of guideway raceways
The guideway raceways must be lubricated (even before first use). Lubrication can be carried out by means of lubrication and wiper units.
These units are already integrated in the compact carriage LFKL..-SF. For carriages LFL..-SF and LFCL, the lubrication and wiper unit AB, is available as an accessory.
The guideway raceway is lubricated by an oil-soaked felt insert. Oil can be fed to the felt inserts via lubrication nipples in the end faces. At delivery, the felt inserts are already soaked with oil (H1 approval for the food industry), where relubrication is to be carried out an oil of viscosity ν = 460 mm2/s is recommended.
Lubrication intervals
The lubrication intervals for guideway raceways are dependent on the environmental influences. The cleaner the environment, the smaller the quantity of lubricant required. The time and quantity can only be determined precisely under operating conditions since it is not possible to determine all the influences by calculation. An observation period of adequate length must be allowed.
ACHTUNG
Fretting corrosion is a consequence of inadequate lubrication and is visible as a reddish discolouration of the mating track or outer ring. Inadequate lubrication can lead to permanent system damage and therefore to failure. It must be ensured that the lubrication intervals are reduced accordingly in order to prevent fretting corrosion.
In general, a thin film of oil should always be present on the shaft.
Lubrication of track rollers
At delivery, track rollers LFR have an initial greasing of a high quality lithium soap grease.
From LFR5204-16, the inner ring has a relubrication hole. Track rollers of smaller diameters are lubricated for life.
