3.8 Lubrication
For M1..N series gear units in horizontal mounting position, splash lubrication or pres-
sure lubrication is usually used.
3.8.1 Splash lubrication
Splash lubrication is used for M1..N series industrial gear units. The oil level is low.
Parts that are not immersed in the oil bath, such as the driving gear wheel and bearing
parts, are lubricated by splashing oil.
3.8.2 Pressure lubrication
If required, pressure lubrication can be used independent of the mounting position of
the gear unit.
The gear unit is equipped with a pump (shaft end pump or motor pump). The oil level
is low and might even be reduced when compared to splash lubrication. The gearings
and bearing parts that are not immersed in the oil bath are lubricated by oil through lu-
brication lines.
Pressure lubrication is used when
• High input speeds are present and the maximum speed for the other types of lubri-
cation is exceeded (dependent on the gear unit size and variant).
• The gear unit must be cooled with an external oil-water or oil-air cooling system.
• The pitch line velocity is too high for splash lubrication or oil bath lubrication.
3.8.3 Oil bath lubrication
Bath lubrication is usually only used for some gear units of the type "M1PSF10N". All
tooth engagement or bearing points are immersed in the oil bath.
