Shaft seals
The shaft sealing rings on the output side prevent lubricant from escaping from the housing
at the shaft outlet and prevent pollution from entering the housing.
The optimum use of the seals depends on the ambient conditions and the lubricant being
used.
Radial shaft sealing ring
A high-quality radial shaft sealing ring is used as standard seal. The ring is provided with an
additional dust lip to protect against contaminants from outside.
Sealing ring for a longer service life (optional)
The radial shaft sealing ring with dust lip has an additional buffer axial seal towards the
inside of the gearbox. The buffer axial seal has a sinusoidal sealing lip that protects the
sealing ring from contaminations.
Sealing ring to handle increased environmental stress (optional)
The sealing ring is equipped with an additional fiber disk. In addition to the longer service life,
the disk also provides increased protection against higher environmental stress as a result of
moisture and dust.
2.3
Cooling
NOTICE
Dust deposits prevent heat radiation
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the gearbox free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80 °C, please contact Technical Support.
