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.
Noise
The geared motors are certified for a wide range of installation and operating conditions.
Conditions such as rigid or vibration-isolated foundation design influence noise emission,
sometimes significantly.
The circumferential velocity of the motor pinion has a significant influence on the additional
gearbox noise. This is the reason that higher speeds or low transmission ratios result in
higher noise.
Note
External noise
Noise not generated by the gearbox but emitted from it is not taken into consideration.
Noise emitted by the drive and driven machines or the base is not taken into consideration.
