Lubrication
5.5.1
Splash lubrication
Unless otherwise agreed in the order, the teeth and bearings are adequately splashlubricated with oil. The
gear unit thus requires very little maintenance.
5.6
Shaft bearings
All shafts are fitted in rolling bearings.
5.7
Shaft seal
Radial shaftsealing rings, labyrinth seals, Taconite seals or special seals at the shaft outlets prevent oil
from escaping from, or dirt from entering into the gear unit.
5.7.1
Radial shaftsealing rings
Radial shaftsealing rings are the standard type of seal. Radial shaftsealing rings seal with contact and
are fitted with an additional dust lip to protect the actual sealing lip from exterior contamination.
NOTICE
Material damage
Destruction of the radial shaftsealing ring possible through high dust concentration.
Do not use radial shaftsealing ring in an environment with high dust concentration.

5.8
Oillevel monitoring (optional)
The gear unit can be fitted with an oillevel monitor by means of a fillinglevel limit switch. The oillevel
monitoring device has been designed for checking the oil level when the gear unit is at a standstill, prior
to operating start.
If an oillevel monitoring device is in use, it is very important that the unit is in the horizontal position.
For a detailed illustration of the gear unit and the position of the addon parts, refer to the drawings in the
gearunit documentation.
Note
For the operation and maintenance the operating manuals specified in the orderspecific annex must be
observed.
For technical data and control information, refer to the orderspecific list of equipment.
5.9
Indication of oil level
The gear unit is fitted with an oillevel indication (dipstick with MIN and MAX marks) for visual oillevel
checking at standstill. Checking of the oil level can be carried out by the dipstick when the oil has cooled
down.
For a detailed illustration of the gear unit and the position of the addon parts, refer to the drawings in the
gearunit documentation.
