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.
