5.4 Lubrication
5.4.1 Forcefeed lubrication
In case of high input speeds or high peripheral speeds at the toothed systems, the splash lubrication can,
depending on the order, be supplemented by or replaced with a forcefeed lubrication.
In case of forcefeed lubrication the bearings and/or teeth situated higher than the oil level are adequately
supplied with oil by way of pipework.
The following configurations are possible:
─ External oilsupply system (fitted separately, see item 5.8.3).
Note
In case of gear units with oilsupply system, before starting the unit up all monitors must be connected
so as to be ready for operation.

Note
When operating and servicing the components of the oilsupply system, observe the operating
instructions of the components.
For technical data and control information, refer to the data sheet and/or the list of equipment.
For a detailed illustration of the gear unit and the oilsupply system, refer to the drawings in the gearunit
documentation.
5.5 Shaft bearings
All shafts are fitted in rolling bearings.
5.6 Shaft seal
Radial shaftsealing rings and Taconite seals at the shaft outlets prevent oil from escaping from, or dirt from
entering into the gear unit.
5.6.1 Radial shaftsealing rings
Radial shaftsealing rings are the standard type of seal. Radial shaftsealing 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 shaftsealing ring possible through high dust concentration.
Do not use radial shaftsealing ring in an environment with high dust concentration.
