In the case of gear units with add­on
oil­supply system, before starting
the unit up the pressure monitor
must always be connected so as to
be ready for operation.
Depending on the order specification and application, the
flange pump may be replaced with a motor pump.
When operating and servicing the components of the oil­supply system, observe the
operating instructions of the components.
For technical data, refer to the data sheet and/or the list of equipment.
5.6 Shaft bearings
All shafts are mounted in rolling bearings.
5.7 Shaft seals
Depending on requirements, radial shaft sealing rings, labyrinth seals, or Taconite seals or Tacolab seals
are mounted at the shaft exits to prevent oil from leaking from the housing and dirt from entering it.
5.7.1 Radial shaft­sealing rings
Radial shaft­sealing rings are the standard type of seal. They are fitted preferably with an additional dust
lip to protect the actual sealing lip from external contamination.
Use in an area with much dust is not possible.

5.7.2 Labyrinth seals
Labyrinth seals are non­contacting and avoid wear to the shaft. They therefore require no maintenance
and ensure favourable temperature characteristics. They can be used only with certain transmission ratios
and minimum speeds.
Check in the spare parts drawing and the spare parts list whether the gear unit is provided with labyrinth
seals.

For reliable operation, this type of seal requires stationary, horizontal
positioning in a splash­free and relatively dust­free environment. Overfilling of
the gear unit can cause leakage, as can oil with high foam content.
To be connected
as opener or closer,
as required.
