A Tacolab seal is illustrated in the diagram below:
Figure3-8:Tacolab seal
① Outer labyrinth seal ④ Labyrinth, filled with grease, can be re-
greased
② Inner labyrinth seal ⑤ Grease nipple
③ Lamellar seal
To ensure reliable operation of Tacolab seals, the gear unit must be permanently installed in
a horizontal position and not exposed to waste water. Overfilling the gear unit can result in
leaks, the same applies to oil with a high foam content.
NOTICE
Gear unit leaks due to inadequate maintenance
Leaks may develop in the gear unit if it is not adequately maintained.
Regrease the labyrinth seals at the specified regreasing intervals. The regreasing intervals
are specified in the Maintenance schedule (Page87).
Further information
The spare parts drawing and spare parts list in the complete documentation for the gear unit
specify whether or not the gear unit is equipped with Tacolab seals.

The gear unit can be equipped with the following cooling equipment depending on require-
ments:
• Fan
• Cooling coil
• Mounted oil supply system
• Separate oil supply system
When installing the gear unit, make sure that unhindered convection across the housing sur-
face is possible in order to protect the gear unit against overheating.
If you are using a separate oil supply system, make sure that you observe the specific oper-
ating instructions supplied with the system.
