NOTICE! Gear unit damage
Failure to comply with this will result in damage to the gear unit.
• Overheating of the gear unit due to reduced cooling power because of deposits (fouling).
• The internal water cooling (cooling coil) must be cleaned or replaced if deposits are found.

To check the cooling coil, the coolant feed must be shut off and the pipes disconnected from the
cooling coil. If deposits are apparent on the inner wall of the cooling coil, the deposits and the coolant
must be analysed.
If a chemical cleaner is used, it must be ensured that the cleaning agent does not attack the material
of the cooling coil (copper pipe and yellow brass fittings).
Please contact the NORD Service department.

5.2.15 Bearings in the gear unit
As standard, all bearings in the gear units are lubricated with an oil bath. For installation positions
where this is not possible, or in case of reduced oil levels, lubricant circulation is used.
Exceptions to this are gear units SK 5..07 bis SK 6..07 in installation position M5/M6. In this
installation position, the upper bearings are lubricated with grease.
Please contact the NORD Service department for replacement of the grease in the roller bearings.
Recommended grease: Petamo GHY 133N - Klüber Lubrication (7.3.1 "Roller bearing greases").
