5.2.12 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 ((please see chapter 7.3.1 "Roller

bearing greases")).

5.2.13 Bearings is the output flange (Option: VL2/3/4/6, KL2/3/4/6)

For agitator version gear units, re-lubrication of the bearing in the output flange is necessary. Before

re-lubrication, the grease nipple opposite to the sealing plug must be unscrewed. Grease should be

injected until a quantity of 25 g escapes from the sealing plug. After this, the sealing plug must be

reinserted and tightened. Remove excess grease.
Recommended grease: Petamo GHY 133N - Klüber Lubrication ((please see chapter 7.3.1 "Roller

bearing greases")).
