accordance with the lubricant plate. This ensures that the grease is evenly distributed and
covers all surfaces. Corrosion damage is avoided.
Damage to roller bearings
Roller bearings can be damaged when kept in the same or almost the same position.
Every three months, manually rotate the rotor through five revolutions. Make sure that the
resting position of the roller bearings after the rotor has been turned is different from what
it previously had been. Use the feather key as a reference point, if present.
Apply a coat of corrosion protective compound to all accessible bare metal parts such as
the exposed shaft extension, flange or machine feet.
Apply a coat of anti-corrosion compound which provides long-term protection, e.g.
