What is greasing?
Greasing is used to reduce the friction of the durability by applying a grease between two surfaces which are moving past each other.

The purpose of greasing:
 Reducing friction
 Reducing traces of wear
 Heat removal
 Removal of harmful particles
 muffling vibrations (through eccentricity noise)
 Corrosive barrier
 sealing

Durability
Appearances:
 Two materials sticking together
 Pit formation
 Abrasive durability
 Corrosive durability

Cure:
 Surface Protection and the seperation layer
 Fatigue – Choice of materials
 Filtering
 Additives in the durability (Oil)
