K3N greases
WINTERSHALL Wiolub LFK 3

These greases have lithium soap as the thickening agent and mineral oil as the base oil.

They exceed the standard requirements of DIN 51825 in several important respects and are,

therefore, compatible with the specified regreasing intervals.

NOTICE

Never mix greases that have different thickening agents and base oils.

Initial lubrication

ESSO Unirex N grease is used for initial lubrication of the bearings (prior to delivery).
