High viscosity grease with solid lubricants
SKF LGEM 2 is a high viscosity, mineral oil based grease using a lithium soap. Its content of molybdenum disulphide and graphite provides extra protection for harsh applications subjected to high loads, heavy vibrations and slow rotations.
High oxidation stability
Molybdenum disulphide and graphite provide lubrication even if the oil film breaks down
Typical applications:
Rolling element bearings running at low speed and very high loads
Jaw crushers
Track laying machines
Lift mast wheels
Building machines such as mechanical rams, crane arms and crane hooks
