Model No: GRAPHITE GREASE
GRAPHITE GREASE
Quantity :
- ROLLESTER Lithium Base with Molybdenum Disulfide Grease is an extreme pressure/antiwear grease, formulated with a lithium soap thickener and high quality mineral base oil. It contains selected additives and molybdenum disulfide (MoS2 or ‘moly’). It has outstanding extreme pressure/antiwear properties and mechanical stability. Available as NLGI grades 1, 2 and 3.
Features & Benefits
Typical Properties
- Excellent extreme pressure and antiwear properties protect heavily loaded or shock-loaded bearings and gears from wear, extending equipment life.
- Solid molybdenum disulfide provides an additional measure of residual lubrication, which protects metal surfaces against wear in applications where vibrating or oscillating movement tends to squeeze out the grease from between the surfaces.
- Lithium soap thickener ensures good mechanical stability, so the grease structure does not soften or break down in service.
- Good water resistance properties ensure the grease is not easily washed out of bearings or off gear surfaces, so ensuring optimum protection.
- Good adhesive properties ensure the grease sticks to the metal surfaces sealing out dirt and abrasive materials, and so allows longer lubricating intervals.
- Provides good protection against rust and corrosion, extending component life and relubrication intervals.
- Available in NLGI grades 1, 2 and 3 to meet the requirements of specific applications
