Lubriplate® SYNXTREME HD greases are 100% synthetic, calcium sulfonate based. This advanced technology delivers outstanding shear stability, reduced wear and excellent resistance to water and other corrosive substances. They are outstanding lubricants for all types of anti-friction bearings, which are subjected to wide operating temperature ranges. The synthetic fluid used in these greases delivers increased oxidation stability and enables them to be effective at application temperatures up to 400 °F with frequent re-lubrication intervals.
