HYBRID SYNTHETIC GREASE DGG
XL0925 is a unique 100% hybrid synthetic oil-based, hydrophobic bearing grease formulated to withstand extremely high static pressures at very low and intermittent RPM.
The blend of synthetic base oils and performance enhancing additives selected to formulate XL0925 were chosen for their individual inherent chemical and physical characteristics. Priority attributes were assigned to endurance, non-toxicity, and biodegradability in aqueous environments.
The exceptionally high base-oil viscosity index (VI) and low temperature fluidity enables XL0925 to provide efficient lubrication over a wide range of temperature, from -50°C to 200°C.
Low and intermittent bearing RPM inhibits the ability of most conventional lubricants (greases) to form a stable lubricating elasto-hydrodynamic (EHD) film. Under heavy loads, rollers will come in contact with the bearing race rings, and scoring will occur upon initial rotation, unless an appropriate boundary lubricant protects contacting
Unlike conventional lubricants, XL0925 has been designed to perform like a “lubricant sponge” releasing a non-toxic and chemically inert graphite film to be deposited on the contact areas of friction, providing the necessary lubrication to the rollers. Excess graphite will be re-absorbed into the “lubricant sponge” once the roller has passed over the surface.
XL0925 is formulated for use in sluice gates, intake gates, and any other application requiring a non-toxic, partially biodegradable, hydrophobic EP grease in high loaded bearings.
