HYBRID SYNTHETIC GREASE DGG
XL-0925 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 XL-0925 were
chosen for their individual inherent chemical and physical characteristics.
Priority attributes were assigned to endurance,
non-toxicity, and biodegradabilityin
aqueous environments.
The exceptionally high base-oil viscosity index (VI) and low temperature
fluidity enables XL-0925 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
metallic surfaces.
Unlike conventional lubricants, XL-0925 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.
XL-0925 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.
