These greases are specially adapted to resist impacts, vibrations, forces often encountered in heavy industry, to avoid excessive wear generated by a lubricant under degraded operating conditions. The action (chemical or physical) of the additives greatly limits seizure phenomena and thus avoids breakage of equipment.
A varied choice of thickeners but always with high viscosity base oils to effectively reinforce the lubricant film.
Combinations of EP additives and dry lubricants (Graphite, PTFE, MoS2, other metallic oxides…) allow for very high levels of performance for all extreme applications.
High-load greases are particularly suitable for lubrication of equipment such as:
- Spherical roller bearings
- Cylindrical roller bearings
- Open gears
- Crusher screen bearings
- Shredder rings and furnace crowns
- Gear-teeth couplings
- Spherical thrust roller bearings
High-load or Extreme Pressure (EP) greases have been developed mainly for heavy industry. CONDAT greases derived from these technologies are to be found in industries such as Transport/lifting and Civil works/Quarries.
- Combinations of base oils with high to very high viscosity (up to 3000 cSt) to absorb impacts and vibrations,
- Use of solid lubricants, diverse and varied, at low or high content (up to 30%),
- Combinations of liquid additives providing a tribochemical action preserving the metallic surfaces under constraint.
Their Extreme Pressure (EP) properties exceed the thresholds defined by greases for traditional use. The results obtained in Four-ball EP tests are ≥ 315kg and for some ranges can reach values of >800kg.
The high-load greases show remarkable lubricity under these extreme conditions. Thanks to a very resistant lubricating film, they avoid breakage of equipment caused by impacts and very high pressures applied locally to the bearings.
|Lubrication maintained in contact zones||Protection of metallic parts = reduction in maintenance costs|
|Excellent mechanical stability||Sealing maintained = reduction in topping up and consumption of grease|
|Reduction in temperatures observed under high forces and vibrations||Functionality ensured under limiting conditions = improves your productivity|
High-load greases are speciality greases. They are often coloured so as not to be confused with standard multi-purpose greases. The black greases contain graphite and/or molybdenum disulphide to reinforce their Extreme Pressure performance.
