Maxigras 102 Serie
Lubricating grease formulated with the latest generation Calcium Sulphonate Complex thickener and high viscosity oil.
Specially designed to work in all types of mechanisms under extreme situations.
APPLICATIONS:
Lubrication of bearings, joints, splined shafts, drive shafts, chains, guides, couplings, gears, etc., and generally any mechanism working under the most severe conditions of loads and vibrations, even in the presence of aggressive humid, saline and alkaline environments, as well as at very high temperatures.
-Pellet pulverisers.
-Rolling mills in the steel industry.
-Paper and textile industry.
-Public works, construction, mining, cement...
-Naval sector,
-Etc.
MAXIGRAS 102 is available in different grades of hardness (NLGI consistencies):
-Grade 2 is the usual grade for manual greasing and centralised greases that allow the use of greases of this grade 2 consistency.
-Grade 1.5 is used in centralised lubrication systems that allow the use of grade 2 greases, but which due to their special configuration (length, elbows, pipe diameter, etc.) require a slightly higher fluidity.
-Grade 1 is used in centralised and manual greasing systems where softer greases are required. This grade is preferred for dished tooth couplings.
-Grade 0 is recommended for cables, chains and gears on ship decks and harbour machinery, as well as for grease lubricated closed sump gears and centralised greasing with very fluid greases.
PROPERTIES:
- Excellent performance under extreme conditions and shock loads. High EP capacity.
- Protection against corrosion and oxidation.
- High resistance to washing in hot and cold water, both fresh and salt water.
- Excellent adhesion, high resistance to dripping/runoff.
- Excellent pumpability at low temperatures.
- Thanks to its complex thickener technology, it offers a high capacity for continuous work at high temperatures, providing an excellent consistency recovery on cooling.
- Excellent mechanical resistance to continuous stress, minimal consistency changes.
