ANTI-WEAR / ADDITIVE
- Anti-wear (AW) Agent
- Additive that is active in preventing damage caused by occurrence of solid phase welding between sliding surfaces without local surface melting.
- Purpose is to prevent abrasion and metal to metal contact.
EXTREME PRESSURE (EP) ADDITIVE
Chemical compound imparting extreme pressure characteristics to a lubricant with the objective of reducing wear under conditions where rubbing or sliding accompanies high contact pressures, as in heavily loaded gears.
WATER RESISTANT
- The resistance of a lubricating grease to adverse effects due to the addition of water to the lubricant system.
- Water resistance is described in terms of resistance to washout due to submersion.
OXIDATION STABILITY
- Ability of a lubricant to resist oxidation and deterioration resulting from high temperatures and / or exposure to air.
- Purpose is to prolong the life of a grease.
TIMKEN OK LOAD
Maximum load a lubricant will withstand without failure due to breakdown of the lubricant film, as determined on the Timken EP Lubricant Tester. In other words measure of the extreme pressure properties of a lubricant. Timken OK load is the heaviest load that can be carried without scoring.DROPPING POINT
The dropping point of a particular type of grease is the temperature at which the first drop of liquid separates when the grease is heated under prescribed conditions.
