 Abbreviations  Definition of Terms Relating To Lubricating Grease
 
 
DROPPING POINT
The drop point of a particular type of grease is that temperature at which the first drop of liquid separates when the grease is heated under prescribed conditions.
 
TIMKEN OK LOAD
Maximum load a lubricant will without failure due to breakdown of the lubricant film, as determined on the TIMKEN Ep Lubricant Tester. In other words, Timken OK load is the heaviest load that can be carried without scoring.
 
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 applications.
 
MOLYBDENUM DISULPHIDE [MOS2] AND GRAPHITE
A very effective solid lubricant that is used for back-up lubricant in extra hih temperature and high load applications.
 
PENETRATION
The measure which indicates the softness or hardness of a grease. The NLGI has developed a numerical scale to classify the consistency of grease based upon their worked 60-stroke penetration values.
