Miniature bearing grease performance indicators of a lot, mainly colloidal stability (
Oil)
, mechanical stability,
100000 shear test, lengthen working cone into the degree of value)
And oxidation stability, the three indicators comprehensive results, is bearing life.
Running in the bearing grease of mechanical force damage, make the fiber of thickener rupture shorter, reduce the ability to maintain the structure of the grease, the consistency of change, if consistency change very assembly from the working surface erosion phenomenon, at the same time in the operation of grease will be influenced by temperature, base oil can produce evaporation and reduce or part of the base oil as lipid gel break points loss to reduce fat oil content of the oil, also has the potential to produce the oxidation.
For bearing grease, therefore, if the work within fat base oil content lower than 60%
When 70% (
The base oil loss due to evaporation or points of oil - 30%
40%)
Lose lubrication ability will be reduced and even cause the failure of bearing operation, at the same time of consistency and oxidation of fat and bad work more will affect the running of the bearing.
