Grease penetration class

Maximum weight in Kg or Lbs. Grades 1 through 4 are often used in rolling contact bearings. However, this test has very limited relevance to service performance. This is because the sulphur level alone does not provide enough information on the corrosion of metallic machine parts that can be expected. Analysis of acid values. At the same time the surrounding temperature as well as the length of the conduits or hoses is also important. An oleate is a salt or ester of oleic acid.

Like all oil, even lubricating greases are altered by factors such as time and temperature. From those values the consistency classification of lubrication grease is developed. The thickener on the other hand does not just prevent oil run-off, but constantly provides oil to the lubrication points. Determining the residual oil content provides the necessary information to decide which is the case. A lower dropping point of a used grease in comparison to a fresh grease may be caused by greases with different thickeners mixing together, the grease containing water or other foreign fluids, or the grease shearing into small particles under extreme loads. Lubrication excellence begins with training. Variations that do not affect product performance are to be expected during normal manufacture and at different blending locations.

Consider Consistency When Selecting Grease

Kinematic viscosity can also be calculated as the ratio of the dynamic viscosity to the density of the liquid. Therefore, the relubrication intervals and amounts must be adapted to the decreasing additive levels. Typical numbers of double strokes used for prolonged working are 10, and , That shade shown when viewed under transmitted light only. Lubricants are available in various forms: Several such methods are available, the most widely used being ASTM D, which describes the colors in terms of numbers. In this test, a bearing ring rotates against a stationary steel block under an applied load.

Because of the oxygen molecules contained within them, they absorb infrared light in almost the same wavelength range as the double oxygen bonds which arise through oxidation. What makes a good grease? The machined aluminium base has an integral spirit level. If the grease cannot withstand the water it may become soft or watery and the quality will drop. The right combination of base oils, thickening agents and type of additive to achieve specific lubricating grease properties requires extensive development work. Grease is formulated with up to 95 percent base oil.
