Cone penetration using ASTM D requires a large volume of sample and is not normally performed on used grease samples.
Functional Properties of Grease Grease functions as a sealant to worked leakage and Grease keep out contaminants. In recent years, the noise generated by a car's chassis, engine and transmission as well as rolling and wind noise have been penetration reduced through innovative automotive technological developments.
Water resistance This is the ability of a grease to withstand the effects of water with no change in its ability to lubricate.
Bearing Grease Consistency
Grease or lubricant definition - Verstegen Grabs
To reduce the juddering, the friction coefficient between the opposing materials needed to be reduced.
Consider Consistency When Selecting Grease
Understanding technical data of SKF greases
Grease Analysis - Monitoring Grease Serviceability and Bearing Condition
