Tribological Testing: SRV, 4 Ball Methods and Profilometer - …

4-Ball data is useful to differentiate between lubriing greases having different levels of load bearing capabilities, wear protection and friction reduction. Although these results do not necessarily correlate with real life appliions, the method has become an industry standard in comparing EP, wear and frictional functionality.
