Analysis and Interpretation of the Frictional Behavior of Elastomeric Rotary Lip Seals

From a study of a large quantity of frictional data on elastomeric rotary lip seals of different designs operating under various test conditions, it has been possible to identify and quantify underlying similarities. Assuming the frictional coefficient comprises a Newtonian lubrication component and a dry or boundary friction one, the analysis allows these to be individually estimated. It has been found that these individual components have a good correlation to certain test parameters.
