The influence of the dwell time and properties of oil on the breakaway friction of a U-cup rod
seal was analysed. A logarithmic correlation between the breakaway friction force and the
dwell time (in a range from 30 to 104 seconds) was found. We used oils from various viscosity
classes (ISO VG 32 …460) and chemical compositions (mineral oil, silicone oil, perfluoropolyether, polyglycol). An almost linear correlation between the dynamic viscosity and the breakaway friction was found. Among viscosity and dwell time, further properties of oil must have a
remarkable influence on the breakaway friction of rod seals. Using ellipsometry, we showed
that even a film thickness of approximately 8 nanometres can be squeezed out of the sealing
gap during dwell time.
