Abstract: Abstract Hydraulic cylinders are preferred if a large power density and high dynamics are required because of the low mass which has to be accelerated. Maybe the most critical machine element in fluid power devices is the rod seal. A failure leads to a contamination of the environment and the friction is dominated by the seals. A test rig was developed to measure the seal friction at high accelerations and velocities. In an experimental study the influence of acceleration, sealed pressure and temperature was captured for a polytetrafluoroethyle...
