ETM (Extreme Pressure Traction Machine)

Part code: ETMSYS
Main product features
  • Measurement of the formation and removal of anti-wear tribofilms at high contact pressures
  • Studying the influence of very high shear stresses on lubricant/material chemistry (mechanochemistry)
  • Scuffing testing of lubricants, materials and surface finishes
