Abstract. Engineering components are subjected to extreme operating conditions nowadays and this leads to higher demands with regard to design specifications. Determining the temperature rise of contact interfaces subject to surface heating is essential for controlling thermally induced failures in manufacturing processes and tribology. Scuffing involves the sudden collapse of the lubricant film and is generally regarded as resulting from thermal phenomena. In order to predict scuffing failure in ball bearings, the authors developed a temperature distribution model that leads to a critical scuffing value. The experimental and theoretical results are in good agreement with literature reports.
