Description

Size, Life and load rating are the most important design criteria of rolling element bearings. However, there is much more to know about bearings. Friction, thermal and electric parameters get more in the focus due to the thrive for sustainability. Noise and dynamics can also be important design parameters. And – as bearings are not alone, but implemented in systems – the loads and speeds transmitted to the bearings need to be regarded, too.

Presenter:
Dr. Hannes Grillenberger is key expert on rolling bearing fundamentals at the automotive and industrial supplier Schaeffler, with a focus on rolling element bearing noise. He joined Schaeffler’s fundamentals department in 2012 after receiving his doctorate in physics at the University of Erlangen-Nuremberg, Germany. During that time, he developed a laboratory detection method for oxygen precipitates in semiconductor silicon, measuring their growthin situat 1,000 C using high-energy X-rays.Since joining Schaeffler, Grillenberger has worked on simulation methods for rolling element bearing friction, cage strength and noise, the latter of which has been his primary area of focus for the past five-plus years. He holds several patents and conference awards and frequently publishes journal technical papers and presents at industry conferences.
Grillenberger is currently a member of STLE’s Board of Directors and Rolling Element Bearing Technical Committee. In addition, he organizes the discussion roundtables for both the STLE Annual Meeting, as well as the Tribology Exchange Workshop co-hosted by STLE and the European Lubricating Grease Institute (ELGI). As part of STLE’s Annual Meeting, Grillenberger also is responsible for lecturing on the topic of dynamic assessment of rolling bearings during the rolling element bearings education course program, which is co-presented by the American Bearing Manufacturers Association (ABMA) and STLE.
