Webinar: Grease and Oil Lubricant Failure Analysis

Wednesday, August 06, 2014

12:00 PM - 01:30 PM

Join us as Dr. Paul Shiller of the University of Akron, leads us through grease and oil lubricant failure analysis.

Grease & Oil Lubricant Failure Analysis

Instructor: Dr. Paul Shiller, University of Akron

Where: STLE University, live webinar event broadcast to your computer

When: Wednesday, August 6, 2014 at 12-1:00 p.m., with optional Q&A from 1-1:30 p.m. Central Time

Cost: $39 for members, $59 for non-members


At conferences and seminars about bearings and bearing failures the talks center on the physical damage of the bearings themselves.  Very little is said about the lubricant and lubrication methods.  About 50% of bearing failures can be traced back to lubrication problems.  Some are due to lubricant choices others are due to lubricant failure.  How does a lubricant fail?  How do you determine the health of a lubricant?

This webinar will discuss failure modes of lubricants, including oxidation, degradation and contamination. The webinar will then proceed to discuss how these failure modes manifest in typical tests for used lubricants such as viscosity, acid level, water level, and contamination level.

In this discussion the webinar will introduce some common “rules of thumb” for when a lubricant has reached the end of service life and discuss their merits. 

Presenter Biography

Paul Shiller received a Ph.D. degree in Physical Chemistry from Case Western Reserve University in Cleveland, OH studying the surface reactions at fuel cell electrodes using molecular orbital methods.  He holds an M.S degree in Chemical Engineering also from Case Western Reserve University where he studied the characteristics of “Diamond-like films”.  He received a BE degree in Chemical Engineering from Youngstown State University.  He recently moved to the University of Akron as a Research Scientist in an “Open Innovation” collaborative effort between The University of Akron and The Timken Co.  At The University of Akron he will be working in the Timken Engineered Surfaces lab, which is part of the Center for Surface Engineering and Lubrication Research.  In this position he will carry out fundamental studies of lubrication additives and lubrication mechanisms with an emphasis on modeling and high-pressure properties.  Previously he worked at The Timken Company as a Product Development Specialist for lubricants and lubrication in starting in 2004.  He then moved to a position as a Tribological Specialist within the Tribology and Next Generation Materials group at the Timken Technology Center in North Canton.  At Timken he studies how the chemistry of lubricants affects bearings especially how additives can be used to extend bearing life.  Before coming to Timken he managed a polymer analytical chemistry lab at the Packard Electric division of DELPHI.  He started at Packard Electric as a quality control engineer in the ignition cable department when Packard Electric was a division of General Motors.  He was a Process Engineer on the thin film deposition processes for liquid crystal display products at PanelVision in Pittsburgh.  Paul worked as a Research Engineer at The General Tire Company in Akron studying polymer extrusion and molding and the performance of tennis balls.  He started his lubrication career as a Summer Intern at The Penn State University.

Paul has received a Professional Promise Award from AIChE and the Shell Lubricants award for Instructor Excellence from NLGI. He is also currently an Adjunct Professor of Chemistry at Kent State University.  Paul is a member of STLE, ACS, and SOR.
