STLE is an individual membership society focusing on professional, technical and scientific issues and needs. It was founded on March 3, 1944, in Chicago as the American Society of Lubrication Engineers (ASLE). From these early days, into the 1980s, the organization’s primary audience was plant engineers in charge of lubrication for production equipment at major facilities like auto plans or steel mills. Major activities were technical conferences, peer-reviewed publishing and educational activities. Today, STLE is the premier technical society serving the needs of more than 13,000 individuals and 250 companies and organizations that comprise the tribology and lubrication engineering business sector. STLE members are technical experts who research, develop and market the methods and products that make industry more successful and that enhance the well-being of people worldwide. Our members are employed by the world's leading corporations and academic institutions and by governmental agencies dealing with science and technology.
