About STLE

The Society of Tribologists and Lubrication Engineers (STLE) is the premier technical society serving the needs of more than 15,000 individuals and 250 companies and organizations that comprise the tribology and lubrication engineering business sector. STLE members are 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. STLE supports these distinguished men and women with a variety of professional education and certification programs.

Lubrication Engineering relates to the reduction of friction and wear between relatively moving parts. The term tribology describes the study of interacting moving surfaces. Tribology encompasses aspects of physics, chemistry, applied mathematics, metallurgy, material science, mechanical engineering, chemical engineering and applied mechanics.

Studies estimate that as much as one-third of all usable, device-produced energy is lost to friction and wear. This costs industry and consumers billions each year. In addition to energy waste, friction and wear greatly affect product reliability, maintainability, safety, life and environmental factors.
