What is tribology?
Tribology is the study of science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is a branch of mechanical engineering and materials science.

Tribology’s economic and commercial impact is vast. The science reduces energy use, lowers the cost of maintenance and replacement, develops new technology, and solves resource problems, such as the lack of clean water. Proper tribological procedures save an estimated 1.3% to 1.6% of a nation’s gross domestic product—a savings of hundreds of billions of dollars (U.S. currency) in larger countries. Virtually every nation has realized it cannot afford to overlook the economic, industrial, and commercial advantages of tribology. Consequently, tribology is a science that is constantly being advanced by thousands of researchers around the world. Lubrication engineering is the practical application of that science, generally in the development of lubricants and their proper usage and maintenance. 

What is STLE? 

STLE, one of the largest professional societies in the field, serves 15,000 industry professionals worldwide.

To advance the science of tribology and the practice of lubrication engineering in order to foster innovation, improve the performance of equipment and products, conserve resources and protect the environment.

Online webinars, education courses and professional certification programs offer opportunities for continuing education to enhance your career and create value for your company.


STLE organizes, supports, co-sponsors and hosts meetings to provide the tribology and lubrication communities an opportunity to network, exchange ideas and information.

Educating technical professionals to compete in the global business environment is STLE's core mission of serving as a trusted provider of education and a workforce development partner.

STEM programs, scholarships and student outreach programs are a cornerstone to communicating the value of tribological innovations to the next generation of scientists and engineers.
