Membership is available to those interested in staying current in the latest technologies, advancing their careers and making new professional connections from around the world.

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. Click here to learn more about tribology.



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.



STLE honors its 75th anniversary with a year of celebration. we begin with a salute to our founding fathers - a group of people who embody the spirit of volunteerism.

Bearing and gearbox failures: Challenges to wind turbine
(posted on July 20, 2020)

With ever increasing energy requirementsthe energy sector is seeing an unparalleled growth in renewable energy production, with wind energy in the lead. Land-based, utility-scale wind farms offer the lowest priced energy source currently available at between two to six cents per kilowatt-hourRead more >

LUBRICATION FUNDAMENTALS
Wet friction materials (posted on July 20, 2020)
Friction materials that operate in fluid media are called wet friction materials (WFMs). WFM is a compressible, porous and permeable material that operates in oil and transfers torque to and from metal plates that are in contact with the wet friction plates. When a wet clutch engages, kinetic energy is converted into frictional heat that must be tolerated by the WFM and absorbed primarily by the metal and oil. Read more >

SOLID LUBRICANTS
Solid lubricants for the aerospace industry 
(posted on July 20, 2020)
Spacecraft systems might be many thousands of miles from the nearest repair technician, so the mechanical parts must operate as intended for the duration of the mission. “If it doesn’t work, that’s the end of the mission, so it has to release very cleanly,” says STLE-member Dr. Jeff Lince, principal at Space Tribology Consulting in Culver City, Calif., referring to satellite release and deployment mechanisms. These mechanisms must hold their sensors, antennas and solar arrays very securely during launch and then release them smoothly and accurately when the satellite reaches orbit. Thus, the success of an entire mission can rest on a thin film of solid lubricant. Read more >

PRESIDENT'S REPORT 
Making the transition to ILSAC GF-6 (posted on July 20, 2020)

I started my formal working career at the age of 16 at a large national automotive hardware and sporting goods store, working part time while going to high school. One of my first responsibilities was maintaining and stocking the shelves in the automotive section of the store and, in particular, the old engine oil cansRead more >
