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.



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.

FEATURED ARTICLE

The future of lubricating greases in the electric vehicle era
(posted on April 22, 2019)
Electric vehicles (EVs) are no longer niche curiosities. Although projections vary greatly, EVs are rapidly gaining a mainstream market worldwide. As with any burgeoning technology, the surrounding landscape also is shifting rapidly. Lithium, the key element in EV batteries, is making a parallel transition from specialty product to mainstream chemical. But lithium also is the key component in the most popular lubricating greases. How will the grease market need to adapt to life in the shadow of EVs? Read more >

COVER STORY
Can you grease a squeaky wheel and still stop a train? (posted on April 22, 2019)
Trains traverse the land, weaving disparate communities into a single fabric (1). Ubiquitous, their presence is usually marked by their metal wheels clacking along metal tracks. On long, straight, flat rails, metal meeting metal moves the train along at a constant speed easily and safely. But come upon a curve, a hill or the end of the line and circumstances change. A curve needs slip, a hill needs traction, trains must stop. Read more >


MARKETING TRENDS
Analysis: The global polyisobutylene market (posted on April 22, 2019)
Polyisobutylene (PIB) is a liquid or semisolid vinyl polymer formed by the cationic polymerization of isobutylene, but the raw materials also can include mixtures of isobutane and isobutylene and fractions of C4 hydrocarbons along with isobutylene. The C4 hydrocarbons are derived from naphtha of a crude oil refinery and also can be a derived from plants where natural gas is used as a feedstock.  Read more >

PRESIDENT'S REPORT 
Is it globalization or being global? (posted on April 22, 2019)
The question about what we are doing globally comes up more than you know. This is not only because it is exciting to consider interactions outside of your home country but also, as many of us work for global companies, we see the opportunity to extend our value proposition (Connect, Learn, Achieve) around the world. Therefore, I want to dedicate some space to explain what we have been doing (and not doing) globally. Read more >
