Tribology is the science dealing with interactive surfaces in relative motion and includes the study of friction, wear, and lubrication and how these properties affect design. The term tribology was coined in 1966 by Peter Jost, the man considered the founder of tribology. Leonardo da Vinci...Read More »

What time does it take before the minute parts of microscopic equipment become unusable as a result of deterioration? What warning signals do you need to watch out for that will show that the components will soon fail to function as required? In a bid to provide swift...Read More »
Since the 1800s, railway organizations have been struggling with low adhesion on the rail, especially during the Autumn season also known as the “slippery track season”. In Autumn, leaves fall on the rails and when train wheels crush the leaves, they become a layer of oil...Read More »
Tribology is the science of interacting surfaces in relative motion. Basically, it studies friction, wear and lubrication – three phenomena linked to surface degradation and, thus, to machine reliability and performance. When machines wear out, they perform worse, are less productive and, finally, begin...Read More »
In dry sliding between a given pair of materials under steady conditions, the coefficient of friction may be almost constant. This is the basis for two EMPIRICAL Laws of Sliding Friction, which are often known as Amontons’ Laws and date from 1699. They are in fact not...Read More »

Here we present an abstract to a paper devoted to the history of eastohydrodynamic theory and his founder – Alexander Mohrenstein-Ertel. This paper discusses in detailes the peculiar biography of the scientist and the early years of the theory development.
No future without history! A great article on the history of great discoveries in the field of contact mechanics and friction was recently published by Elena Popova and Valentin L. Popov. Here we present the abstract of the article.
‘The correct lubricant’ covers basic practical information about lubricants in automotive and industrial areas. It is written for users of lubricants, giving only what is essential to know and useful for them. It could also be used by professionals in the field who must explain various aspects of...Read More »
In a rolling bearing, the load transmission is often accompanied by high contact stresses which may eventually lead to wear and/or fatigue. In order to ensure separation of moving parts leading to a long life, bearings are usually grease or oil lubricated. The separation of the moving parts in a...Read More »
Lip seals compete with mechanical face seals in sealing oil or grease in rotary shaft applications. Under certain running conditions both kinds of seals can be used however, the latter ones are generally used for applications where a significant pressure difference needs to be preserved. Rotary lip seals are preferred...Read More »
September 1 of 2016 at Cape Canaveral SpaceX lost is Falcon 9 rocket on a launch pad due to dramatic explosion. During a routine preflight fueling test, the rocket and the $200 million Israeli Earth communication satellite Amos-6 were lost. No one was injured.
A rolling bearing preferably runs under EHL conditions. The film thickness between the rolling elements and the rings is...Read More »
