“…Finally, recently GrMaTS has focused on studying greases used in the wheel/rail pair [313,362] and labyrinth seals [314,315]. Besides, methodologies have been developed to investigate tribocorrosion of duplex stainless steels [316], to determine the kinetic friction in journal bearings [317], to assess particle abrasivity [318], and to identify the maximum resolution when measuring wear by optical interferometry [319]. In addition, this group contributed to this special issue by determining the tribological behaviour of nitrided and heat-treated ferritic stainless steel under diverse conditions [17].…”

This first regional issue published in STMP highlights the potential and importance of the research carried out in Latin America regarding surface engineering and tribology. In order to celebrate this important initiative, a complete historical account of Brazilian tribology is presented for the first time. It initiates with the first steps of Brazilian tribology in the 1980s, followed by the evolution and expansion of tribology research both in academic centres and industry. Focus is given to two outstanding achievements of Brazilian tribology: the fully flexible engines that run at any proportion of ethanol and gasoline and a fully innovative, completely oil-less family of hermetic compressors. The status-quo of the current research groups on tribology is described. Finally, the future trends envisaged by the Brazilian tribology community are presented.

“…The friction torque, together with vibrations and durability, is one of the most important parameters determining the quality of bearings and their suitability for the intended applications. The friction torque contains a great deal of information about the bearing, whether in terms of its design, the quality of its mating parts, its cleanliness or certain lubricant properties [9] and [10]. Given the widespread use of bearings in the automotive, machinery or household appliance industries, a need is being generated to reduce friction in rolling bearings, which is a key measure in the quest to improve efficiency, reduce energy consumption, and protect the environment.…”

The frictional moment, together with vibrations and durability, is one of the most important parameters determining the quality of bearings and their suitability for the intended applications. The frictional moment value allows for obtaining essential information about the bearing, both in terms of its structure, the quality of mating elements, cleanliness and the specific qualities of the lubricant used. Since bearings are commonly used in the automotive industry, machine industry and household appliances, the need to reduce friction in rolling bearings is critical to increase the bearing efficiency, reduce energy consumption and protect the environment. The article presents a new industrial device for testing the bearing frictional moment of rolling bearings at the stage of their production. The device is characterized by an innovative design that allows for testing a wide range of bearing dimensions, applying significant axial loads, additional measurement of the mounting width of the bearings, and most importantly, testing the cone bearings. This article presents the general assumptions and the mechanical design of the new device for measuring the frictional moment of rolling bearings, as well as the verification of the device indications based on a measurement procedure performed in industrial conditions.
