The new electro-hydraulic solutions can revitalize hydraulics

The analyses of the new market trends show that in the next future hydraulic and electric drives will increasingly merge. The fluid power sector is changing and big manufacturers have realized it. What…

Electro-hydraulic systems, potentialities and limits

It is common opinion that the integration with electric systems will play a relevant role in the future of hydraulics. What are, however, the characteristics of electro-hydraulic systems, what the achievable advantages and…

Friction phenomena in pneumatics

In this article, we are describing the friction phenomena in pneumatic components, discussing some modelling aspects and some energy and manufacturing implications. The friction phenomenon arises also in pneumatics, which performs motions, regulations,…

Bearing materials key to increased reliability

The use of application-specific bearing steels and surface treatments permits the reliability of bearings to be increased significantly, which in turn contributes to the reduction of machinery and equipment TCO (total cost of…

Hydraulic Fluids: Risks of fire and toxicity

Oil, which can be both mineral and synthetic, is the liquid generally used for the lubrication of the parts in motion and for the energy transmission. we are analysing the aspects connected with…

Increasing the heat exchange through the deposition of nanostructured materials

Will we have more efficient and performing heat exchangers, even keeping the sizes unchanged? ISTEC (Institute of Science and Technology for Ceramics), in Faenza (Ravenna, Italy), belonging to the National Research Council, has…

The Stacked TS Bearing Assembly

Where higher speeds, higher quality and higher thrust loads are present, bearings can face this challenge offering increased features and solutions. The stacked TS bearing assembly, has been developed by Timken just for…

Direct Metal Deposition gets drive shafts up to speed on container ships

A revolution in the production of sliding bearings: it’s only necessary to apply a layer of metal a few millimeters thick using the powder nozzle to reliably, cost-effectively, and easily protect the large…

A majestic work: the navigation basin on the River Po  

To make the biggest Italian river navigable all year long; to increase its navigability by 37 km; to approach Italy to the standards of the most advanced European Countries: this is the goal…

New materials discovery would allow hypersonic travel

Researchers at The University of Manchester in collaboration with Central South University (CSU), China, have created a new kind of ceramic coating that could revolutionise hypersonic travel for air, space and defense purposes….
