New bearings for high-speed applications

20.04.2018 tribonet 1,001 Views

A clear trend in compressor and pump applications is to raise the power density by increasing the rotational speed. To fulfil this requirement, SKF has developed a new range of single-row angular contact ball bearings. […]

Superlubricity by means of repulsive van der Waals forces

06.04.2016 808 Views

Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may [...]

The internet is full of videos of people having fun running over white slime. It almost looks as if they were walking on water. But when they stand still, they slowly begin to sink. The [...]
Adhesive Wear Particles Generation: by Fracture or Atom-by-Atom?

The most famous equation to predict wear known probably to everyone working in the field of tribology is Archard’s model (1953). The model assumes that wear occurs through the fracture of plastically deformed material and [...]
