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, 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 [...]
