CFD simulation of lubricant flow in bearings
Computational Fluid Dynamics (CFD) is a science that studies various fluid flows and flow related behaviours with the aid of computers. CFD is increasingly used to produce quantitative predictions of flow behaviours and get more insight into the flow behaviours...
New bearings for high-speed applications
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. The goals have been threefold:...
White etching cracks
Today, bearing failure due to rolling contact fatigue is generally a rare occurrence, and the final achieved service life of rolling bearings is usually well in excess of the calculated rating life. There are instances, however, where in specific applications...
World’s most powerful large-size bearing test centre in operation
SKF has a broad portfolio of extremely powerful software for the calculation and simulation of all types of rolling bearings. Among these are highly complex systems, which can investigate bearing behaviour in a virtual environment: With the tool SimPro Expert,...
Benefits of Hybrid Bearings in Severe Conditions
Hybrid bearings, i.e., bearings with steel rings and bearing grade silicon nitride (Si3N4) rolling elements, have been increasingly used in applications operating in challenging environments [1-4] such as high-speed, oil-free air conditioning and refrigeration compressors, general fluid machinery, electrical machinery...
