Tailored bearing surfaces for optimum operating characteristics

摘要

SKF researchers have discovered that superimposing patterns on the surface of rolling bearings, in the way that tyres are patterned to improve road holding, can be beneficial in some situations, especially under poor lubrication conditions. Now the focus is on determining the best way to modify the bearing surface to further optimise performance. The researchers have developed a new methodology, which is opening up new possibilities for bearing operation and design. SKF believes that this represents a significant advance in the understanding of the role surface topography plays in bearing operation. It has considerable implications for existing finishing processes used in bearing manufacture and is supporting the evaluation of new finishing techniques. One of the immediate consequences of this development is that it can support customers with advice related to thin film lubrication conditions that are found in a wide range of applications.
