Improvement of ball-bearing performance requires an optimization of desired properties of rubbery lip seals. Such an application necessitates specific material properties such as thermomechanical and tribological behaviours. These requirements led to investigate relationship between viscoelastic properties and tribological behaviour of filled elastomers. To achieve this objective, an analysis of two...
Acrylonitrile-butadiene rubbers (NBR) are widely used in the automotive industry, especially for lip seals of ball-bearings. Such an application requires specific materials properties either in terms of thermo-mechanical or tribological behaviours in the presence of lubricants. NBR filled with carbon black properly fulfils these conditions. Specifically, the lip seal contact area has to be large and...
