Abstract

A dampened bearing assembly comprises a roller element bearing having a raceway confining at least one roller element and a race with a bearing surface for bearing against a bearing surface of an adjacent component; and means for supplying a pressurised fluid to said bearing surface of the race for dampening transmission of impact of the roller element bearing with the adjacent component in use. The dampened bearing assembly is suitable for internal combustion engine applications such as bearings for inclusion in crankshaft assemblies.
