Abstract
A cassette seal is configured to seal a shaft within a housing. A shaft casing is annularly-shaped about a longitudinal axis and is configured to fixedly attach to the shaft, where the shaft casing is electrically conductive and configured to be in electrical conductivity with the shaft when attached to the shaft. A housing casing is annularly-shaped about the longitudinal axis and is configured to fixedly attach to the housing, where the housing casing is electrically conductive and configured to be in electrical conductivity with the housing when attached to the housing. A seal is disposed between the shaft and housing casing. At least one cantilevered flexural finger is attached fixedly attached to either the shaft casing or the housing casing and then in rotating abutment with the other. The at least one cantilevered flexural finger is electrically conductive and electrically connects the shaft casing to the housing casing.
