Abstract

A coupling () for the introduction of a bias voltage into a vacuum chamber. The coupling consists of a metallic ball bearing assembly (), a bearing sleeve or cup (), and an EMI shielding gasket () seated within the bearing sleeve or cup. The ball bearing assembly is fitted within the EMI shielding gasket, about a metallic shaft () which, in turn, is coupled to a source of the bias voltage. The bearing sleeve or cup is, in turn, coupled to a rotating component such as a platen, for receiving the bias voltage within the vacuum chamber.
