An x-ray device is presented. The x-ray device includes a cathode configured to emit an electron beam. Further, the x-ray device includes an anode having an anode surface configured to generate x-rays in response to the emitted electron beam impinging on a focal spot on the anode surface. Also, the x-ray device includes a reciprocating assembly including a drive shaft operatively coupled to the anode and a first bearing unit operatively coupled to the drive shaft, where the first bearing unit is configured to translate the anode via the drive shaft to distribute heat generated in the anode. Moreover, the x-ray device includes a first diaphragm disposed between the anode and the first bearing unit and configured to cease a flow of one or more first lubricants from the first bearing unit towards the anode.
