Rotary atomizer component

A rotary atomizer component for a rotary atomizer the rotary atomizer having an atomizer casing,

• the rotary atomizer having a bell cup mounted on a rotary bearing shaft, the rotary bearing shaft having a bearing unit,
• the rotary bearing shaft having an annular gap between a front surface opposite the bell cup of the bearing unit and an internal surface opposite in axial direction of a front element,
• the rotary bearing shaft penetrating the annular gap, and
• an area between bearing unit and the bell cup of shaft is accessible for media from the surroundings of the atomizer,
• the rotary atomizer component comprising a sealing element surrounding the shaft in a form of a ring that seals at least part of the annular gap located between the front surface of the bearing unit and the internal surface opposing it against the externally accessible area of the shaft.
