Abstract
A rotary atomizer component, such as for a steering air ring or bell cup for a rotary atomizer with at least one steering air jet for delivering steering air (or controlled air) and a rotary bearing shaft where, in axial direction between the bell cup and the steering air jet, a circumferential annular gap is located. A shaft cover in form of a bushing covers the bearing shaft, when mounted, at least partially in the annular gap area between the bell cup and the steering air jet. In addition, the annular gap space between the front surface of the bearing unit and the internal surface facing it axially or any other front element of the atomizer is sealed in a radial way internally against the externally accessible area of the shaft. The sealing element provided for this purpose is located along the internal circumference of the air-steering rings or front element and able to be attached to the front surface of the bearing unit in a way that it is elastically deformable.
