Zusammenfassung:The disclosure relates to a bell cup for a rotary atomizer for spraying coating agent (e.g. paint), with a spray-off body with a ring-shaped spray edge for spraying the coating agent, a hub part. Assembly of the bell cup on a rotatable hollow shaft of the rotary atomizer, and a fastening arrangement for form-fittingly fastening of the bell cup on the hollow shaft of the rotary atomizer. The disclosure provides that the fastening arrangement in the outer lateral surface of the hub part has a ring-shaped clamping surface that is inclined to the axis of rotation of the bell cup for the contact of a clamping element of the Rotary atomizer in order to clamp the bell cup with an axial clamping force on the hollow shaft of the rotary atomizer.
