A climate chamber apparatus for airtight, rotatable guiding a shaft through an opening of a climate chamber wall can include a roller bearing for receiving the shaft and a one-piece seal of an elastic material. The one-piece seal can include a roller-bearing receiving section, with which the roller bearing is connected, a wall receiving section, and a flexible connection section which gaplessly connects the roller-bearing receiving section with the wall receiving section. Further, a climate chamber with a heating chamber wall, a ventilator disposed on the wall, where the ventilator includes a motor, disposed external to the wall and which drives across a shaft, guided through the wall, a fan impeller, wherein the wall includes an opening which is sealed airtight such that the shaft is guided airtight through the wall.
An apparatus, comprising:
The apparatus 1, wherein the wall receiving section is annular.
The apparatus 3, wherein a side of the wall receiving section that faces away from the roller bearing comprises a groove for inserting the outer margin in an opening of the wall.
The apparatus 1, wherein the wall receiving section, at least in sections, tapers conically.
The apparatus 1, wherein the roller bearing is clamped with the roller-bearing receiving section.
The apparatus 1, wherein the flexible connection section, in a non-loaded state, comprises a first segment, which extends offset in an axial direction (A) relative to a second segment of the connection section, and a third segment which connects the first segment with the second segment and bridges an axial offset.
