1. A compressor device with a housing and provided with at least one compressor element and a drive for the compressor element, wherein all bearings of at least one shaft in the compressor device configured to carry static axial load, are provided with a bearing damper which comprises a coupling element and at least one damping element made of a damping elastomer material,
wherein the bearing damper is installed with the aid of the coupling element between a bearing of the compressor device and the housing of the compressor device,
wherein the coupling element allows little or no movement of the bearing relative to the housing in the radial direction compared to the axial direction,
wherein the at least one damping element is configured to dampen the axial movement of the bearing relative to the housing, and
wherein the coupling element is a ring-shaped element which includes at least two rings, and the at least two rings are held together along their inner edges and/or outer edges by an inner clamping strip and/or an outer clamping strip respectively.
