In screw compressors for extremely high discharge pressures, the geometrical centers of all coaxial holes or housing bores are all located in one single housing section on the male rotor side at a certain first straight line and the geometrical centers of all coaxial holes or housing bores are all located in one single housing section on the female rotor side at a certain second straight line. The diameter of all coaxial holes in the housing on the male rotor side, and the diameters of all coaxial holes in the housing on the female rotor side, decrease from the open to the closed end of the housing section. Based on this construction, the bearings and the components adjacent to the bearings are guided at their periphery in one single housing section so that there will be no coaxial deviations caused by assembly and no coaxial deviations in long term operation.
