A compressor shaft rotates on
- sintered bearings
- ball and roller bearings
- plain bearings
Explanation from PART66Online
Gas-turbine compressor and turbine shafts run at very high speed and carry both radial and axial (thrust) loads, so they are supported on anti-friction ball and roller bearings. Ball bearings take the axial thrust loads while roller bearings carry the radial loads and allow for thermal growth of the shaft; plain or sintered bearings could not survive these speeds and loads.

What about Needle Roller bearings, those are not balls?
