FIELD: machine building.

SUBSTANCE: invention relates to production of turbines and may be used as free spherical plain bearing of turbine rotors operated at high rpm (n≥3000 rpm) and high specific load (q≥20 kgf/cm²). Proposed bearing comprises self-aligning segments each provided with axial thrust, cage with oil feed channels and radial thrusts for said segments, base, springs and locating shim.
