A control cam (6) radially guides the rod (3).

Each radial guide (1) is formed by guide blocks (11) arranged between two rams (2) and rigidly connected to support rings (12) arranged on the front face.

The shank (5) of the utensil is provided with a bearing unit (50) therefor, comprising a corresponding truncated cone-shaped recess (51).

Said slits extend in the longitudinal direction of said rotor.

Said brake pad comprises guiding surfaces (11, 12) which are arranged on the lining shaft (10) and which guide the brake pad in a radial and tangential manner.

Both parts are then connected to each other in a positive and/or non-positive way.

A side channel pump (1) has guides (17), for the radial and/or axial guidance of the turbine (4), arranged in the radially external region thereof.

A radial guide element (10) is fastened or can be fastened to the bearing pin (7) and/or the worm gear (6) in order to absorb radial forces.

The invention relates to a mounting for a turbo-machine rotor (16).

Said mounting is characterized in that radial support of the rotor is assured by one or more permanent magnet bearings (20, 22).
