ABSTRACT:
The pointer shaft 1 of a rotary-magnet ratio meter is mounted by means of radial bearings (15 and 20 respectively) one near its pointer 2 and one at the end facing its rotary magnet 4. The lower radial bearing 20 arranged near the rotary magnet 4 is formed by a blind hole 16 into which the pointer shaft 1 engages and in which it rests on a metal ball 19. This metal ball 19 therefore forms a thrust bearing 20.
