Alternativt kan maflflefefl 22 kompletteras med eller ersättas av en magnet i anslutning till medbringaren 1G, hår aníïfi med 23. Användandet av magneter förutsätter sålunda att ett undeltfyßkí Uflßflpåkflflalema 16-18 ej är nödvändigt. 530 2?

An axial bearing 21 determines. under the action of the aforementioned counterforce, skewer 1 retracted rage in the housing 1 during engagement with the exer s vie merruririø fl fe fl 10- Delta axial bearings 21 are fed with the same bearing fl uid as the radial bearings. Figure 2 indicates, one that exierrr stood for the rail 7 seems a carrier. for example in the form of a jaw coupling 10, in which case the axial bearing 20 is the effective position for working with negative pressure in the bearing surface, so that with a force retaining the shaft 7 with its tool 8 in the housing 1, this lcrafl, as shown in Fig. 2. in particular fl i is provided by a magnet 22 providing this force, which magnet 22 in the case shown is applied in connection with the pivot mass 13. Alternatively, m aníï fi with 23. The use of magnets thus presupposes that an undeltfyßkí U fl ß fl påk flfl alema 16-18 is not necessary.
