The invention relates to his protection device for bolt holes. Against rapid wear of surfaces on bolts, iushateilohan, holes or bores or the like are known differently. 31 © are, however, both in the »production as well as due to the 4 property © ® the usual starting material is cumbersome and expensive; is used as the starting material E.g. if a pipe is chosen, the exact adherence to the required pairing is sohwisrlg. Such protective devices are therefore until now only been carried out for certain aeha or bolt constructions.

It is essential that the protective device is fitted to wear and tear on the outer surface that comes into contact with one another to increase if possible. The protective overlay should therefore be extremely strong, frotzdsm will appear after a certain tent Stress and replacement may be necessary, and in this regard, the known processes are very cumbersome Trouble.

With long axes, the heat treatment results in the risk of a mistake, which requires subsequent, cumbersome alignment. For such an axis, a correspondingly larger diameter must also be made before the hardening, because after the alignment the hardness delay is the dimensional accuracy must be sought by grinding over the entire length. Are certain places useful? Axes are declined, for example by swelling
