The friction between the nylon body 9 and the casual is straight sufficiently large to prevent undesired rotations of this bearing, aThe aie is not yet large enough to allow self-centering reward.

Jis gives another advantage of the room 12. Sintered i-metal bearings are mostly used as self-lubricating bearings, which due to their porosity hold the lubricant e.g. oil. During the development of the heat however, some of this oil is sometimes expelled and lost goes. With the described design, however, the OeI collects in room 12 and when it cools down, the oil moves back into the store, so that no Lubricant is lost while the heat is dissipated well.

The described design, which in practice is very good, result results, is particularly suitable for use with relatively thin Axes * e.g. with a maximum diameter of 6 mm, for which they also
