Abstract
The aim of the invention is to obtain a cost-effective solution for providing a microsystem with bearings, which have sufficiently high precision and long-term stress resistance. The invention proposes a method for manufacturing, adapting or adjusting a bearing portion in a fluidal microcomponent (M) comprising a stator () and a rotor (). Said rotor is rotatably supported on the at least one bearing portion (L,L) relative to said stator. Said rotor () is rotatably supported by a sleeve () inserted into said stator (), for forming said bearing portion, the at least one sleeve being inserted in said stator as a bearing sleeve and comprising an inner surface and an outer surface (). Before being inserted in said stator, said bearing sleeve () is a separate bearing component comprising an inner surface () as an inner bearing surface, which is mechanically micro-finished before being inserted into said stator (). The outer surface () of said bearing component () is mechanically permanently connected with said stator ().
