The invention relates to a method for producing, adapting and/or adjusting at least one bearing in a fluid mini- to micro-component (M) comprising a stator (30) and at least one rotor (40, 2). Said rotor is rotatably positioned on the at least one bearing (L10, L11) in relation to the stator. The inventive method is characterised in that (a) the rotor (40, 2) is rotatably positioned by means of a bushing (10, 11) which is inserted into the stator (30) in order to form the bearing, the at least one bushing being inserted in the stator in the form of a bearing bushing and comprising an inner and an outer surface (10i, 10a; 11i, 11a); (b) before being positioned in the stator, said bearing bushing (10, 11) is a particular bearing component comprising an inner surface (10i, 11i) as an inner bearing surface which is mechanically finish-machined before being positioned in the stator, and; (c) the outer surface (10a, 11a) of the bearing component (10, 11) is connected to the stator (30) in a mechanically fixed manner.
