perspective view the surface section 3 of the roller bearing 1 is here for example a metallic sealing washer 3 on which the first electrically insulating layer 5 is deposited in at least one section as further shown in fig1 a first electrically conductive layer 7 that forms multiple conductor paths 9 with contact positions 11 for the electrical contacting of electrical components 6 a 6 b is provided over the first electrically insulating layer 5 the first electrically insulating layer 5 is preferably formed by a powder coating on the surface section 3 the first electrically conductive layer 7 is then formed by means of an electrochemical metallization on the first electrically insulating layer 5 the construction and connections of the electrical components 6 a 6 b are realized according to a method known from the prior art for mounting components on surfaces fig2 shows a schematic side view of a part of the roller bearing 1 with another embodiment of an electrical circuit 10 connected to the roller bearing 1 preferably the first electrically insulating layer 5 is structured here at a position 19 up to the surface section 3 of the roller bearing 1 at this position 19 an electrical contact element 13 is formed so that the electrically conductive layer 7 is connected in an electrically conductive way to the roller bearing 1 it is further shown here that the electrical circuit 10 has as electrical components preferably both passive electrical components 6 a and also electronic components 6 b at the contact positions 11 of the conductor paths 9 fig3 shows a perspective view of an electrical circuit 10 produced on a surface section 3 of the roller bearing 1 which has already been described with respect to fig1.
