1. A bearing assembly for a turbo-engine, comprising:
a bearing and parts of a bearing temperature detecting device,
wherein the bearing comprises:
a main body having a first surface, onto which a thermoplastic bearing layer is adhered, and a second surface which is opposite to the first surface, the thermoplastic bearing layer forms a bearing surface,
a space is defined in the interior of the main body and the thermoplastic bearing layer at least for accommodating the parts of the bearing temperature detecting device,
wherein the space comprises a first hole, wherein the first hole is a through hole having a first opening located in the bearing surface of the thermoplastic bearing layer, and a second opening located in the second surface of the main body,
wherein the parts of the bearing temperature detecting device comprise:
a temperature conducting element having a peripheral surface and a first end with a first end surface,
a temperature sensor in contact with the temperature conducting element and
a securing fixture that attaches the temperature conducting element resiliently to the main body,
wherein the temperature conducting element is assembled into the through hole such that its first end surface is either flush with the bearing surface of the thermoplastic bearing layer or is located below said bearing surface, and
wherein the first opening of the through hole comprises convergent cross sections as seen from outside to inside the first opening and the first end of the temperature conducting element comprises a head which is correspondingly shaped to the convergent cross sections of the through hole in a form fitting manner with the convergent cross sections of the through hole.
