Abstract

An antifriction bearing provided with sensors for recording physical quantities that act upon the hearing and with strip conductors and electronic components for evaluating and/or transmitting sensor output signals or characteristic values derived therefrom to electrical or electronic devices located outside of the bearing. To this end, the sensors, strip conductors and electronic components are placed on at least one bearing part while forming a measurement data recording and/or measurement data processing system. The sensors, strip conductors and/or electronic components are made from at least one electrically conductive or semiconducting organic material.
